    INSPECT HAZARD WARNING SIGNAL SWITCH ASSEMBLY (w/o Display)


    1. Check the resistance.


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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        3 - 16 Hazard warning signal switch off 10 kΩ or higher
        Hazard warning signal switch on Below 1 Ω

        If the result is not as specified, there may be a malfunction in the hazard warning signal switch assembly.

    2. Illumination inspection.


      1. A01DTMXE04

        Apply battery voltage to the connector and check the illumination condition.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → Terminal 11 (ILL+)

        Battery negative (-) → Terminal 8 (ILL-)
