Question about 1997 Pontiac Grand Prix
Recently the car have too many lights on inside
like CHECK ENGINE SOON , ABS, CHECK TIRE PRESSURE, LOW TRAC, im really so confused why these light s coming up?
I suspect that your problem lies within the vehicle's ECC (Engine Control Computer). Prior to replacing it or having it tested, I would try re-setting it. You can do this by pulling the fuse (for good measure) to the ECC and disconnecting the negative battery terminal for thirty seconds.
During the time you have the power disconnected to the ECC, I would go ahead and check all the connections (make sure they're not only connected firmly, but also free of corosion). Electronic connector cleaner and a soft bronze brush (available at electronic supply stores) can be used to clean the connectors if necessary. After cleaning the connection, coat the wire ends with dielectric compound if it was used previously.
I believe the ECC for your vehicle is mounted under the hood on the passenger side wheelwell (front side of the strut tower).
Hope this helps and good luck!
