Circuit/System Verification
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If the condition is intermittent or cannot be duplicated, disconnect the connectors and add Nyogel lubricant 760G. This procedure will correct the high resistance condition due to terminal fretting corrosion.
- Ignition ON.
- Verify the scan tool Steering Wheel Position parameter corresponds to the actual steering wheel position as the steering wheel is turned through its entire range of motion.
- If the parameter does not correspond with the steering wheel position or the reading is erratic
Refer to Circuit/System Testing below.
- If the parameter reading corresponds with the steering wheel position
- If the parameter does not correspond with the steering wheel position or the reading is erratic
- Verify the scan tool Digital HWPS Index Pulse parameter cycles between Low and High as the steering wheel is centered and then turned through its entire range of motion.
- If the parameter does not cycle between Low and High as the steering wheel is turned
Refer to Circuit/System Testing below.
- If the parameter cycles between Low and High as the steering wheel is turned
- If the parameter does not cycle between Low and High as the steering wheel is turned
- All OK
