POWER MIRROR CONTROL SYSTEM(w/ Memory) Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

DESCRIPTION

When the outer mirror switch assembly mirror retract switch is operated, deploy/retract signals are sent to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends deploy/retract signals to the outer mirror control ECU assembly via CAN communication. The outer mirror control ECU assembly deploys and retracts the outer rear view mirror assembly based on the received signals.

CAUTION / NOTICE / HINT

Note


  • First perform the communication function inspections in How to Proceed with Troubleshooting to confirm that there are no CAN communication malfunctions before troubleshooting this problem.

  • If the main body ECU (multiplex network body ECU) is replaced, refer to Service Bulletin.
