Component Testing
WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
The cruise control switch must be ON in order to properly measure the resistance of the - SET, + RES or Cancel switches.
- Ignition OFF, disconnect the harness connector at the steering wheel controls switch - left.
- Measure the resistance between terminals 1 and 3 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 switch - left.
| Function Switch | Minimum Resistance Value | Maximum Resistance Value |
|---|---|---|
| OFF | O.L. | O.L. |
| ON | 6.6K Ohms | 7.0K Ohms |
| -/SET | 2.1K Ohms | 2.5K Ohms |
| +/RES | 3.6K Ohms | 4.0K Ohms |
| Cancel | 1.3K Ohms | 1.7K Ohms |
