how to troubleshoot Honda Accord 10th Generation (2018-2022) traction control light

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and parked securely.
• Disconnect the battery to prevent any electrical issues during inspection.

2. Scan for Error Codes

• Use an OBD-II scanner to retrieve any stored error codes.
• Document the codes for further analysis before clearing them.

3. Inspect and Clean Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Remove any debris or dirt that may be obstructing the sensors.
• If damaged, replace the sensors with new ones.

4. Check Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Check the fluid level; if low, top it off with the recommended brake fluid type (usually DOT 3 or DOT 4).
• Inspect for any visible leaks in the brake lines and fittings.

5. Inspect ABS Module and Wiring

• Locate the ABS module, typically found near the master cylinder.
• Use a multimeter to check for proper voltage and ground connections.
• Inspect the wiring harness for any signs of damage or corrosion; repair or replace as needed.

6. Test Traction Control Switch

• Locate the traction control switch on the dashboard.
• Use a multimeter to test the switch for continuity; replace if faulty.
