PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (POWER SOURCE VOLTAGE)


    1. B004FTXC06
      *a

      Front view of wire harness connector

      (to Forward Recognition Camera)

      Disconnect the W18 forward recognition camera connector.

    2. Turn the power switch on (IG).

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      W18-7 (IGB) - Body ground Power switch on (IG) 11 to 14 V

    4. Turn the power switch off.

    5. Connect the W18 forward recognition camera connector.
