It is possible the driver's door control module has gone bad, especially if you recently had a broken window regulator in any of the other doors (the cable mechanism that makes your windows go up & down) . My passenger front window regulator mechanism failed and took out my driver's door control module in my 2000 Bonneville. The driver's door module acts as the master controller of the other three door modules which as indicated by the other comments all "talk" to each other. Spent $150 for someone to diagnose that they could not communicate with that module, but they wanted $1150 to replace it as the local dealer wanted about $800 for the part. Online GM sellers wanted over $400 for it. Found a used one on ebay for $25 from a wrecking yard and it solved the problem. Easy to replace myself, just two nuts and four plugs to pull out and put in on the replacement.
This may be a bad rear integrated control module. or connection or wiring to it. REAR INTEGRATION MODULE (RIM) The CTD system is an internal function of the rear integration module (RIM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the RIM detects an unauthorized entry, the RIM sends a message via the serial data circuit to the DIM to activate the horns and exterior lamps. The RIM has 5 basic modes. Disarmed, standby, delayed, armed, and alarm for operating the CTD system. The 5 modes transition from one step to the next in the following order:
When in the disarmed mode, ignition is OFF and any door is open the RIM commands the instrument cluster to flash the SECURITY indicator via the class 2 serial data circuit. The RIM has the CTD system in a disarmed mode until the following conditions are detected:
Ignition key turned to the OFF position Any door open Doors locked by either the power door lock switch or the LOCK button on the keyless entry transmitter
The RIM enters the standby mode when the above conditions are detected. In standby mode the RIM commands the instrument cluster to illuminate the SECURITY indicator via the class 2 serial data circuit. If all the doors are closed and the LOCK button on the keyless entry transmitter is used, the RIM enters the delayed mode. When the last door is closed, the RIM enters the delayed mode for 30 seconds . In delayed mode the RIM commands the instrument cluster to illuminate the SECURITY indicator on steady via the class 2 serial data circuit. After 30 seconds , the RIM enters the armed mode. In armed mode the RIM commands the instrument cluster to turn off the SECURITY indicator via the class 2 serial data circuit. Any forced entry activates the alarm mode.
IMPORTANT: The CTD system can be armed with the windows or sunroof open.
