C0710 on GMC by model: symptoms, diagnosis and fix
The Hummer EV SUV's adaptive air suspension system, which offers up to 16 inches of ground clearance in Extract Mode, can develop calibration errors that prevent the system from reaching full height. The height sensors, air compressor, and air springs must all function in concert. Software bugs can cause the system to display incorrect ride height or refuse to enter Extract Mode. The compressor can also overheat from repeated height adjustment cycles, entering a cooldown period that locks out suspension adjustments.
Common Symptoms
- Extract Mode not reaching full height
- Suspension malfunction warning message
- Vehicle sitting unevenly
- Ride height adjustments not responding
- Compressor cooldown message after multiple height changes
How to Fix
GM has released software updates that improve air suspension calibration accuracy. Visit the dealer for recalibration using the GDS2 diagnostic tool. If the compressor overheats, allow it to cool for 30 minutes before attempting further adjustments. For persistent Extract Mode failures, the height sensors may need recalibration or replacement.

Frequently asked questions
What does C0710 mean on a GMC?
C0710 stands for "Steering Position Sensor." C0710 is a chassis code indicating a fault with the steering position (steering angle) sensor, which tells stability control and related systems how far and how fast you are turning the wheel. The control module compares this signal to other inputs, and when the steering sensor reading is missing, out of range, or implausible, it sets this code. You may lose stability control, traction control, or electronic steering assist, with corresponding warning lights. It points to the steering angle sensor or its circuit rather than a mechanical steering part. On GMC it is documented across 1 model: Hummer EV SUV.
What are the most common causes of C0710?
The most common causes of C0710 are: Faulty steering angle/position sensor, Steering angle sensor needs calibration after service, Damaged clockspring affecting the sensor circuit, Wiring or connector fault at the sensor, Loss of power or ground to the sensor, Communication fault between the sensor and stability module, Worn steering column components affecting sensor reading. The specific cause varies by vehicle.
How much does it cost to fix C0710 on a GMC?
Repair costs vary widely with the root cause and GMC model; each issue on this page carries its own estimate where one is published.
