Diagnosis And Testing - Speed Control Switch
WARNING:
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
- Remove the speed control and Blue And Me (if equipped) switch pods from the steering wheel. Refer to SWITCH, SPEED CONTROL, REMOVAL .
- Disconnect the steering wheel switch pod pigtail wire harness connector from the clockspring.
- Using an ohmmeter, test the resistance between the terminals of the switch as shown in the Speed Control Switch Tests table.
