Removal and Installation

1. | Disconnect the battery negative terminal.

Tightening torque :
4.0 ~ 6.0N.m (0.4 ~ 0.6kgf.m, 3.0 ~ 4.4lb-ft)

2. | Remove the driver airbag module. (Refer to the RT group - "Airbag module")

3. | Remove the steering wheel. (Refer to the ST group - "Steering column and shaft")

4. | Remove the steering wheel cover (A) after loosening the screws.

5. | Disconnect the cruise control switch connector (A) and then remove the switch.

Be careful not to damage the hook when removing the switch.

Inspection

Measuring Resistance

1. | Disconnect the cruise control switch connector from the control switch.

2. | Measure resistance between terminals on the control switch when each function switch is ON (switch is depressed).

Function switch | Terminal | Resistance
CANCEL | 3 - 4 | 180Ω ± 5%
SET/– | 3 - 4 | 330Ω ± 5%
RES/+ | 3 - 4 | 550Ω ± 5%
ON/OFF | 3 - 4 | 880Ω ± 5%

3. | If not within specification, replace switch.

Measuring Voltage

1. | Connect the cruise control switch connector to the control switch.

2. | Measure voltage between terminals on the harness side connector when each function switch is ON (switch is depressed).

Function switch | Terminal | Voltage
CANCEL | 3 - 4 | 0.76V ± 0.1V
SET/– | 3 - 4 | 1.24V ± 0.15V
RES/+ | 3 - 4 | 1.77V ± 0.2V
ON/OFF | 3 - 4 | 2.34V ± 0.22V

3. | If not within specification, replace switch.
