Cruise Control - Inoperative/Malfunctioning

CRUISE CONTROL INOPERATIVE/MALFUNCTIONING

DIAGNOSTIC AIDS

CAUTION: Refer to SIR Caution in Service Precautions.

Disable the inflatable restraint steering wheel module when performing this diagnostic table. Refer to SIR Disabling and Enabling Zone 3 in Restraint Systems.

Perform the following in order to avoid misdiagnosis:
- Inspect for proper operation of the brake lamps.
- Inspect for proper adjustment of the TCC/cruise control release switch, if equipped with automatic Transmission.
- Inspect for proper operation of the clutch system, if equipped with manual transmission.
- Rotate the steering wheel to both steering stops while testing the steering wheel control switches. This will eliminate the possibility of a internally open or shorted inflatable restraint steering wheel module coil.

EMI on the speed sensor signal circuit may cause erratic cruise control operation.

For an intermittent condition, refer to Testing for Intermittent and Poor Connections in Diagnostic Aids.
