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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        A50-7 (B) - A50-2 (GND) Ignition switch off 11 to 14 V
        A50-6 (B) - A50-2 (GND) Ignition switch ON (IG) 11 to 14 V

        If the result is not as specified, repair or replace the wire harness.
