POWER MIRROR CONTROL SYSTEM Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

This circuit detects the conditions of the mirror control switch.

The outer mirror switch assembly sends information about the operating condition of the mirror switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the front door ECU (for driver side). Mirror adjustment is controlled by the front door ECU (for driver side).

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK DTC


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

      Result:
      Result Proceed to
      CAN DTC is not output A
      CAN DTC is output (for LHD) B
      CAN DTC is output (for RHD) C

  2. READ VALUE USING INTELLIGENT TESTER (MIRROR MASTER SWITCH AND MIRROR CONTROL SWITCH)


    1. Check the Data List for proper functioning of the mirror master switch and mirror control switch.

      D-SEAT SW:
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Mirror selection SW (Left)*1 Mirror master switch signal for LH mirror / ON or OFF

      ON: Mirror master switch is in L position

      OFF: Mirror master switch is OFF or in R position

      		 -
      Mirror selection SW (Right)*2 Mirror master switch signal for RH mirror / ON or OFF

      ON: Mirror master switch is in R position

      OFF: Mirror master switch is OFF or in L position

      		 -
      Mirror Adjustment Right Mirror control switch signal (RIGHT) / ON or OFF

      ON: RIGHT switch is ON

      OFF: Any switch except RIGHT is ON or all switches are OFF

      		 -
      Mirror Adjustment Left Mirror control switch signal (LEFT) / ON or OFF

      ON: LEFT switch is ON

      OFF: Any switch except LEFT is ON or all switches are OFF

      		 -
      Mirror Adjustment Up Mirror control switch signal (UP) / ON or OFF

      ON: UP switch is ON

      OFF: Any switch except UP is ON or all switches are OFF
