POWER MIRROR CONTROL SYSTEM Power Mirrors do not Return to Memorized Position

SYSTEM DESCRIPTION

When the seat memory M1, M2 or M3 switch is pressed, the front power seat switch (for driver side) memory's driver and passenger seat mirror position signal is sent through the CAN communication line to the front door ECU LH and RH. The front door ECU LH and RH then activate the mirror control motors to move the mirrors to the previously recorded positions.

  2. CHECK POWER MIRROR CONTROL FUNCTION


    1. Check that the mirror surface positions of the outer rear view mirror LH and RH can be moved using the outer mirror switch.

      OK
      Mirror surface positions of the outer rear view mirror LH and RH can be moved using the outer mirror switch.

  3. CHECK SEAT MEMORY SWITCH FUNCTION (MIRROR MEMORY FUNCTION)


    1. Check that the outer rear view mirror LH and RH positions can be memorized using the seat memory switch.

      OK
      Outer rear view mirror LH and RH positions can be memorized using seat memory switch.
