why does my Honda Accord 9th Generation (2013-2017) traction control light keep coming on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

• Tools Required: Socket set, cleaning brush, isopropyl alcohol.
• Remove the wheel from the affected side.
• Locate the wheel speed sensor on the wheel hub.
• Remove the sensor by unscrewing it from the hub.
• Clean the sensor and its connector with isopropyl alcohol and a cleaning brush.
• Reinstall the wheel speed sensor and secure it with the screws.

3. Check Brake System Components

• Tools Required: Torque wrench, brake cleaner.
• Inspect brake pads and rotors for excessive wear. Replace if necessary.
• Check ABS module connections for corrosion and secure any loose wires.
• Use brake cleaner to remove any debris from the brake components.

4. Inspect Traction Control Module and Wiring

• Tools Required: Multimeter.
• Locate the traction control module under the dashboard.
• Inspect the wiring harness for wear or damage.
• Use a multimeter to test for continuity in the wiring.
• Repair or replace any damaged wires as needed.

5. Verify Battery Voltage

• Tools Required: Multimeter.
• Reconnect the battery terminal.
• Use a multimeter to check the battery voltage; it should be between 12.4V and 12.6V.
• If the voltage is low, consider charging or replacing the battery.
