ELECTRIC PARKING BRAKE SWITCH INSPECTION

PROCEDURE


  1. INSPECT ELECTRIC PARKING BRAKE SWITCH ASSEMBLY


    1. Check the resistance.


      1. A005NUBC09
        *a

        Component without harness connected

        (Electric Parking Brake Switch Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        6 (LOK1) - 2 (GND1) ON (Lock) 2.2 Ω
        Switch not operated 104.8 kΩ
        3 (LOK2) - 2 (GND1) ON (Lock) 1.1 Ω
        Switch not operated 5.8 Ω
        5 (RLS1) - 2 (GND1) OFF (Release) 1.1 Ω
        Switch not operated 5.8 Ω
        4 (RLS2) - 2 (GND1) OFF (Release) 1.1 Ω
        Switch not operated 5.8 Ω

        If the result is not as specified, replace the electric parking brake switch assembly.

    2. Check the Illuminates.


      1. A005NUBC07
        *a

        Component without harness connected

        (Electric Parking Brake Switch Assembly)

        Apply auxiliary battery voltage to the electric parking brake switch assembly and check that the switch illuminates.

        OK
        Condition Specified Condition

        Auxiliary battery positive (+) → Terminal 7 (ILL+)

        Auxiliary battery negative (-) → Terminal 1 (ILL-)

        Illuminates

        If the result is not as specified, replace the electric parking brake switch assembly.
