RM38T0EC _59 Vehicle Exterior _112292 MIRROR (EXT) _0502811 POWER MIRROR CONTROL SYSTEM J

MIRROR (EXT)  POWER MIRROR CONTROL SYSTEM  Power Retractable Mirrors do not Operate with Power Retract Mirror Switch  


DESCRIPTION

When the outer mirror switch assembly is operated, the mirror retract/return signal is sent to the main body ECU (multiplex network body ECU) and then to power distribution box assembly via CXPI communication.

The power distribution box assembly retracts or returns the outer rear view mirror assemblies based on the signal.
