Diagnosis And Testing - Passenger Power Seat Track: Notes

The most reliable, efficient, and accurate means to diagnose the power seat system 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, system functions.

Following are tests that will help to diagnose the hard wired components and circuits of the power seat system. However, these tests may not prove conclusive. In order to obtain conclusive testing of the power seat system, the Programmable Communications Interface (PCI) data bus network and all of the electronic modules that provide inputs to, or receive outputs from the system components must be checked.
