Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect ABS Fuse

Locate the fuse box and identify the fuse for the ABS system.
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for continuity. Replace if blown.

3. Check Wheel Speed Sensors

Raise the vehicle and securely support it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connectors and visually inspect for dirt, corrosion, or damage.
Use a multimeter to check the resistance of each sensor; replace any that are out of specification.

4. Inspect Wiring Harness

Examine the wiring harness connected to the ABS module and wheel speed sensors.
Look for any signs of wear, fraying, or disconnection.
Repair or replace damaged wiring as necessary.

5. Test ABS Module and Pump

Reconnect the battery terminal.
Turn the ignition to the ON position without starting the engine.
Listen for the ABS pump activation sound; if there’s no sound, further diagnostics may be needed.
If codes indicate a module issue, consider replacement of the ABS control module.

6. Refill Brake Fluid

Check the brake fluid reservoir for the correct level.
If low, top up with the recommended brake fluid type (usually DOT 3 or DOT 4).
Bleed the brake system if air is present.
