Power Locks: Notes

The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a scan tool and the proper Diagnostic Procedures information. 

For circuit diagram information, refer to:

• SYSTEM WIRING DIAGRAMS for 300.
• SYSTEM WIRING DIAGRAMS for Charger.

Following are tests that will help to diagnose the hard wired components and circuits of the power lock system. However, these tests may not prove conclusive in the diagnosis of this system. In order to obtain conclusive testing of the power lock system, the CAN data bus network must be checked.
