Diagnosis And Testing - Power Locks: Notes

WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a DRBIII(R) scan tool and POWER POOR LOCKS/RKE .

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 Programmable Communications Interface (PCI) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the power lock system components must be checked.

The instrument cluster will set Diagnostic Trouble Codes (DTC) for the power lock system.
