PROCEDURE


  1. INSPECT STOP LIGHT SWITCH ASSEMBLY


    1. A01CPXAC10
      *a

      Front view of wire harness connector

      (to Stop Light Switch Assembly)

      Disconnect the stop light switch assembly connector.

    2. Measure the voltage and resistance on the wire harness side connector according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      A1-1 (B) - A1-3 (GND) Always 11 to 14 V
      A1-5 (B) - A1-3 (GND) Always 11 to 14 V
      Standard Resistance
      Tester Connection Condition Specified Condition
      A1-3 (GND) - Body ground Always Below 1 Ω

      If the result is not as specified, repair or replace the wire harness or connector.

    3. Reconnect the stop light switch assembly connector.

    4. A01CN0SC11
      *a

      Component with harness connected

      (Stop Light Switch Assembly)

      w/o Dynamic Radar Cruise Control System:

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A1-2 (L) - A1-3 (GND) Brake pedal not depressed 0 to 1.5 V
      A1-2 (L) - A1-3 (GND) Brake pedal depressed 7.5 to 14 V
      A1-4 (L) - A1-3 (GND) Brake pedal not depressed 7.5 to 14 V
      A1-4 (L) - A1-3 (GND) Brake pedal depressed 0 to 1.5 V

      If the result is not as specified, replace the stop light switch assembly.

    5. A01CN0SC11
      *a

      Component with harness connected

      (Stop Light Switch Assembly)

      w/ Dynamic Radar Cruise Control System:

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A1-2 (L) - A1-3 (GND) Power switch off, brake pedal not depressed 0 to 1.5 V
      A1-2 (L) - A1-3 (GND) Power switch off, brake pedal depressed 7.5 to 14 V
      A1-4 (L) - A1-3 (GND) Power switch on (IG), brake pedal not depressed 7.5 to 14 V
      A1-4 (L) - A1-3 (GND) Power switch on (IG), brake pedal depressed 0 to 1.5 V

      If the result is not as specified, replace the stop light switch assembly.
