POWER MIRROR CONTROL SYSTEM Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

The circuit detects the conditions of the outer mirror switch.

The outer mirror switch sends information about the operating condition of the mirror switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the outer mirror control ECU. Mirror adjustment is controlled by the outer mirror control ECU.
