POWER MIRROR CONTROL SYSTEM Reverse Shift-linked Function of Power Mirrors does not Operate

DESCRIPTION

The ECM sends the reverse signal to the main body ECU (multiplex network body ECU) via CAN communication. When receiving the reverse signal, the main body ECU (multiplex network body ECU) sends the reverse request signal to each front multiplex network door ECU. Based on the signal, each front multiplex network door ECU then performs control.

CAUTION / NOTICE / HINT

Note


  • The power mirror control system (w/ Memory) uses the CAN communication system. First, confirm that there is no malfunction in the CAN communication system. Refer to the How to Proceed with Troubleshooting procedure.

Tech Tips

The reverse shift-linked function will not activate when both the mirror select switch L and R switch are off.

PROCEDURE


  1. CHECK MEMORY AND REACTIVATION FUNCTION


    1. B002EUAC13
      *a Turn to Fully Left Position

      Turn the engine switch on (IG).

    2. Using the power window regulator master switch assembly, turn the mirror surface to the fully left position.

    3. Press the M1 switch while the SET switch is being pressed.

    4. Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.

    5. Using the power window regulator master switch assembly, turn the mirror surface to the fully right position.

    6. Press the M1 switch.

    7. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the memorized fully left position.

      Result
      Result Proceed to
      Memory and reactivation functions are normal A
      Memory function is not normal B
      Reactivation function is not normal C
