Stability activation C0710

Diagnose and fix Stability activation C0710

GM has issued multiple service bulletins to fix issues with unwanted stability activation and service stability messages. This particular service bulletin #PIT4322H relates only to unwanted stability activation but the links listed below refer to other GM stability control issues. Needless to say, GM has problems with its stability control.

GM service bulletin #PIT4322H

This bulletin addresses unwanted stability activation and trouble cod C0710 on the vehicles listed below. Trouble code C01710 relates to the steering position signal. However, if the vehicle has been lifted or lowered, had different size wheels installed or a different steering gear installed, these modifications can cause unwanted stability activation. To prevent the unwanted stability activation, remove the modifications.

If the vehicle has NOT been modified, continue with these checks

Check to ensure all tires are the same size and tire pressure. Next check the operation of the steering position sensor. Connect a scan tool and check that digital signals for steering position Phase A and Phase B move up and down between high and low as you rotate the wheel.

In addition to the high low sweep, steering position signal A should be 2.5-volts when he steering wheel is in the straight ahead position. As you rotate the wheel, the voltage should range between 0.8 and 3.8-volts. The Yaw rate sensor should read 2.5-volts when the vehicle is standing still. Jostling the vehicle will change the voltage. Lateral acceleration value should be 0-ft/lbs.

If the steering position readings are off, perform a steering position sensor calibration or replace the steering position sensor. In most cases, the steering position sensor is at fault for a C0710 trouble code
