HAZARD WARNING SWITCH INSPECTION

PROCEDURE


  1. INSPECT RADIO RECEIVER ASSEMBLY (w/ Navigation System)


    1. A01R9ICC03
      *a

      Component without harness connected

      (Radio Receiver Assembly (Hazard Warning Signal Switch))

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J54-9 (HAZ) - J50-12 (GND1) Hazard warning signal switch off 1 MΩ or higher
      Hazard warning signal switch on Below 125 Ω

      If the result is not as specified, replace the radio receiver assembly (hazard warning signal switch).

    2. A01R9ICC05
      *a

      Component without harness connected

      (Radio Receiver Assembly (Hazard Warning Signal Switch))

      Hazard warning signal switch indicator inspection


      1. Apply battery voltage to the radio receiver assembly (hazard warning signal switch) and check that the hazard warning signal switch indicator illuminates.

        OK
        Condition Specified Condition

        Battery positive (+) → J54-10 (LJB)

        Battery negative (-) → J50-12 (GND1)

        		 Illuminates

        If the result is not as specified, replace the radio receiver assembly (hazard warning signal switch).

  2. INSPECT RADIO RECEIVER ASSEMBLY (w/o Navigation System)


    1. A01RCCRC01
      *a

      Component without harness connected

      (Radio Receiver Assembly (Hazard Warning Signal Switch))

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J49-4 (HAZ) - J52-7 (GND1) Hazard warning signal switch off 1 MΩ or higher
      Hazard warning signal switch on Below 125 Ω

      If the result is not as specified, replace the radio receiver assembly (hazard warning signal switch).

    2. A01RCCRC02
      *a

      Component without harness connected

      (Radio Receiver Assembly (Hazard Warning Signal Switch))

      Hazard warning signal switch indicator inspection


      1. Apply battery voltage to the radio receiver assembly (hazard warning signal switch) and check that the hazard warning signal switch indicator illuminates.

        OK
        Condition Specified Condition

        Battery positive (+) → J49-7 (LJB)

        Battery negative (-) → J52-7 (GND1)

        		 Illuminates

        If the result is not as specified, replace the radio receiver assembly (hazard warning signal switch).
