Toyota Dealer Misdiagnosed this Transmission
Вставка
- Опубліковано 8 вер 2024
- This 2004 Toyota Camry had a supposedly bad transmission. The dealership "diagnosed it" and sold the previous owner a new car instead of a transmission job.
The symptoms were no reverse, no first gear, slipping and struggling when going forward, the ABS and brake lights were on and the speedometer was stuck at 20km/h.
After diagnosing the speed sensors, transmission solenoids, fluid and fuses, it came down to disconnecting the ABS module to rule it out of the equation, and the transmission worked fine! The ABS module was sourced easily from a junkyard and is just 4 bolts and one connector to change. That's all it took to save this Camry from getting scrapped!
Hopefully this helps someone out there who has a similar issue.
Just imagine that the customer preferred to fix the transmission, and after all the money and work the car was still doing the same.
I know the feeling. Had an abs module failure on my golf. Mechanics misdiagnosed it as well. Thanks for the heads up.
What were the symptoms?
@@speedkar1005 The speed sensors were not reading, causing the brakes to be applied during normal driving and the traction light to activate and stay on. I thought they were suspension bushes which I duly changed. I then replaced the speed sensors after the mechanic advised after scanning the obd, it gave the same fault. Then I replaced a sensor on the brake vacuum/reservoir still no luck. After watching a few UA-cam videos I realised it's a faulty module throwing sensor faults. I wasted about NZD800 on unnecessary parts I think. Forget labour. A new module is unavailable so I got a used one. It was a good learning curve as I have not driven a car with faulty ABS before.
Great Fix! A little work and alot of knowledge scored you a great car!
Thanks. It took me 2 days to figure it out but I eventually tracked it down!
Good catch! Dealers are sloppy and it’s potluck whether you get a good tech or a bad tech. It’s a shame since they have the factory scantool and could have seen the data to diagnose the issue within minutes.
We’ve seen this a few times on Camrys and Siennas in this generation at our trans shop. The ABS module generates an aggregated primary vehicle speed signal from the wheel speed sensors which then goes to the instrument cluster and then out to the powertrain control module. This signal is used by the pcm for shift scheduling (when to shift). When the ABS module does not generate a VSS or a bogus signal (in this case), the pcm will not shift the transmission in the correct gear causing transmission symptoms. Reverse was inhibited as it saw a vehicle speed signal indicating movement.
The tell tale for most of this is no comms to the ABS module. The last sienna would not communicate but had good power and grounds and comm lines. It was just dead. It had no vss signal output and would not upshift.
When I was living in the states, I had a Kia Spectra 5 I purchased new 15 years ago. I had an incident in where the front bumper was damaged and needed replacement (within 4 months of buying). Since it was so new, I took it to a dealer body shop to replace the bumper (I figured that they could source OEM parts better to retain original value, and the insurance payment wouldn't differ on my end), within a day the sales team from the dealer tried to call me to buy a completely new Spectra 5 to replace the car that just needed a bumper replacement.
Moral of the story: dealers just want to profiteer and they try and sell brand new cars, even getting people underwater on a loan for a brand new purchase from less than a year ago, when basic repairs do the job. We live in an unjust economy, and its worthwhile for people to be vigilant rather than shell out cash needlessly. I had to basically haggle with a car sales guy that I needed a bumper replacement, not a car replacement. It was absurd, and I'll never forget that call! But then again, this is the economy we live in, and everyone seems to support it. Capitalism at its finest. You have to be buyer beware, many dealers kind of deal in fraud!
Maybe you could make a video on how to check solenoids and those transmission speed sensors if you have the time.
Part of me wanted to make a video of my diagnosis process but I really wanted to narrow the issue down first
the one dislike on this video is the tech from Toyota who still thinks this car needs a transmission ;)
Great fast paced descriptions of the jobs.
Nein nonsense.
Dealer has all the kit but this guy has the brains!
I’m coming from your “diy immobilizer hacking” video with a question.
I have a unique situation. I have two Toyota 4runners a 1999 and a 2000 both limiteds with identical immobilizer systems.
The 1999 is my daily driver and the 2000 is a project car/off-road rig that I lost the keys to.
I wasn’t concerned about losing the keys as I don’t drive the car around town and planned on hot wiring it and eventually installing one of those cheap ignition panels from Amazon. I quickly found out it wasn’t that simple.
In order to get the 2000(project) running I installed my 1999’s(daily driver) ecu and put my 1999’s key in the ignition so that it could be read. Because the key in the ignition and the code stored on the ecu matched the security system was disabled and at that point I was able to Hotwire the car.
However this set-up isn’t sustainable, because my daily driver is now missing its ecu.
My question is: Can I change the master key’s hex code on my 2000 ecu to match the code on my 1999 ecu, so that my 2000 will accept the keys I have for my 1999.
Reminder that I don’t need the key to actually turn the ignition lock, I just need the transponder inside to match what’s stored on the cars eeprom chip so that the car can be started.
Given my situation, is there any thing else I could do to completely disable the eeprom system on my 2000 ecu? Like flashing it, removing the chip, or all of the components in the system you showed, etc.
I simply have no need for it, and have made it a goal to spend as little money on this car as possible, to include purchasing new programmable keys. Any advice you have would be highly valued.
Thanks your all of your content. There is a great community for 4runners from this generation that has proved to be very knowledgeable and super helpful, but few of them seem very tech savvy. Your expertise is unique.
Great video your an excellent mechanic the dealer ship should higher you to be there head mechanic!!!!
Haha thanks. I'm not a mechanic. Just an engineer with some time on my hands.
I originally bought this car for parts to teardown and make videos on, but I felt bad because this car seemed in such good shape to have a transmission total it.
Sadly, no, he would’ve failed this test as a dealer mechanic.
Their service department did a great job. They charged the customer for a few hours of labor and then got them to buy a new vehicle....I bet they probably hooked it up to their scanner and couldn’t figure it out so said it was a tranny issue and quoted the customer a super high price that scared a stranded customer to buy a new car, even though, like he said, it doesn’t make any sense that a tranny on a Camry would go out with such low mileage and normal fluid.
@@speedkar1005 are you an automotive engineer?
Cool story and I'm digging the format of video. Love to see more like this!
Great job on diagnosis
Thanks
My E39 had the same problem. Cost me $140 to fix. But BMW tells you it's the ABS module. Not the same symptoms as the Camry...only dash light on the BMW.
Nice good diagnostic.
Thanks
Congrats lovely car
Would be nice to see a pic of the other side of the PCB.
Yet another Camry saved from the scrapyard
Dirty dealers, anything for that commission, At least it's in good hands now
Hopefully it works good for me. I sold my 1MZ Camry for this 3MZ Camry with 100,000 less kilometers
In this case I suspect not dirty, just incompetent
@@n0ch91c3s yes, true lol.
So it seems that ABS module ruined the CAN bus messages.
It sent the wrong speed signals to the ECU which messed up the transmission commands
Top notch 👍
once again why you should support right to repair.
Agreed
I would lose my mind if I couldn't repair an issue on my car that I knew how to repair that the stealership technicians couldn't figure out
Hi great information video. Do you reprogram the abs module
No need to reprogram. Just find the correct one that fits, 2003-06 Camry. The 2002 uses a different module.
"Misdiagnosed"
They wanted to sell a car most likely.
Sorry, I'm a cynic.
Love the channels.
Overheated TCM is my first guess at the beginning the video.
Ah ok the abs control module then.
You scored good job
So even if they had changed the transmission it would not solve the problem 😅tnx for video. 👍
good job!

You are my kinda guy
Is this a factory Camry steering wheel? It reminds me of the 2002-2006 ES300
I scored it from the trip to the junkyard from an 04 ES330. Fits beautifully and I love how it feels.
Kept the OEM airbag and the Toyota steering wheel side cover piece fits over the cutout where the steering wheel controls were so it looks legit.
I was thinking the same thing, it looks great!

Don't reverse engineer this 1 till it pops...perfectly fine running 3.3 yoda
Great find👍
Luckily you don’t have the 4cyl Camry, where the head bolts can get stripped out and the head gasket leaks.
Yeah I'd not want to own one of those. Too slow and unrefined
That's a nice win!
Have you ever seen this particular type of failure before?
That looks like a great ride, nice work 👌 the spiral cable still ok?
I miss my xv30
Did you pay for the license to the techstream? because i have the download but not sure if they allow for 30 days free or what..
No. I have an old version. See my techstream video from 2015.
@@speedkar1005 okay thank you.
Could this be similar to what's causing transmission conplaints for the 2019-2020 Acura RDX?
Just out of curiosity how much did you pay for it?
Guess
Imma say 2500?
@@speedkar1005 $500
I have a 2001 Toyota Sienna after I got an accident my ABS light is on all the time and mechanics did not find any codes and they said the computer and the ABS system is not communicating is this wright or why please advise. my van has only 150000 miles on it and I am the original owner
My toyota, at firt start in the morning, Reverse works fine but D takes time to engage with a kick. Any ideas??
Which stealership conned the previous owner? I'm in the GTA as well. PM me if you want. Thanks
Somewhere in Mississauga. That's where the car was at least.
Wait: no old underwear or toothbrush used in this video?
Did you delete some of your old videos?
I moved it to this channel because of monetization issues
Hi my friend. How much for the Camry. I'm in Toronto
Not selling it yet. Still have it
Hi man I have the same 3.3 vvti in my Sienna. It has the ticking/clicking cam gear (intake) that you mentioned in another video. Does yours do it? I really want to replace my cam gears so it will work properly. MPG also went from 19.7 to 18.5. When I look at diagrams the exhaust cam feeds from the timing belt and there are gears, not a chain, that connects the exhaust cam to the intake cam on the back. I’m pretty sure you can remove just the intake cam without messing with the front of the engine. Have you heard anything like that? Either way thanks for the video.
Try using seafoam or an interval of royal purple to clean it out.
A pre lube tank will also fix it
Sometimes lower viscosity oil like 0w20 will fix it although the 3mz is not made for 0w20
May I buy the camery from you
Not selling it. I like the car.
Comes to show that all those fancy computers, and equipment that the dealership has, isn't worth anything to fix a simple solution a car needed.
They just wanted to sell them a new car.
And they did!
👏👏👏
Pretty low mileaage. 218000km. Yeah that's pretty low for a Camry
Hey man,
Do you need an apprentice?
Still don’t get it. What does ABS has to do with transmission?!
Everything…
