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

SYSTEM DESCRIPTION

The main body ECU (multiplex network body ECU) receives the retractable outer mirror switch signal from the retractable outer mirror switch. The main body ECU then sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. Based on the signal, each outer mirror control ECU assembly retracts or returns the outer rear view mirror assembly.

   INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH

   
   
   1. 

      Remove the outer rear view mirror assembly RH (Click here).

   2. When checking each mirror position, set the mirror position by hand. Apply auxiliary battery voltage and check the mirror movement.

      Note:
      

      • Disconnect and reconnect the auxiliary battery for each mirror position check.

      • The mirror position cannot be changed manually when the auxiliary battery is connected. To change the mirror position manually, the auxiliary battery must be disconnected first.

      OK
