how do I fix the ABS light on my Honda Accord 10th Generation (2018-2022) that won't turn off

Solution

1. Preparation

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

2. Retrieve Error Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Turn the ignition to the "ON" position without starting the engine.
• Access the ABS system and record any error codes for reference.

3. Inspect Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Clean any dirt or debris from the sensor and mounting area.
• Check the wiring harness for any frays or disconnections.
• Reconnect any loose connections and secure the wiring.

4. Check Brake Fluid and Module

• Inspect the brake fluid reservoir for proper fluid level.
• If low, add OEM-approved brake fluid to the required level.
• Examine the ABS module for any visible damage or leaks.
• Ensure all electrical connections to the ABS module are secure.

5. Test ABS Pump and Relay

• Locate the ABS pump and relay based on the vehicle’s service manual.
• Using a multimeter, test the relay for continuity.
• If faulty, replace the relay with a new one.
• If the pump is suspected to be faulty, consult the service manual for replacement instructions.

6. Reset ABS System

• Reconnect the battery and turn the ignition to "ON."
• Use the OBD-II scanner to clear any stored ABS fault codes.
• Start the vehicle and check if the ABS light remains off.
