DYNAMIC RADAR CRUISE CONTROL SYSTEM Distance Control Switch Circuit

DESCRIPTION

The distance control switch sets the vehicle-to-vehicle distance setting. The distance control switch is installed in the steering pad switch. The vehicle-to-vehicle distance setting can be changed by operating the distance control switch in the steering pad switch while the dynamic radar cruise control system is in operation.

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT SPIRAL CABLE SUB-ASSEMBLY


    1. Remove the spiral cable sub-assembly Click here.

    2. A0095SPE03

      If there are any defects as follows, replace the spiral cable with a new one: scratches, cracks, dents or chips in the connector or spiral cable.

    3. Check the spiral cable.


      1. Set the spiral cable to the center position Click here.

      2. Rotate the spiral cable 2.5 times clockwise and measure the resistance according to the value(s) in the table below. Then rotate the spiral cable 5 times counterclockwise and measure the resistance according to the value(s) in the table below.

        Note

        As the spiral cable may break, do not rotate the spiral cable more than the specified amount.

        Standard Resistance
        Tester Connection Condition Specified Condition
        4 (DIST) - 11 (DIST) Always Below 1 Ω
        6 (ECC) - 2 (ECC)

      3. Set the spiral cable to the center position and rotate the spiral cable 2.5 times clockwise. Then, while rotating the spiral cable 5 times counterclockwise, measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        4 (DIST) - 11 (DIST) Always Below 1 Ω
        6 (ECC) - 2 (ECC)

    NG

    REPLACE SPIRAL CABLE SUB-ASSEMBLY Click here

    OK

  2. INSPECT STEERING PAD SWITCH ASSEMBLY (DISTANCE CONTROL SWITCH)


    1. Remove the steering pad switch assembly Click here.

      A0097CDE02

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      4 (DIST) - 6 (ECC) Distance control switch on Below 2.5 Ω
      Distance control switch off 1 MΩ or higher

    NG

    REPLACE STEERING PAD SWITCH ASSEMBLY Click here

    OK

  3. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - DRIVING SUPPORT ECU AND BODY GROUND)


    1. Disconnect the G40 spiral cable connector.

    2. Disconnect the G119 ECU connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G40-11 (DIST) - G119-7 (MODE) Always Below 1 Ω
      G40-2 (ECC) - Body ground
      G40-11 (DIST) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
