POWER MIRROR CONTROL SYSTEM (w/ Retract Mirror) - Power Mirror Surface Position is not Memorized


SYSTEM DESCRIPTION

When the seat memory switch is operated, the switch input signal is sent via CAN communication from the outer mirror control ECU assembly LH*1, RH*2 to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then sends the memorization request or recall request signals to the outer mirror control ECU assembly LH and outer mirror control ECU assembly RH via CAN communication. The outer mirror control ECU assembly LH and outer mirror control ECU assembly RH memorize the mirror position when a memorization request signal is received, and move the mirror to the memorized position when a recall request signal is received.

INSPECTION PROCEDURE

NOTICE:
  1. 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 (Click here).
  2. If the main body ECU (multiplex network body ECU) is replaced, refer to the Entry and Start System (for Entry function) (Click here).
1.CHECK OUTER REAR VIEW MIRROR ASSEMBLY FUNCTION (MANUAL OPERATION FUNCTION)

  1. Check that the mirror operates (Click here).

    OK:
    Mirror operates normally.
