Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level and condition; if dirty or low, proceed to replace it.
Use a turkey baster to remove old fluid from the reservoir.
Refill the reservoir with the manufacturer-recommended power steering fluid.
Reconnect the battery terminal.

3. Check and Replace EPS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the EPS system using the fuse diagram in the owner’s manual.
Remove the fuse and inspect it for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage.

4. Inspect and Replace EPS Motor or Sensor

If error codes indicate a malfunctioning EPS motor or sensor, proceed with removal:
- Remove the steering wheel by unfastening the airbag module and disconnecting the wiring harness.
- Unscrew and detach the EPS motor from the steering column.
- Install the new EPS motor or sensor, ensuring all connections are secure and aligned.
- Reassemble the steering wheel and airbag module, ensuring all components are correctly fitted.

5. Reset EPS Light

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any EPS-related fault codes.
Turn the steering wheel lock-to-lock to recalibrate the EPS system.
