Good question - I get this from time to time. The $ symbol is hexadecimal programming language. Skip to 2:18 and you'll notice that the scanner shows this too. Just ignore it. The more advanced bi-directional OBD scanners break it down while others do not break it down. I include it anyways so the user can follow the guide with clear instructions.
Thank you! Purchased the CP9680 and was finally able to find the misfire - it was a bad coil on my first cylinder. The tool itself cost the same as a diagnosis at the dealer, but now I can chase down any misfires in the future!
Your awesome for the tip. No check engine light and she’s misfiring. Instead of running it with a miss like that, checked test $53 and boom! Misfire on #6. All others good. You are the man!
Man I really have to thank you for this video. I ordered a cheap reader that claimed it had mode 6 which it didn’t. Ended up returning and going to oreileys to use the one they had in house. Took me a second to find but it found that cylinder #7 was the one misfiring. Fixed my problem and saved me about $800 bucks in changing all of them. You are the man!
Thanks for the info . I have the Actron CP9690 tool . I have a friend's 2000 Honda Accord , 2.3L . The CAT is restricted . The O 2's are showing rich . I need to find where the issue is so a new CAT is not ruined . Misfires are a good starting point .
Bill Smith Check plugs, plug wires, injectors, fuel mixtures, clogged air filter, leaky valves, stopped up muffler, and faulty emission control parts. Check the codes and fuel trims and other readings. A bad coolent temperature sensor can cause a rich mixture. Look on live test with the key-on engine off with the engine cold. See if the coolant temperature reading is about the same as outdoor temperature. If it says 33° and it's 88°, the coolant sensor is bad. That can cause a rich mixture. Read on UA-cam how to detect a bad cat. converter. Check record and then graphing on O2 sensors to compare readings.

Thanks, couldn’t figure out which test was my individual cylinders. My 2003 Mazda B2300 I4 is showing 4085 events with a maximum of 14080 for a fail on cylinder 1, while the others are zero events. I just changed my plugs and wires (it needed them) so I’m gonna keep an eye on this number to see if it goes up. One thing that has been really confusing is the event count on test ID $56, it just keeps counting up and up with big numbers for a Fail state because it wants a maximum of 2000. I’m not really sure what to make of that one…
And now I know what to look for using your information. Thank you so much for sharing your knowledge and expertise. You have saved me a lot of money Sir. God bless you... Take care, and stay safe.
Great explanation of misfires. I recently bought a used 2002 f150 with 4.6l engine. Has hesitation issues at 40 miles an hour. I had already checked the OBDII for codes (none). after watching your video I went back into my inexpensive reader found Mode 6. Turns out I have many misfires in cyclinder #6. Thanks for the help. :)
I replaced all the coils and spark plugs. I installed Ford Motorcraft coils 3W7Z-12029-AA and NGK Iridium spark plugs. Now the transmission shift perfectly and the engine runs better.
Thank you for video post. I have read code device to hook up 2011 ranger 2.3L. To find misfire. I see number but did not light on yet. Pull out number 2 wire spark and it wet. I put dry it out. It run much better. I’m happy but I has to deal “wet” into wire spark plugs. I will buy spray for water proof.
Hi!!! I just ran mode 6 in my 2001 expedition. I have: $2A $00 FAILURE $2B $00 FAILURE $26 $00 FAILURE $56 $00 FAILURE Can't find definitions on those codes, or what they are related to. Can you help me?
To my knowledge modern GM vehicles break down the hexadecimal language to layman's terms. It should just show the actual cylinder number in English instead of hexadecimal language.
I'm not sure if it's a misfire or the torque converter but its been "Shuddering/Vibrating" between 30-45mph since about 2016. Also does it uphill sometimes. No scantools were showing anything wrong and I dont wanna just throw parts at it.
Yeah, don't throw parts at it. If you don't see any misfires in mode 6, you would need a more advanced scanner to perform a "power balance test". It's the graph line test that allows you to actually see the misfire and in which cylinder it occurs. This would further help you see what's going on with your motor. This would be a much more in depth test than the mode 6 and help you to pinpoint your issue down to an electrical or mechanical issue.
Hi I don’t know if you still have the problem or even the truck but I’ll put it here so people know what’s wrong it’s a misfire I had the same thing on my truck and replaced the spark plugs and it was good as new so id try replacing them first as they are the cheapest and if it’s still there try the coil packs you can do all this in a day unless you have the 5.4
hello, nice video. i just got my maozua z100 obd ll can scan tool with mode 6. but do not no how to use it to get to the spot to check for misfires, like yours. you seem to no a lot about how to use them. no videos on you tube about the maozua z100. i have a 07 f150 with a 5.4 you sed in your video tools needed, obd ll can scan tool with mode 6. pleas help if you can, thanks Bob
I've been looking around for a while to see if I can find the menu info from the Maozua Z100, but can't find anything. If I'm able to find anything I will share it here, or even make a full how-to video with that scanner.
I just bought actron cp8680 to check my 2004 ford expedition for the same problem that you are talking about but the menu on the screen is different and does not show me the functions that you used.
I looked up Actron cp8680 and I didn't see a model that existed. Did you mean Actron cp9680? What does your screen show? Does it have the "Special Tests" section?
Update, the Actron code reader did find cylinder #5 was miss firing. HOWEVER, my reader PC9680 gave me the misfire info in Hexadecimal which at that tinme I didn't recognize. after scouring the internet, i found a page where the author described the Hexadecimal codes and told how to go to my PC calculator and set it for scientific mode. I was then able to decode my results. Just remembered I already did an update to this post. Oh well go below and read it in more detail.
Thanks for this video. I bought this exact scanner for my 97 5.0 to detect a misfire and under $51 it shows cyl 3 STS as "HI" where the other cylinders show "OK". Do you know what "STS" stands for?
STS is just a representation for the check engine light. I believe it stands for "self test status", but not 100% sure. HI most likely means that it records misfires, but not enough to not set the check engine light on. How many misfires does Cyl 3 show?
Very interesting, I knew my car was misfiring. On my Acura I had a misfire so bad it was clearly only running on 5cyl, no engine light. So I had to go old school and just unplug coils until I found the right one. But my Ford it's just a slight miss.

For all of the scanners I've used, it only needs to be in the "run" position...Aka lights on the dashboard on, engine off. Some scanners will tell you to start the engine.
A word of caution... 96 was a transition year so you might have a 96 Ford that actually has a 95 EEC-IV ignition system which means a scanner with a Mode 6 is not going to be of any use to you.☹
I bought a scanner that uses mode 6....I ran it and I found 5 misfires on cylinder 2 out of I forgot how many max value....then I got 10 misfires out of 934 max on $54 test....my question is I can't get this to change? I want to test again specially at low idle speed because that's when I feel I have the most misfires....is there any way you know how to do this?
@@araparts is there a scanner I can buy that will give me access to live misfire data? I really need to view what is happening at idle and specifically right when I start up the car as that's when I feel it shaking....with mode 6 on my cheap scanner I do get misfires but I have absolutley no clue when these misfires were recorded....they could be on the highway at 70 mph 2000rpms or they could have been in park idle....I need to view these misfires live
Followed yours and fixed misfire in 91 Expedition. Great video/explanation. How did you know what test 53 was going to show/references for other test numbers?
I'm getting a measurment reading that says "17ca" on my cylinder number 5 on my 03 expedition. Any ideas what that meens? I'm experiencing a bad misfire with mo check engine light
Depends on the scanner and what format it uses. It might simply mean a misfire. I would try swapping the coil from cylinder #5 to a different cylinder to see if that number follows the coil.
Doesn’t explain why this is happening or what to do about it. So why buy a scanner? My truck is an 01 with the 5.4 2v. It has been running exceptionally for 154k miles and I keep it serviced. Occasionally it develops a misfire at idle up to about 1,500 rpms. Sometimes it does it for a few minutes and stops. Sometimes it lasts for weeks. But mysteriously it eventually stops. But now I’m going on two weeks and it’s annoying. No check engine light either. I’ve been told it has something to do with the PCU. And there’s a way using a scanner to go into the PCU and correct a code?
This won’t solve the problem, but it will help you quickly isolate it. You also can’t correct codes. You can only delete them. There are multiple things that can cause a misfire. PCU - that would be the main computer. It is commonly referred to as “PCM, ECM, or ECU”. It stands for “power train control module”. Mode 6 is one way to access any misfire data that is being stored in the PCM. Ignition coils are by far the most common (which was the case with the one in the video) but there are many other things that can cause a misfire (fuel injectors, cam/crank sensors, timing chain, cam phasers, corroded wiring, rodent damage, bad PCM drivers (more common on the Escapes) and the list goes on. If you don’t want to buy a scanner, you can see if the local auto part stores are willing to view mode 6 data (their scan tools are usually capable) or you can wait for the service engine light to turn on and you can pull the codes with any $5 scanner. Service engine light will turn on once the misfire gets worse.
Mine missed right before the spark plug blew I just got it out the shop like a week now and it’s missing again and I’m worried I’m about to blow another plug
A little off topic but if I have a check engine light on but when I plug in my obd scanner.. I get no codes.. Does anyone know why this happens? I had a p0420 before.. Changed the 02 sensors.. And cleared the code.. Then a few days later and over 100 miles driven.. The check engine light is back.. But no codes whatsoever..
P0420 is typically a bad catalytic convertor(s). I've seen O2 sensors cause that code, but more often than not that's a bad cat. Especially if you clear the codes, change the O2 sensors, and P0420 keeps coming back. You can have a smog shop diagnose it further before spending the money on anew one (s).
It doesn't actually say "Mode 6" on a lot of scanners, but it will actually say Mode 6 when purchasing a scanner because that is the name of that particular function. You'll have to pay attention to that detail. It is called "diagnostic monitor tests" for my particular Actron scanner.
Yes, other manufacturers for newer vehicles usually display the data in layman's terms rather than hexadecimal language. I know GM trucks will literally show "misfire count cylinder 1, 2, 3, etc". Not all vehicles support this feature however.
It will. For Toyota vehicles of this age, the computer actually decodes the hexadecimal language to layman's terms. It will simply tell you which cylinder number, etc.

😂 these Fords do have their issues, but most modern cars these days aren't free of problems and recalls. We've seen a pretty level playing field across the board (aside from luxury cars - as usual).
If Mode 6 isn't giving you data you need, I'd recommend looking up the term "cylinder power balance test". Unfortunately, this test will require a much more advanced and expensive scanner. As an avid DIYer, I'd always say the more tools the merrier. It really depends on your DIY dedication whether or not you would buy a scanner with this type of capabilities, or just take it to a shop who can perform this type of test.
@@araparts I read that BB5 is actually a Hexadecimal value. www.totalcardiagnostics.com/support/Knowledgebase/Article/View/48/6/mode-06-diagnostics (MODE 06 HEX CODES) When I converted it on the windows calculator it came up to 2997 in decimal. I replaced number 5 coil pack a few days ago. No problem now. I ended up getting my Actron cp9680 on sale for $145. Pertronox aftermarket coil pack $30. All in all $175 fix. A heck of a lot cheaper than the mechanic shop. Thanks again.
I have 2012 e350 ford Can this tool find inactive codes My van few times has flashing mill light after stops does not shows codes Where can buy this scanner?
Yes, is the engine is misfiring, you can use mode 6 to identify those misfires with this scanner. This scanner is the Actron CP9680 and can be found on many websites like Amazon, JBtools, ebay, etc. Other scanners will do this too, but just make sure it has "mode 6" functionality.

Ben Smith I’m wondering the same thing. Actron advertises the 9670 as “mode 6 in layman’s terms” so I’m assuming it will do mode 6
What was the fix on this truck? Spark plug? Coil? Or ?
It was just one coil.
Araparts how did you know which coil it was?
Nedrea Spivey Watch the video and the explanation of the Mode 6 test data.
A little off topic but if I have a check engine light on but when I plug in my obd scanner.. I get no codes.. Does anyone know why this happens?
I had a p0420 before.. Changed the 02 sensors.. And cleared the code.. Then a few days later and over 100 miles driven.. The check engine light is back.. But no codes whatsoever..
P0420 is typically a bad catalytic convertor(s). I've seen O2 sensors cause that code, but more often than not that's a bad cat. Especially if you clear the codes, change the O2 sensors, and P0420 keeps coming back. You can have a smog shop diagnose it further before spending the money on anew one (s).
I couldn't see nothing on your screen which you showed as code 6 and what's it for
It doesn't actually say "Mode 6" on a lot of scanners, but it will actually say Mode 6 when purchasing a scanner because that is the name of that particular function. You'll have to pay attention to that detail. It is called "diagnostic monitor tests" for my particular Actron scanner.
will this also apply aside from ford? if so, which brands?and thanks for this info.
Yes, other manufacturers for newer vehicles usually display the data in layman's terms rather than hexadecimal language. I know GM trucks will literally show "misfire count cylinder 1, 2, 3, etc". Not all vehicles support this feature however.
noel colendrino Check on Google for a Actron CP9680 about the cars it covers.
will this work on a 2007 camry?
It will. For Toyota vehicles of this age, the computer actually decodes the hexadecimal language to layman's terms. It will simply tell you which cylinder number, etc.
2000 ford ranger? 3.0 any help please
Tiffany Gould The Actron CP9680 will work on your car. EBAY has it. It checks live, record, graphing, transmission tests, ABS, SRS, oil light reset, and MORE! Get 4 aaa batteries for under the rear cover. Get a USB cable to update it. Get a wall charger cable for a Tom Tom One GPS to review test results in your home. Get a Tom Tom One GPS cigarette lighter cable for in-car test results review. Get a cigarette lighter extension cable for extended use. Hook it up to the test connector. Turn the ignition on. Read codes. It shows the definition. Check code-connect to diagnose codes. Start the engine to check operating conditions. It comes in a black pouch. EBAY has them. This saves money from having to take it to a mechanic.
What scanner are u using?
Not the "man" but looks like a 9680
This scanner is the Actron CP9680.
Thx guys!!!
Only works on Ford or any car ?
Many cars use Mode 6. The newer the vehicle, the more likely you can pull this data.
What model actron is this?
This scanner is the Actron CP9680.
have you tried it on a mustang?
Alexander It'll work on a Ford Mustang. It's a Actron CP9680. EBAY has it.
You mean the "check engine" can ever go off on a Ford?
😂 these Fords do have their issues, but most modern cars these days aren't free of problems and recalls. We've seen a pretty level playing field across the board (aside from luxury cars - as usual).
Tcmtech Usually Ford's have bad MAF sensors.
Hey there, does your actron sometimes show hex format for misfires like letters and numbers (ie. 7f) instead of just a regular number?
I haven't noticed that with this scanner to be honest.
Didn’t help me. Mode 6 isn’t showing a specific cylinder, just a general misfire on test 56.
If Mode 6 isn't giving you data you need, I'd recommend looking up the term "cylinder power balance test". Unfortunately, this test will require a much more advanced and expensive scanner. As an avid DIYer, I'd always say the more tools the merrier. It really depends on your DIY dedication whether or not you would buy a scanner with this type of capabilities, or just take it to a shop who can perform this type of test.
My Cylinder 5 "MEAS" =BB5 what the heck does that mean? No numerical value just BB5?
Using Actron cp9680
Not sure what that means. If you have a misfire, I would swap #5 to a different cylinder, clear codes (if any) and re-test.
@@araparts I read that BB5 is actually a Hexadecimal value.

(MODE 06 HEX CODES)
When I converted it on the windows calculator it came up to 2997 in decimal. I replaced number 5 coil pack a few days ago. No problem now. I ended up getting my Actron cp9680 on sale for $145.
Pertronox aftermarket coil pack $30.
All in all $175 fix. A heck of a lot cheaper than the mechanic shop.
Thanks again.
I have 2012 e350 ford
Can this tool find inactive codes
My van few times has flashing mill light after stops does not shows codes
Where can buy this scanner?
Yes, is the engine is misfiring, you can use mode 6 to identify those misfires with this scanner. This scanner is the Actron CP9680 and can be found on many websites like Amazon, JBtools, ebay, etc. Other scanners will do this too, but just make sure it has "mode 6" functionality.
I just put in a engine in my 04 Ford expedition and the engine light started blinking 3 time and it would shut off and back on 3 time.. before I put the engine in it was sitting for 7 months would bad gas be a problem
Crystal Smith Run it so the computer can build codes. It might give a code P1000, meaning the car sat or the battery was dead. Charge the battery and retest. EBAY has this tester.
My v10 has a slight mis at 1400-1600 rpm. Why would it not misfire all the time but only in that small rpm range? Thank you
The load at different RPM ranges is not the same. It's quite common to see misfire at higher load and low rpm.
darkjedi351 Get the Actron CP9680 and test the codes. EBAY has it. Get 4 aaa batteries for under the rear cover. Get a Tom Tom One GPS wall charger cord for in-home review of results. Get a Tom Tom One cigarette lighter cable to review results in the car. Get a cigarette lighter extension cable for extended use.
Not the "man" but looks like a 9680
śrick śrick The CP9680 and CP9690 tester are the same. The CP9680 is for OBDII only. The CP9690 has cables for OBDI Ford, G.M., Chrysler, and 2 Toyota. Also, OBDII. Get a USB cable to update it. Get a charger cable for a Tom Tom One GPS to check readings in your house. EBAY has it.
Didn’t help God bless.
Omg this guy loves to talk about crap has nothing to do with problem, cut the yack get to the point
