why is my Honda Accord Eleventh Generation (2023-present) ABS light on and traction control disabled

Solution

1. Preparation

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

2. Retrieve Fault Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Turn the ignition to the "ON" position without starting the engine.
• Follow the scanner prompts to retrieve and record any ABS-related fault codes.

3. Inspect and Replace ABS Wheel Speed Sensors

• Locate the ABS wheel speed sensors at each wheel hub.
• Disconnect the electrical connector from each sensor.
• Remove the sensor using the appropriate socket.
• Clean the sensor mounting area and the sensor itself.
• Install the new sensor and reconnect the electrical connector.
• Repeat for all affected sensors as indicated by fault codes.

4. Check and Replace Fuse

• Identify the location of the ABS fuse in the fuse box (refer to the owner's manual).
• Remove the fuse and inspect it visually for any damage.
• If blown, replace it with a fuse of the same rating.

5. Inspect Brake Fluid

• Check the brake fluid level in the master cylinder reservoir.
• If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified).
• Inspect for any signs of leaks in the brake lines or around the master cylinder.

6. Reconnect Battery and Clear Codes

• Reconnect the battery terminals, ensuring they are tight and secure.
• Use the OBD-II scanner to clear any fault codes stored in the system.
• Turn the ignition back to the "ON" position and check if the ABS and traction control lights are off.
