Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the ABS fuse using the diagram on the fuse box cover.
Use a multimeter to check the fuse for continuity. Replace with the same amperage if found blown.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Check for any visible leaks in brake lines and components.

4. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Locate the wheel speed sensors on each wheel hub assembly.
Clean the sensors with a soft cloth and inspect the wiring for signs of wear or damage.
If damaged, carefully remove the old sensor and install a new one, ensuring proper torque specifications are followed.

5. Test ABS Pump and Module

Reconnect the battery terminal.
Use an ABS scan tool to perform a functional test of the ABS pump and module.
If the pump fails to activate, further diagnostics may be needed, including checking wiring and connections.
