Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on the EPS system.

Tools Required:

OBD-II scanner
Multimeter
Torque wrench
Socket set
Screwdrivers

2. Inspect and Replace EPS Fuse

Locate the EPS fuse in the fuse box (refer to the owner's manual for exact location).
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir (check the owner's manual for location).
Remove the cap and check the fluid level; if low, add the recommended power steering fluid.
If the fluid appears dirty or contaminated, drain the old fluid and replace it with fresh fluid.

4. Inspect EPS Motor and Wiring

Visually inspect the EPS motor and wiring harness for any signs of wear, fraying, or corrosion.
If any damage is found, replace the affected wiring or the entire EPS motor as necessary.

5. Test EPS Control Module

Reconnect the battery and use a multimeter to check the voltage at the EPS control module connector.
Ensure that the voltage and ground signals are present as specified in the service manual.
If the control module is faulty, replace it according to manufacturer instructions.
