C0760 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 C0760 mean on a GMC?
C0760 stands for "ABS System Disabled." This chassis code indicates that the anti-lock braking system (ABS) has been disabled or is being commanded off due to a detected fault. When the ABS control module finds a problem it cannot tolerate, it shuts down ABS function and usually illuminates the ABS warning light, often disabling related features like traction or stability control as well. Importantly, normal hydraulic braking still works, but the anti-lock and electronic assistance features are turned off. This code is typically a result of another underlying fault, so the system should be scanned for accompanying codes that point to the root cause. On GMC it is documented across 1 model: Hummer EV SUV.
What are the most common causes of C0760?
The most common causes of C0760 are: Faulty wheel speed sensor or damaged sensor wiring, Low system voltage or charging problem, Faulty ABS control module, Blown fuse or power supply fault to the ABS system, Poor ground or connector corrosion in the ABS circuit, Another active ABS fault triggering system shutdown, Communication (network) fault with the ABS module. The specific cause varies by vehicle.
