Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse for the power steering system and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage rating.

3. Clean and Inspect Connectors

Tools Required: Electrical contact cleaner, brush, and cloth.
Disconnect the electrical connectors from the power steering unit.
Clean any corrosion or dirt from the connectors using electrical contact cleaner.
Reconnect the connectors securely.

4. Test the Steering Angle Sensor

Tools Required: Multimeter.
Access the steering angle sensor, typically mounted on the steering column.
Using a multimeter, check the resistance and voltage output of the sensor according to the manufacturer’s specifications.
Replace the sensor if readings are outside of specified ranges.

5. Check Power Steering Fluid

Tools Required: Fluid funnel and container for draining if necessary.
Locate the power steering fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended power steering fluid.
If the fluid appears contaminated, drain and replace with fresh fluid.

6. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored C-codes.
Start the vehicle to check if the warning light reappears.
