Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts during repair.

2. Inspect and Replace ABS Fuse/Relay

Locate the fuse box (consult the owner’s manual for the exact location).
Identify the ABS fuse and relay using the fuse diagram.
Remove the fuse and relay using fuse puller or needle-nose pliers.
Inspect for any signs of damage; replace if necessary with OEM parts.

3. Clean or Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel.
Clean the sensor area with brake cleaner and a soft cloth to remove debris.
If damaged, remove the sensor by unscrewing the mounting bolt and disconnecting the wiring harness.
Install the new sensor and reconnect the wiring harness, ensuring a secure fit.

4. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Remove the cap and check fluid level; refill with the manufacturer's recommended brake fluid if low.
If the fluid is dirty or contaminated, perform a brake fluid flush.

5. Test ABS Module and Pump

Reconnect the battery.
Use an ABS diagnostic scanner to check the operation of the ABS module.
Activate the ABS pump and ensure it engages properly.
If the module is faulty, follow the manufacturer's instructions for removal and replacement.
