WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. 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 and the + 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 |
