B2964 GMC Description
The Body Control Module (BCM) uses a key in ignition input in order to control certain features in the vehicle. These features are in the following systems: Content Theft Deterrent (if equipped), Audible Warnings, and Automatic Door Locks.
The key in the ignition input circuit is grounded when you fully insert the ignition key into the ignition switch. This, in turn, pulls the BCM key in ignition input low.
