  2. CHECK HARNESS AND CONNECTOR (NO. 2 CLUTCH START SWITCH ASSEMBLY - ECM AND BATTERY)


    1. Disconnect the A40*1 or A41*2 No. 2 clutch start switch assembly connector.


      • *1: for LHD

      • *2: for RHD

    2. Disconnect the A59 ECM connector.

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      for LHD
      Tester Connection Switch Condition Specified Condition
      A40-1 - Body ground Ignition switch ON 11 to 14 V
      Ignition switch off Below 1 V
      for RHD
      Tester Connection Switch Condition Specified Condition
      A41-1 - Body ground Ignition switch ON 11 to 14 V
