Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery to ensure safety.
Tools required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.

2. Inspect ABS Fuse

Locate the fuse box (consult owner’s manual for exact location).
Remove the ABS fuse using a fuse puller.
Inspect the fuse for continuity with a multimeter. Replace if blown.

3. Check ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Locate the wheel speed sensors at each wheel.
Inspect wiring and connectors for damage or corrosion.
Clean any dirt or debris from the sensor and mounting area.
Reconnect any loose connections.

4. Examine ABS Control Module Wiring

Follow the wiring harness from the ABS module to the connectors.
Look for frayed wires, corrosion, or disconnections.
Repair or replace damaged wiring as necessary.

5. Inspect Brake Fluid and Lines

Check the brake fluid reservoir for proper fluid level.
Inspect brake lines for leaks or damage.
If fluid is low, fill it with the recommended brake fluid type (usually DOT 3 or DOT 4).
Replace any damaged brake lines.

6. Test ABS Pump Operation

Reconnect the battery.
Start the vehicle and activate the ABS system by driving at low speed and applying the brakes.
Listen for the ABS pump operation; it should activate briefly.
If the pump does not activate, the ABS module may require replacement.
