        Battery negative (-) → 1D - 7

        		 Below 1 Ω

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

    3. Inspect the HORN relay resistance.


      1. A0049EXC01
        *a

        Component without harness connected

        (No. 1 Integration Relay)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1E-7

        Battery voltage not applied between

        1C-1 - 1D-18 terminals

        		 10 kΩ or higher

        Battery positive (+) → 1E - 10

        Battery negative (-) → 1D - 18

        		 Below 1 Ω

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