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

        Standard Voltage
        Tester Connection Condition Specified Condition
        1A-8 - Auxiliary battery negative (-)

        Auxiliary battery positive (+) → 1A-1

        Auxiliary battery negative (-) → 1A-7

        		 11 to 14 V

        If the result is not as specified, replace the No. 1 integration relay.

      2. A01MH82C05
        *a

        Component without harness connected

        (No. 1 Integration Relay)
