Reversible actuators control the power door locks. The Body Control Module (BCM), also referred to as Multifunction Alarm, Lock & Lighting (MALL) module supplies battery voltage and ground when module receives an input signal from a front power door lock switch.
Each door lock actuator contains an electronic circuit breaker which opens to protect actuator from damage when door lock actuator is overloaded. Circuit breaker will reset when voltage is removed from actuator.
The Automatic Door Lock (ADL) operation is controlled by the Body Control Module (BCM). ADL operation can be customized. See SYSTEM CUSTOMIZATION. BCM/MALL unlocks all doors when pressing UNLOCK once on either front door lock switch.
