Component Testing
WARNING: This page is about a different car, the 2007 Chevrolet Malibu. 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 ON, - Set/Cruise, and the + Resume/Accelerate switches.
- Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Non-SS) or Inflatable Restraint Steering Wheel Module Replacement (SS) .
- Ignition OFF, disconnect the cruise control harness connector at the inflatable restraint steering wheel module coil.
- Measure the resistance between terminals E and F (E and H for the Cancel Switch) 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, the + RES, and the Cancel switches.
- If any of the resistance measurements for the OFF, ON, - SET, + RES, and Cancel switches are not within the listed resistance values, replace the cruise control switch assembly.

| OFF | O.L. | O.L. |
| ON | 7.8K ohms | 8.6K ohms |
| - SET | 1.2K ohms | 1.3K ohms |
| + RES | 2.7K ohms | 3.0K ohms |
