Solution

1. Preparation

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

2. Check ABS Fuse

Locate the fuse box (refer to the owner’s manual for location).
Remove the ABS fuse using a fuse puller.
Inspect the fuse visually or check for continuity with a multimeter.
Replace the fuse if it is blown.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Inspect the sensors for physical damage or dirt accumulation.
Clean the sensors with an appropriate cleaner if dirty, and reconnect any loose connections.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level; it should be between the minimum and maximum marks.
If low, refill with the recommended brake fluid type as specified in the owner’s manual.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the ABS module for any signs of wear or damage.
Disconnect the ABS module connector and inspect for corrosion or bent pins.
Reconnect securely after inspection.

6. Test ABS Module

Reconnect the negative battery terminal.
Use a diagnostic tool to access the ABS module.
Follow the tool instructions to activate the ABS system and check for proper operation.
Clear any fault codes and test drive the vehicle to ensure the ABS light does not reappear.
