Air bag warn light Engine warn light Car runs great . Why are these signals coming up on the dash ?

Try getting out of the car, close the door, lock it with the remote.
Then, open the door using the KEY and try to start the car.

Un hook battery and let sit for 30 minutes with no power. This should let the capacitors bleed down and reset the code. It probably has a lost power code that is being retained memory.

ignition switches are common problems for this model

Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

Saw this in many Buicks while working valet 7+ years, has to be some kind of recall. I suggest calling a dealer

1. There is a recall on the clock!!!

2. The 2 codes you have, lead me to the Transmission Control modual, Is there a 3rd code with those 2?? If so it would narro it down for me

3. From all my reserch for the air bag it leads to the Air Bag Diagnostic Unit, about $200.00, on line. Dealer cost is $240.00 plus labor. If under warrenty, they dont want to change...and eat the cost..

There is also a control modual under dash behind heater controls...which has something to do with the clock and a few other things???? Have not had the chance to get into it????

Hi A J Mae,
Do you mean the traffic indicators,( turn signals) or do you mean the dash board indicator lamps? If it's the dash warning lamp indicators, they work on a fail safe system, when you turn the ignition on before the start position, all the lights will come on untill start up and ten they will go off automatically within a second or two....if they stay on with the engine runnig you have a problem we have not covered here.
That will be your hazard warning switch, the one that will be flashing on the dash with a triangle showing on it....If that doesn't do it it'll be something to do with the anti theft device...get out of the car lock all the doors and then press the button on the key fob

I have a similar problem with my 94 concorde... and was advised the on board computer was in need of replacement. Further research led to pulling the computer and cleaning the ground connection to the chassis. It will sometimes leak under the computer and corrode, and compromise the ground, which in turn will cause faulty "code" readings and the engine control light to come on.
