Component Testing
CAUTION:
Refer to SIR Caution
.
Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to SIR Disabling and Enabling .
- Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Equinox) or Inflatable Restraint Steering Wheel Module Replacement (Torrent) .
- Ignition OFF, disconnect the harness connector C277 at the inflatable restraint steering wheel module.
- Measure the resistance between terminals C and D at the cruise control switch side of the connector. Individually activate and hold each cruise control function switch and compare the resistance reading to the values for the On, Off, - SET, + RES and cancel switches.
- If any of the resistance measurements for the On, Off, - SET, + RES and cancel switches are not within the listed resistance values, replace the steering wheel controls-left.
Cruise Control Inoperative/Malfunctioning
| Function Switch | Minimum Resistance Value | Maximum Resistance Value |
|---|---|---|
| Off | O.L. | O.L. |
| On | 6.5k Ohms | 7.1k Ohms |
| - SET | 2.2k Ohms | 2.4k Ohms |
| + RES | 3.7k Ohms | 3.9k Ohms |
| Cancel | 1.4k Ohms | 1.6k Ohms |
