why does my Honda Accord ABS light come on and traction control disabled

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and securely lifted with jack stands.
• Disconnect the negative battery terminal to avoid any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

• Sub-steps:
  1. Locate the ABS wheel speed sensors at each wheel hub assembly.
  2. Disconnect the electrical connector from the sensor.
  3. Remove the mounting bolt holding the sensor in place.
  4. Carefully extract the sensor from the hub.
  5. Install the new ABS sensor by reversing the removal steps, ensuring it is properly seated and connections are secure.

3. Check and Replace ABS Fuse/Relay

• Sub-steps:
  1. Locate the fuse box and identify the ABS fuse using the diagram on the lid.
  2. Remove the fuse and check for continuity with a multimeter; replace if blown.
  3. Locate the ABS relay and perform the same continuity check.
  4. Replace the relay if defective.

4. Inspect Brake Fluid Level

• Sub-steps:
  1. Check the brake fluid reservoir for proper fluid level; refill with the manufacturer's recommended brake fluid if low.
  2. Inspect the fluid for contamination; if dirty, flush the brake system and replace with new fluid.

5. Reconnect Battery and Reset ABS System

• Sub-steps:
  1. Reconnect the negative battery terminal.
  2. Use an OBD-II scanner to clear any stored error codes.
  3. Start the vehicle and check if the ABS and traction control lights remain off.
