POWER MIRROR CONTROL SYSTEM (w/ Memory) > Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

for Preparation Click here


SYSTEM DESCRIPTION

When the mirror adjust switch is operated, the main body ECU (multiplex network body ECU) detects the switch operation and sends the mirror adjust switch signal to the outer mirror control ECU assembly (driver side) via CAN communication. On receiving the signal, the outer mirror control ECU assembly (driver side) operates the vertical and horizontal mirror motors, which are built into the outer mirror actuator assembly (driver side), to adjust the mirror surface position.
