SYSTEM DESCRIPTION
This 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.
WIRING DIAGRAM
INSPECTION PROCEDURE
Use the intelligent tester to check if the CAN communication system is functioning normally.
