Body Control Module General Descriptions: Anti-Lockout
The anti-lockout feature aids in preventing the customer from locking their car keys in the vehicle. This is a programmable feature using the Tech 2. The options are enable and disabling the feature. The feature works as follows: If the keys are in the ignition, and a manual door lock switch is activated with any door open, the BCM will lock all doors, then within 500 ms. the drivers door will unlock. This feature can be overridden in two ways:
- The doors will lock if a lock command from a Remote Keyless Entry (RKE) transmitter is sent to the BCM.
- Manually push the lock tab on the door.
