Component Testing
WARNING: This page is about a different car, the 2007 Saturn Sky. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Refer to SIR Caution
.
Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to Sir Disabling And Enabling .
IMPORTANT:
The cruise control ON/OFF switch must be ON in order to properly measure the resistance of the - SET and the + RES switches.
- Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
- Ignition OFF, disconnect C3 at the inflatable restraint steering wheel module coil.
- 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 on the schematic for the ON/OFF, -SET, and the + RES switches.
- If any of the resistance measurements for the OFF, ON, -SET, and the + RES switches are not within the listed resistance values, replace the cruise control switch.
Cruise Control Inoperative/Malfunctioning
| Function Switch | Minimum Resistance Value | Maximum Resistance Value |
|---|---|---|
| OFF | O.L. | O.L. |
| ON | 7.8k Ohms | 8.6k Ohms |
| - SET | 2.7k Ohms | 3.0k Ohms |
| + RES | 1.2k Ohms | 1.3k Ohms |
