Cadillac Repair/1991 cadillac service ccr


how do i turn off the ccr service light  on the info. screen


This is or the command control ride. You can't just "turn off" the light. You are dealing with a rear suspension problem. If you did connect the battery like some people try, the light will go out momentarily, but will come right back on. This is telling you that either the air compressor on the driver's side inner fender is not functioning, or the struts in the rear suspension are leaking. Something is wrong with the rear suspension and the height control. For more articulate information on diagnoses and repair, I would recommend trying to obtain a factory service manual from Ebay or craigs list.
You will find that the manual will assist you many times over i diagnosing and repairing problems in the vehicle.
Everything is integrated in the vehicle and is linked to the computer. When the computer sees an issue, one cannot turn off a light.
This may be something simple like a blown fuse or a loose airline to a rear strut.

It is a common complaint though and all you need to do is google 1991 Cadillac CCR to see that.

Good luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
