Solution

1. Preparation

Required Tools: OBD-II scanner, multimeter, torque wrench, basic hand tools (sockets, wrenches).
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Repair Wiring

Sub-steps:
- Remove the steering column cover to access the wiring harness.
- Visually inspect the wiring for frays, cuts, or corrosion.
- Use a multimeter to check for continuity in the wires associated with the steering angle sensor.
- Repair or replace damaged wiring and connectors as necessary.

3. Replace Steering Angle Sensor (if required)

Sub-steps:
- Remove the steering wheel using a steering wheel puller to access the sensor.
- Unplug the sensor connector and remove any mounting bolts.
- Install the new steering angle sensor, ensuring proper alignment.
- Torque the mounting bolts to the manufacturer's specifications (typically around 15-20 ft-lbs, but check the service manual).
- Reconnect the sensor wiring and reassemble the steering wheel.

4. Calibration

Sub-steps:
- Reconnect the battery and turn the ignition on without starting the engine.
- Use the OBD-II scanner to reset the C0710 code.
- Follow the manufacturer’s procedure for calibrating the steering angle sensor, which may involve turning the steering wheel lock-to-lock several times.
