Diagnosis And Testing - Driver Power Seat Track: Notes
WARNING: This page is about a different car, the 2004 Chrysler Pacifica. 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 seat track requires the use of a DRB III(R) scan tool and ELECTRONIC CONTROL MODULES . The DRB III(R) scan tool can provide confirmation that the PCI data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus network, and that the power seat system is receiving the proper hard wired inputs and relaying the proper hard wired outputs to perform its functions.
Following are tests that will help to diagnose the hard wired components and circuits of the power seat system.
