POWER MIRROR CONTROL SYSTEM (w/ Memory) - Reverse Shift-linked Function of Power Mirrors do not Operate
DESCRIPTION
A/T models:
After the ECM receives a reverse signal from the park/neutral position switch, the ECM sends a reverse signal to the outer mirror control ECU via the CAN and BEAN communication systems. The outer mirror control ECU activates the mirror motor in response to the reverse signal.
M/T models:
After the main body ECU RH (cowl side J/B RH) receives a reverse signal from the back up light switch, the ECU sends a reverse signal to the outer mirror control ECU via the BEAN communication system. The outer mirror control ECU activates the mirror motor in response to the reverse signal.
