Removal and Installation

  1. Disconnect the negative battery cable.

    Tightening Torque: 4.0 ~ 6 N·m

  2. Remove the driver airbag module. (Refer to RT group - "Airbag Module")
  3. Remove the steering wheel. (Refer to ST group - "Steering Column and Shaft")
  4. Remove the steering wheel cover (A) after loosening the screws.
  5. Loosen the screws on the rear side of the switch.
  6. Disconnect the cruise control switch connector and remove the switch (A).
    Be careful not to damage the hook when removing the switch.
  7. Installation is the reverse of removal.

Inspection

Resistance Measurement
  1. Disconnect the cruise control switch connector from the control switch.
  2. Measure the resistance between the terminals of the control switch when each function switch is in the ON position (switch pressed).
    Function Switch Terminal Resistance
    CANCEL 2 - 7 180? ± 5%
    SET/- 2 - 7 330? ± 5%
    RES/+ 2 - 7 550? ± 5%
    ON/OFF 2 - 7 880? ± 5%
  3. If not within specification, replace the switch.
  4. Connect the cruise control switch connector to the control switch.
  5. With the ignition ON, measure the voltage between the terminals of the harness-side connector when each function switch is in the ON position (switch depressed).
    Function Switch Terminal Voltage
    CANCEL 2 - 7 0.67 ~ 0.86 V
    SET/- 2 - 7 1.10 ~ 1.39 V
    RES/+ 2 - 7 1.59 ~ 1.97 V
    ON/OFF 2 - 7 2.13 ~ 2.56 V
  6. If not within specification, inspect the control switch resistance. If the measured resistance is not within specification, replace the switch and measure the voltage again.
  7. If the resistance is normal but the measured voltage is not within specification, inspect the harness and connectors between the switch and the instrument cluster.
