Mirror Switch Circuit
DESCRIPTION
The remote control mirror switch has different levels of resistance depending on the switch position.
The main body ECU senses the switch position through the resistance of the remote control mirror switch. The main body ECU sends an up/down/right/left signal to the driver door ECU and the passenger door ECU via BEAN.
The mirror's driving position and retract position are directly controlled by the remote control mirror switch.
INSPECTION PROCEDURE
HINT: When using the intelligent tester, start the inspection from step 1 and when not using the intelligent tester, start from step 2.
