8N - 32 POWER LOCKS - SERVICE INFORMATION
When trouble shooting problems with the Power Locks System, always verify that the power lock switch is func-
tional. If the doors, rear liftgate, or fuel door do not lock/unlock with the power lock switch, the following system
components should be analyzed:
• Power door lock switch
• Body Control Module (BCM)
• Remote Keyless Entry Relay
• Power Lock/Actuator assemblies
• Sentry Key Remote Entry Module (SKREEM)
• Central Locking Pump/Security System Module
• Pneumatic supply lines
There are three main Electronic Control Modules which are interdependent on each other to complete lock/unlock
commands, they are the BCM, SKREEM, and Central Locking Pump/Security System Module. These modules can-
not be adjusted or repaired. For complete power locks diagnosis procedures, refer to Power Locks Electrical Diag-
nostics in this section.
PNEUMATIC SUPPLY LINES
The Power Lock Actuators are controlled by pneumatic supply lines that transfer either vacuum or pressure from the
Central Locking Pump/Security System Module to the component through distributors. When trouble shooting prob-
lems related to the pneumatic portion of the power lock system, a preliminary inspection should be performed to
determine that the pneumatic supply lines and harness connectors are free from kink or blockage damage. If nec-
essary, repairs to the pneumatic supply lines or harness connectors must be performed first before proceeding with
additional Power Lock System diagnosis.
