POWER MIRROR CONTROL SYSTEM(w/ Memory) AUTO Power Retract Mirrors do not operate

DESCRIPTION

When the outer mirror switch assembly is set to AUTO (neutral position), an AUTO signal is detected by the main body ECU (multiplex network body ECU). When locking and unlocking all doors with the power switch off, 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.
