Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the ABS fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check Brake Fluid Level

Tools Required: Clean rag
Remove the master cylinder cap and inspect the brake fluid level.
If low, top up with the manufacturer's specified brake fluid (DOT 3 or DOT 4, as recommended).
Reinstall the cap securely.

4. Inspect ABS Wheel Speed Sensors

Tools Required: Socket set, torque wrench
Raise the vehicle safely using jack stands.
Locate each wheel speed sensor and check for dirt or damage.
Clean any debris from the sensor's surface with a clean rag.
If damaged, remove the sensor by unscrewing it and replace it with a new one, tightening to manufacturer specifications.

5. Examine Wiring and Connectors

Tools Required: Multimeter
Inspect the wiring and connectors for any signs of wear, corrosion, or disconnection.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wiring or connectors as necessary.

6. Test ABS Pump and Module

Tools Required: Multimeter
Reconnect the battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Use the multimeter to test voltage at the ABS pump and module connections.
If the pump is not receiving power, further inspection of the wiring harness is necessary.
