POWER MIRROR CONTROL SYSTEM Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

This circuit detects the conditions of the multiplex network master switch assembly.

The multiplex network master switch assembly sends information about the operating condition of the mirror switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the outer mirror control ECU assembly LH*1 or RH*2. Mirror adjustment is controlled by the outer mirror control ECU assembly LH*1 or RH*2.

CAUTION / NOTICE / HINT

Note


  • The power mirror control system uses the CAN communication system and LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power mirror control system after confirming that the communication systems are functioning properly (See page ).
