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 battery terminal for safety.

2. Inspect and Replace ABS Fuse

Locate the fuse box in the engine compartment.
Remove the cover and find the ABS fuse using the fuse diagram.
Inspect the fuse; if blown, replace it with a fuse of the same amperage.
Reconnect the fuse box cover and the negative battery terminal.

3. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it's below the minimum mark, top it off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Inspect the fluid for contamination; if dirty, consider a brake fluid flush.

4. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS wheel speed sensor.
Clean any dirt or debris from the sensor area and check the sensor for physical damage.
If damaged, remove the sensor and replace it with a new one.

5. Test ABS Pump Operation

Reconnect the negative battery terminal.
Use a scan tool to activate the ABS pump; listen for operation sounds.
If the pump does not activate or you hear unusual noises, consider replacing the ABS module.
