POWER MIRROR CONTROL SYSTEM(w/ Memory) Reverse Shift-linked Function of Power Mirrors does not Operate

SYSTEM DESCRIPTION

On receiving a reverse signal from the shift lever position sensor, the hybrid vehicle control ECU 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 outer mirror control ECU assembly. Each outer mirror control ECU assembly then performs control in response to the reverse signal.

Tech Tips

The reverse shift-linked function will not activate when the mirror select switch is in the neutral position (off).

      *a Turn to Left Fully

      Turn the power switch on (IG).

    2. Using the outer mirror 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 outer mirror 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 recorded 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

  2. CHECK CAN COMMUNICATION SYSTEM


    1. Use the intelligent tester to check if the CAN communication system is functioning normally Click here.

      OK
      CAN communication DTC is not output.

    NG

    GO TO CAN COMMUNICATION SYSTEM Click here

    OK

  3. CHECK FOR DTC


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / Hybrid Control / DTC.

    5. Check if hybrid control system DTCs are output.

      OK
      Hybrid control system DTCs are not output.

    NG

    GO TO HYBRID CONTROL SYSTEM (DIAGNOSTIC TROUBLE CODE CHART) Click here

    OK

  4. CHECK COMBINATION METER ASSEMBLY


    1. Check if the shift position indicator light in the combination meter assembly operates normally.

      OK
      The shift position indicator light indicates the actual shift position correctly.

    NG

    GO TO METER / GAUGE SYSTEM (PROBLEM SYMPTOMS TABLE) Click here

    OK

  5. CHECK REVERSE SHIFT-LINKED FUNCTION

      *a Downward

      Turn the power switch on (IG).

    2. Set the mirror select switch to L or R.

    3. Check that the mirror surface turns downward when the shift lever is moved to R.

      Result
      Result Proceed to
      Reverse shift-linked functions on both mirrors are not normal A
      Reverse shift-linked function on RH side is not normal B
      Reverse shift-linked function on LH side is not normal C
