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

SYSTEM DESCRIPTION

On receiving a reverse signal from the park/neutral position switch, the power management 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. Each outer mirror control ECU 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).

PROCEDURE


  1. CHECK MEMORY AND REACTIVATION FUNCTION


    1. A01NGERE01
      Text in Illustration
      *1 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 function is normal A
      Memory function is not normal B
      Reactivation function is not normal C

    C

    GO TO OTHER FLOW CHART (Power Mirrors do not Return to Memorized Position) Click here

    A

  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 (P0705)


    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 DTC P0705 is output.

      OK
      DTC P0705 is 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. READ VALUE USING INTELLIGENT TESTER


    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: Body / Master Switch / Data List.

    5. Read the Data List according to the display on the intelligent tester.

      Master Switch
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Mirror Selection SW (R) Mirror select switch R signal / ON or OFF

      ON: Mirror select switch R is on

      		 -
      Mirror Selection SW (L) Mirror select switch L signal / ON or OFF

      ON: Mirror select switch L is on

      OFF: Mirror select switch L is off

      		 -
      OK
      ON and OFF appear on the screen.

    NG

    OK

  6. CHECK REVERSE SHIFT-LINKED FUNCTION


    1. A01NDGV

      Turn the power switch on (IG).

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

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

      Result
      Result Proceed to
      Reverse shift-linked function on both mirrors is 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
