Power Foldaway Mirror Test

The most reliable, efficient and accurate means to diagnose the power mirror system requires the use of a DRB scan tool and the proper Diagnostic Procedures. The DRB 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, that the power mirror motors are being sent the proper hard wired outputs, and that the mirror position potentiometers are returning the proper outputs to the door modules for them to perform their power mirror system functions.
