Question about 2005 Chevrolet Equinox
I have a 2005 Chevrolet Cobalt, I had to replace the Body Control Module as it got wet and shorted out. (Light flood) The radio is locked which is one problem, but the biggest issue is that I believe that the Theft Lock feature will not allow the car to start. Everything other that the radio works fine, the ignition seems to work fine, but when I turn the key to start the car, it does not crank and the security lock light comes on in the dash. The battery is fully charged, and I can jump across the starter and the engine will crank fine. It might have been a mistake, but I tried using a remote start button on the starter while the key was on, the engine would start run about 10 seconds and die.
If the BCM has been replaced, the BCM has to be reprogrammed by a dealer as it control many car functions.

The ignition is in the ON position.
The vehicle is shifted out of PARK.
The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.
