Driver Side Power Mirror Cannot Be Adjusted With Power Mirror Switch

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch
- Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

When the mirror adjust switch is operated, the multiplex network master switch assembly detects the switch operation and sends the mirror adjust switch signal to the main body ECU (multiplex network body ECU) via LIN communication. The main body ECU (multiplex network body ECU) then 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 rear view mirror assembly LH, to adjust the mirror surface position.
