Often if battery fails or is disconnected for a time the car will want to have readiness reset. this is best done by a tech using vadcom or vcds software , however alot of the times if there are no other problems ,taking the car for a ride for a bit will let it set readiness on it's own. let car see road speeds from 0 to about 55 mph and give it a few key cycles while driving, meaning ,stop ,park car, turn off ignition and then restart and continue driving. if it doesn't reset within 15 min or so it most likely will have another problem so watch for the mil light to come on during drive. good luck

My tcs light on,high rpm , wont shift in overdrive/ is it a sensor in tranny

I also have a 1999 El Dorado, with 188,000 miles. First my TCS light came on once because I was really racing the car. The car's system went into "reset mode" turning off all of the car's computer controlled functions, Starting with TCS, A/C, ABS etc. This was due to the battery or alternator failing to supply enough electrical current under extreme demands for power and performance. I ultimately had to replace my alternator $450.00. Second, I had a "Check Engine" light on because my transmission was not shifting at the proper times. The computer had to be reprogrammed then the shift pattern was fine.

You should check to see if you car's alternator is working properly by starting the car then disconnection the battery cables while it is still running. If your car still runs, then your alt is okay.
I would also have the transmission's program codes checked and reset if necessary to shift at the right time. When they hook one of those Caddy scopes to your car's main computer, it spits out a series of codes. I do not know how to read the codes, I just know that they can be changed to make the car's performance better. I hope this was helpful.

Hi i bought a vw beetle was running fine the last few days. I went to drive it yesterday and it wont start the immobiliser is showing its not flashing tho. My step dad replaced the car keys battery the day...

My immobiliser keeps flashing until I put the key in the ignition and then it stops. Normally changing key batteries has a period that if the battery is changed inside that time (say 5 minutes) then the key program will not loose memory Run fault codes to see if there is a problem in the electronics. Otherwise you may have to take the car to the dealer to have the key reprogrammed to the cpu in the car

My 316ti compact wont lock with the remote, if it is not the key then what next?

Depending on the age of the car.. it may simply be the battery in the key.

You can either buy a new key.. or pry open the key and replace the 5 dollar battery.. you need to be handy with a soldering gun..

Before you do this.. you can try reprogramming the key..

1:Get in the car and close all of the doors.

2: Turn key on (1st position), and wait for all the lights to go out before turning ignition off. (or under five seconds)

Perform next steps within 30 seconds.

3: Press and hold the UNLOCK button on the key.

4: While still holding the UNLOCK button, press and release the LOCK button three times. Do this deliberately, not too quickly.

5: Release the unlock button. Car's locks should cycle, indicating the key is programmed.

6: On some cars, all keys are cleared from memory, so you will need to repeat steps 2-4 for any other keys.

7: Once all keys are programmed, use the last programmed key to turn the ignition on and back off one last time.

If programming more than one key.. Must be done within 30 seconds of completing the above steps.

This is the first step.. next would be checking the receiver ..I believe it is located in or near the rear view mirror on that car.

If you replace the key battery..or the key(s).. you will have to use the above programming steps to get them to work properly.

Best of luck!

When I put my key in the ignition of my 2008 dodge grand caravan, it reads badkey & wont start. what is the problem?

Newer Dodge Vehicles do not have an ignition for a "metal" key. They use the Electronic Key called a FOB with a built in or integrated metal key that is only used to unlock the door. The FOB inserts into a WIN module (Wireless Ignition Module) instead of the normal igition. Reprogramming the vehicle usually does the trick however there has been significant problems with the WIN module and the dealer may have to replace it. The 2010's have a recall on some models. The manual states the keys cannot be reprogrammed. The first and easiest solution might be to try replacing the battery in the FOB (aka key),

How to reset, plug or unplug my engine light on my 2000 dodge caravan?

you may disconnect the battery for a few minutes, but the correct way is to clear it with a scanner. Of course, resetting the light without the proper repairs, its just going to come back on, after the computer runs the tests and it fails.

you shouldnt have to reprogram the ecu but it wont hurt to reset it. To reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer. not sure how much difference it will make but like i said it wont hurn anything.

Volvo Cooling sensor / fan arent working

Take it one step at a time. First, replace the coolant sensor and try to get the car to start WITH the sensor connected. Make sure that you DO NOT use any teflon tape when installing the switch (this will isolate the switch which will not ground it, making it not work). Th computer receives signals from numerous sensors, and makes adjustments according to inputs received. When the computer gets a signal that the car is still cold, it will adjust the fuel/air ratio to make it run richer (more fuel than air). Once the car is running it will run rough due to a improper mixture since the computer is never sensing the car is warmed up since the sensor is unplugged. This will also account for the slow start due to a richer fuel mixture.
