Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with the same amperage rating.

3. Check and Top Off Brake Fluid

Locate the master cylinder reservoir, usually found near the back of the engine bay.
Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
Reconnect the negative battery terminal.

4. Inspect ABS Wheel Speed Sensors

Lift the vehicle securely using jack stands.
Locate the ABS wheel speed sensors near each wheel hub.
Check for physical damage or disconnection; clean any dirt or debris from the sensors.
If damaged, replace the sensor with an OEM part.

5. Test ABS Module

Reconnect the battery and use a multimeter to test the ABS module's power and ground connections.
Follow wiring diagrams specific to the model for accurate testing.
If the module is faulty, replace it with a new or refurbished unit.
