DTC B2965: Key In Ignition Fault: Description

Body Control Module (BCM) monitors circuit No. 80 (Light Green wire) to determine if key is in ignition. DTC B2965 will set if key-in-ignition input is not active after ignition has been on for 20 seconds. When DTC is present, BCM assumes key-in-ignition input is active and interior lights will not turn on after key is removed from ignition switch.
