DTC C0710

DTC C0710 Step 1 - 7:

Circuit Description
Under normal driving conditions, the EBCM monitors the steering angle sensor inputs to see if the steering wheel is moving. If the steering wheel is not moving for a set period of time, the EBCM assumes the vehicle is going in a straight line. At this point, the EBCM looks at the steering angle sensor inputs and considers the degree angle to be zero. This is called the offset value.

Steer angle centering is the process by which the EBCM calibrates the steering sensor output so that the output reads zero when the steering wheel is centered.

Conditions for Running the DTC
- The ignition is ON.
- The vehicle speed is greater than 40 km/h (25 mph).

Conditions for Setting the DTC
A malfunction is detected if one or more of the following conditions exist:
- The steering angle sensor detects an internal malfunction and sends a CAN message to the EBCM.
- If the offset value is higher than 15 degrees, a malfunction is detected. Malfunction time depends on driving distance, vehicle speed and the amount of malfunctioning steering angle signal.
- Rapid changes of the steering angle sensor signal cannot occur under normal driving conditions. If the signal change is higher than 2000 degrees per second or steering angle acceleration is higher than 37500 degrees per second squared, a malfunction is detected.
- A reference steering angle signal based on a vehicle model is used to check the actual steering angle. If the measured steering angle varies from the reference steering angle by more than a predetermined value, a malfunction is detected.

Action Taken When the DTC Sets
If equipped, the following actions occur:
- The EBCM disables the TCSNSES and for the duration of the ignition cycle.
- A malfunction DTC will set.
- The Stability Off indicator turns on.

Conditions for Clearing the DTC
- The condition for the DTC is no longer present.
- A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
- Using a scan tool.
- The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
