I had a problem with my Mazda CX5 . The car suddenly stopped starting on occasion, with no apparent reason. The battery was good and the key fob also worked fine. When the car didn’t start sometimes the dashboard acted up like a Christmas tree. Several mechanics looked at the car and couldn’t fix it. Then I found in UA-cam a video with similar problems and was advised to disconnect the battery for about half an hour, connect it again and with the key fob close and open the car once. Then start the car. It worked perfectly. Since I did this trick the car has started every time without a problem. It seemed to be a reset and the problem was probably that one day I left the car on with the door closed for to long and the car turned of automatically after a certain time period. That was the when the starting problems began and got worse over time. Now I know how the resolve this.
I just watched a video from scotty kilmer saying that you actually need a resistor inbetween there to slow down the rate of discharge because discharging a module can damage the sensitive components by causing a surge of power to be released from the capacitors or something. IDK ive never had a problem doing this and i did it on my VW Jetta once.
We were always taught to connect the positive terminal first for safety reasons because if you connect negative first then second positive terminal the spanner or ratchet could short circuit to battery bracket or other earth even a newly charge battery could explode due to gas fumes or even the spanner has been known to weld itself to ground/earth!
My CD player stopped working in my 2005 Dodge Dakota, it wouldn’t spit out the CD. I was just beginning a long road trip, San Diego to Houston, 1,500 miles, and was looking forward to listening to an audiobook about the life of Abraham Lincoln. I tried everything to get the CD out of there even including using needle nose pliers! Nothing worked. Bummer. Months later I had to replace two oxygen sensors in my catalytic converters which required unhooking the negative battery cable. After replacing them I hooked the negative cable up again and it immediately spit out the CD and it has been working just fine ever since! It just needed to be reset.
Plse help me out the jumper cable were did connect from? Are you connecting to something and then you connect to the battery? I like try to my car thats why asking were you connect to the cable and then connect to the battery?
c'est une excellente méthode de réinitialisation qui fonctionne sur toute les voitures thermiques . ma Peugeot 406 hdi refusait de démarrer sans raison logique et après avoir fait cette manipulation elle a démarré au quart de tour !
wait a second: when removing battery leads the correct way i learned is first neg then pos and when repositioning first pos than neg. Have I been taught wrong??
The procedure is wrong. Under no circumstances should you bridge the + and - cables! In the worst case scenario, this will destroy the engine control unit! Disconnecting the ground cable is sufficient. Then turn on the light switch to let the residual current flow away more quickly. After one night, turn off the light switch again and connect the ground cable. Stop the engine and do not accelerate. Let it stand for 5 minutes, while definitely not stepping on the gas! Then drive 70-80km (city, country, highway) so that the control unit relearns all driving conditions. Complete.
@@General813 u overreacting because why did it work perfectly with him? Plus he did it many times before & no problems & many other people as well like myself, at least he showed proof while u showed nothing so until u can prove it then u can compare
I always opt for a thinner wire with clips attached. There's no requirement for a large cable as it's merely a matter of current. I appreciate you demonstrating how to jump them. It feels like I'm consistently suggesting this action to fellow BMW enthusiasts.
For all you people asking what do I do with the other end of the jumper. Look this isn't rocket science! If you're using jumper cables you will have a red and a black claw like clamp on each end of the jumper cables. So just use the red side of the jumper cable hook one end to the negative battery cable and the other end to the positive.
Yes, I spotted that right away! It's like a never-ending circuit with the single cable connected to positive and negative cables. Never would I have thought of this! However, I have always connected the positive cable first to the battery and then the negative. Had a battery explode one time and don't care to do THAT ONE again!
sometimes the car has a problem and adjusts itself because of said problem (you get an error code and maybe a light on the dash) and runs poor because of it. bad coolant. old oil. old gas or diesel. bad fuel filter. bad air intake. bad sensor. bad pump. then you go fix or maybe just clean it and it still runs poor because the car didn't adjust itself back. by resetting it you basically start with the factory settings. it doesn't "fix" it but it's like retraining memory or restarting a computer. sometimes it just need a fresh new start and if it goes back to running like shit then you need to look at it again.
Would you mind explaining the jumper leads more? I cant see which of the ends and/or negative and positive you used. Video was very informative. 2011 BMW F25 i28 xdrive. Thank You!!!
It might clear the warning, but it probably won't fix the real problem. Plus the code will stay in the cars computer. Also on some cars you'll need to recode the radio, and even re set the electric windows. Some Ford's have this issue.
I did this with a 1991 730se after it was stuck in 2nd (limp mode) 20 years ago ,after putting a second hand autobox in her i took the battery out put a jump lead between the plus and minus charged the battery, left the jumplead on for like 2 weeks ,fired her up and bingo all 4 gears,fun fact same gearbox as a range rover,just without the transfer box a HP4 something like that,i did all this in 2004/5😂
Whats on the other end of the jumper leads ??. You dont explain if the jumpers are connected to anything ??. Or do you just use 1 lead and attach it the the negative and the other end of the lead to positive ???. Max.
Hello I tried this on my very old 2002 renualt clio and yes it worked a treat idling was a mess I think it reset the airflow and sparkplugs and everything that go's along with it thank you so much
not true exactly. it will reset, but DTC will stay memorised.. you need diagnostic equipment to read and delete fault codes and that is only and proper way to remove all DTC after repair.
I think the last time you presented this, you turned on the headlights for a moment while the leads were connected to discharge any electricity that might be in the system.
I had a problem with my van not starting. When I got it going it was fine. But if I stopped somewhere and tried to start it again. It wouldn't start again. Thought the battery was dead. After a while it wouldn't even turn over but there was still power in the battery. Took a look under Neath on a lift . Get this it turns out the connector wire for the starter was loose and came off.
Thxs for the video I will try it, but I have one question, do I use a single jump cable and connect one end to + and the other end to -? To create some kind of circul connection?

Thanks Dean, I understand the theory behind this, it clears the memory and fuel adaptations so to speak. I have tried this and my R53 ran fine for a few hundred miles, and the fault came back. My guess is by clearing the fuel adaption memory the engine was happy, but while driving, the ECU is finding something that it isn't happy with and then readjusting the fuel adaptation. If the engine still pulls good and runs good, would you go down the route of a sensor problem or mechanical.
Instructions are not very clear. Always disconnect & REMOVE the Earth/Negative cable 1st! That way your wrench can not cause a short when touching & disconecting Live / Positive cable!. ALSO! why does Dr. not explain what to do with the 2 clamps on the other side of jumper cable ? CONNECT ?

For a V8 I would say 650rpm would be the best as at 600 all cylinders won’t be balancing correctly I would raise the idle which you can do easily with a scan tool to 650 and see the difference much better on a V8 at 650rpm anything else if it’s 3.0 600rpm is enough

when connecting battery, first connect positive and tighten it, then connect negative, if you connect negative 1st, when connecting positive you can accidentally touch ground of car with your wrench and have short circuit. if you connect positive 1st, when touching with wrench chassis of car, nothing will happen..
It seems there are a FEW thickos on here... let me explain.... 1 jump lead required...1 end to the positive lead and the other one to the negative....FFS ...Although as explained by some of the clever people , it might fuck up your car completely.
