I can think of 3 ways to accomplish this:- 1) Use a “Code Reader” with Re-Set capability. 2) Use a “Scan Tool”. Check out Pep Boys, Cragen, etc for a loaner at low/no cost. 3) Disconnect the negative battery lead for about 60 seconds. # 1 & 2 will provide you with the reason for any trouble codes. # 3 will completely reset the computer and it will have to re-learn it’s trim settings. Also it will remove any programmed radio stations. Regards from C-F
I was told it is a computer issue. Try Disconnecting the battery for about 30 minutes to reset the computer, then reconnect. This has worked on my wife's 2005 300c and my sons 2004 dodge dakota.
Not necessary. The computer will reset itself after a few driving cycles.
I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).
You need a scanner to reset it, driving won't do it. If you reset it and don't fix the problem, the light will come back on in 25 miles. This may or may not work for you-on some cars disconnecting the battery will clear all codes.
You can reset the on board diagnostic computer by disconnecting the battery however if you did not fix the emissions problem it will come back on after driving for a short time. Depending on the faulty component it could light up after a few minutes or a few days
Usually, disconnecting the battery cable is what resets your car's computer(s) ... typically reverting to "default" settings and (sometimes) clearing any trouble codes. Generally, there's no need to do anything after you've reconnected the battery. Some cars have "learning" modes that adjust various settings based on your driving style, and it might take some time for the computer to re-learn everything. But there shouldn't be a big difference. A few cars have language display settings (German/English, for example) that "toggle" from one to the other each time the battery is disconnected. The owner's manual should explain how this works.
This light indicates that you have an emissions contol problem, if the engine is not running poorly or if the vehicle is driving normally it may just be a sensor. Usually you will cause no further damage by driving your car. Inorder to properly diagnose your car you will need to have a technician read the code stored in the engine computer and diagnose it. ... you can try disconnecting the battery for one min. then reconnect the battery. (this in most cases will reset the computer) then drive tha car and see what happens... Good luck.
No. Just reconnect the battery and let the car idle for 5-10 minutes and then start driving the car. The car will relearn your driving habits after a week or two. . . .
Changing the battery will not make the light come on. The computer will automatically recalibrate itself after a few driving cycles. If the check engine light is on, you have a problem with the emissions system. Have the computer scanned with an OBD2 scan tool.
I'd check your alternator. Disconnecting the positive terminal while the engine is running will tell you. If the engine dies when you disconnect the battery, it's your alternator. If it keeps running it's something else, like your battery. I had the same problem.
My MX3 1993 idle dropped to almost stalling point when I stepped on the brake. After replacing the batter this problem disappearred and has so for 2 months now. There was no indication i needed a battery when i was driving it daily,however after leaving it sit for 5 days when I went to start it there was little juice to fire it up. By replacing/disconnecting the battery it reset the computer and I have not had an issue since...worth a try. Chuck
