POWER MIRROR CONTROL SYSTEM (w/ Memory) Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

The main body ECU (multiplex network body ECU) detects the mirror adjust switch status and sends the signal to the outer mirror control ECU assembly via CAN communication. On receiving the signal, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors to adjust the mirror surface position.

      (Outer Mirror Switch Assembly)

      Remove the outer mirror switch assembly Click here.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      H136-8 (M+) - H136-6 (E) Mirror adjust switch pressed up 90 to 110 Ω
      Mirror adjust switch pressed down 437 to 503 Ω
      Mirror adjust switch pressed left 744 to 856 Ω
      Mirror adjust switch pressed right 225 to 275 Ω
      H136-3 (MSW) - H136-6 (E) Mirror select switch R Below 10 Ω
      Mirror select switch L 90 to 110 Ω
      Mirror select switch off 10 kΩ or higher

    NG

    OK

  4. CHECK HARNESS AND CONNECTOR (OUTER MIRROR SWITCH - MAIN BODY ECU)


    1. Disconnect the H17 connector from the main body ECU (multiplex network body ECU).

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
