how to fix the traction control light that stays on in my Honda Accord 10th Generation (2018-2022)

Solution

1. Preparation

• Gather necessary tools and ensure the vehicle is on a flat surface.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Record any trouble codes that appear and address them accordingly based on their descriptions.

3. Inspect Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Remove any debris or dirt from the sensors.
• Check the wiring harness connected to each sensor for loose connections or damage.
• Replace any damaged sensors as necessary.

4. Check Brake Fluid

• Open the hood and locate the brake fluid reservoir.
• Inspect the brake fluid level; if low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
• If the fluid is contaminated, flush the brake system and replace the fluid.

5. Test Traction Control Switch

• Locate the traction control switch, usually near the gear shifter or on the dashboard.
• Press the switch to toggle the traction control system on and off.
• If the switch is malfunctioning, replace it with a new one.

6. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear any trouble codes after repairs.
