what are the common symptoms of electric power steering failure in Toyota Camry XV70 (2018-2024)?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a flat surface, engage the parking brake, and disconnect the negative battery terminal for safety.

2. Inspect and Replace EPS Fuse

• Locate the fuse box (usually under the dashboard or in the engine compartment).
• Remove the EPS fuse using a fuse puller or needle-nose pliers.
• Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Check and Repair Wiring

• Inspect the wiring harness connected to the EPS motor and ECU for any signs of wear, fraying, or damage.
• If damage is found, repair the wiring with solder and heat-shrink tubing or replace the harness if necessary.

4. Test and Replace EPS Motor (if necessary)

• If the motor is not functioning correctly, remove it from the steering column.
• Disconnect the electrical connector and unscrew the mounting bolts.
• Replace the EPS motor with a new unit, ensuring it is correctly aligned and secured.

5. Reassemble and Reconnect

• Reconnect all electrical connectors and ensure they are secure.
• Reinstall the fuse and reconnect the negative battery terminal.
• Start the vehicle and check for any warning lights on the dashboard.
