Intermittent Service StabiliTrak, Service Traction Control, or Service All Wheel Drive messages may be displayed on the Driver Information Center of some 2010-2011 Equinox and Terrain models. Any combination of the following DTCs also may be set: C0186, C0196, C0710, U0125, U0126, U1826, and U1827.
DTC U0125 (Lost Communication with Multi-Axis Acceleration Sensor Module) may be set along with DTCs C0186 and/or C0196. Another example may be DTC U0126 (Lost Communication with Steering Wheel Angle Sensor Module) set along with DTC C0710. On all-wheel drive models, DTC U1826 (Lost Communication with Multi-Axis Acceleration Sensor Module on Bus B) or U1827 (Lost Communication with Steering Angle Sensor Module on Bus B) may be set in the Rear Differential Control Module.
If a condition is not identified after following the Service Information diagnostics for the set DTCs, check the J307 splice for circuit 2087 (D-GN wire) for corrosion or partially broken wire strands at the splice crimp. (Fig. 17)
Upon inspection the wire may easily break off when moving the harness. (Fig. 18) Complete the wire repair and clear the DTCs.
