Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Fuse

Locate the Fuse Box: Refer to the owner's manual to find the location of the EPS fuse.
Remove Fuse: Use a fuse puller to remove the EPS fuse.
Inspect Fuse: Check if the fuse is blown (a broken wire or discolored).
Replace Fuse: If blown, replace it with an identical-rated fuse.

3. Repair Wiring and Connectors

Inspect Wiring: Carefully examine the EPS wiring harness for any signs of damage or wear.
Repair or Replace: Repair any damaged wires with electrical tape or connectors as necessary, or replace the entire harness if severely damaged.

4. Test and Replace EPS Motor (if necessary)

Test Motor: Use a multimeter to check if the EPS motor is receiving power.
Replace EPS Motor: If the motor is faulty, disconnect the wiring harness and mounting bolts, then remove and replace the EPS motor with a new unit.

5. Reconnect Battery and Calibration

Reconnect Battery: Once repairs are complete, reconnect the battery.
Calibrate Sensor: Use a diagnostic tool to calibrate the steering angle sensor as per manufacturer specifications.
