Cruise Control Inoperative/Malfunctioning 2.0L
Diagnostic Aids
Caution: Refer to SIR Caution in the Preface section.
Disable the inflatable restraint steering wheel module when performing this diagnostic table. Refer to SIR Disabling and Enabling in SIR.
| • | Ensure that the following cruise control switches are not stuck in the engaged position: |
| - | On/off switch |
| - | Set/coast switch |
| - | Resume/accel switch |
| • | With a scan tool, observe the associated cruise control switch parameter in the Powertrain Cruise Control Data list, while rotating the steering wheel to both steering stops and separately activating each cruise control switch. This will help eliminate the possibility of an internally shorted inflatable restraint steering wheel module coil. |
| • | For an intermittent condition, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. |

Cruise Control Inoperative/Malfunctioning 2.2L
Diagnostic Aids
Caution: Refer to SIR Caution in the Preface section.
Important: Perform the following in order to avoid misdiagnosis.
| • | Inspect for proper operation of brake lamps. |
| • | Inspect throttle linkage for mechanical binding which could cause the system to malfunction. |
| • | Inspect cruise control cable adjustment, should have minimum slack. |
| • | When testing vehicles equipped with steering wheel controls, the steering wheel must be rotated to each stop position while testing the cruise control switch signal circuits. This will ensure the integrity of the SIR coil. |
Disable the inflatable restraint steering wheel module when performing this diagnostic table. Refer to SIR Disabling and Enabling in SIR.
| • | Ensure that the following cruise control switches are not stuck in the engaged position: |
| - | On/off switch |
| - | Set/coast switch |
| - | Resume/accel switch |
| • | With a scan tool, observe the associated cruise control switch parameter in the Powertrain General Info-Inputs data list, while rotating the steering wheel to both steering stops and separately activating each cruise control switch. This will help eliminate the possibility of an internally shorted inflatable restraint steering wheel module coil. |
| • | For an intermittent condition, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. |
Conditions for Enabling Cruise Control
| • | When vehicle speed is more than 40 km/h (25 mph) |
| • | When PARK, REVERSE, NEUTRAL, or 1st gear is not indicated |
| • | When an over/undercharged battery condition does not exist |
| • | With normal engine RPM |
| • | Without high engine RPM fuel cut-off |
