Question about 2002 Cadillac Deville

1 Answer

I have a 2002 Cadillac DTS. It randomly dies when

I have a 2002 Cadillac DTS. It randomly dies when idling at stop lights, stop signs, just before backing up, etc. The dashboard service lights are running amok. Some messages that scroll across the screen are "Service Security System", "Service Stability System", "Service Charging System, Battery Not Charging". Fixed lights on the dash that light up include "Traction Control", "Security System" and "Service Engine Soon". The fuel gauge needle will bury itself on empty while driving, then surge back to the correct fuel measurement position. Yesterday it started surging as I was driving it, as if fuel flow was cut off and then restarted. I've taken it to the local Cadillac dealer six times. They said it was a vacuum leak; $700+ in repairs that solved nothing. Then they said it was the battery: $324 and the warning lights came on again as I was driving it home. This morning I took it to a different mechanic, not a dealership, and it wouldn't start after I shut it off. Dead battery, and it's only a week old! They think it's the alternator and I think they are correct. Any other ideas out there?

SOURCE: stability control engaged and my traction contol comes on

 all wheel drive and stability control are a lot alike, in fact you are better off with all wheel drive. 
These vehicles have all four wheel speed sensors and the braking system keeps the speed of all four as close to the same as possible to control slippage. 
Power is decreased to any wheel that is moving faster than the others so optimum traction is obtained. and this may cause this problem.

I have a 2001 Cadillac DTS with the exact same problem. Nobody including the dealer could figure out what was wrong. I replaced all the coils and the problem stopped happening for a while. Eventually I sold the car for parts. Feh! Very disappointed in Cadillac.

Ok so I changed out the throttle position sensor and its made NO difference~my truck is still Idling rough and dieing need some help here please~~


I guess I will start with asking why you changed the crank sensor and the TPS ?
Usually when the engine is stalling at stop signs the problem is a dirty throttle body or a problem with the idle air control valve.
If the check engine light is on it should have a code unless the PCM is failing. I would try another scanner next to make sure the computer does not have any trouble codes.

Set timing mode 1995 cadillac deville


Depending on the trouble codes, it may be the ECM. (computer)
You can have the car scanned for codes or attempt it yourself.
The "set timing mode" is the section of the computer program that you access to change the base timing. It should not show up on the display unless you access it.

Since the transmission in this car is electronically controlled the first thing that must be done is to have the transmission control module scanned for fault codes, that is numero uno.
