Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety during repair.

2. Inspect ABS Wheel Speed Sensors

Remove the wheel corresponding to the sensor in question.
Locate the ABS wheel speed sensor on the hub assembly.
Clean the sensor and the area around it to ensure there are no obstructions.
Reconnect any loose wiring and check for continuity with a multimeter.

3. Check ABS Fuse and Relays

Locate the fuse box and identify the fuse for the ABS system.
Remove the fuse and inspect for continuity using a multimeter.
Replace any blown fuses and inspect relays for proper operation as well.

4. Brake Fluid Level Inspection

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add the manufacturer-recommended brake fluid type.
Look for any signs of leaks around the reservoir and brake lines.

5. Test ABS Pump and Module

Reconnect the battery and turn on the ignition without starting the engine.
Activate the ABS system using a scan tool to run a self-test of the pump and module.
Observe if the pump engages and completes the self-diagnostic routine.
