Power Mirror System: Notes
NOTE:
Manufacturer recommends using DRB scan tool to check power mirror system. If DRB scan tool is not available, the following tests can be used to diagnose hard-wired components of power system, but results may be inconclusive. In order to obtain conclusive testing of power mirror system, Programmable Communications Interface (PCI) data bus network and all modules that provide inputs to, or receive outputs from power mirror system, must be checked.
