Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, brake fluid, and cleaning supplies.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Disconnect the battery negative terminal to prevent any electrical issues while working.

2. ABS Fuse Inspection

Locate the ABS fuse in the fuse box (refer to the owner’s manual for exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity using a multimeter; replace if blown.

3. Brake Fluid Level Check

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 recommended brake fluid (DOT 4).
Inspect for any visible leaks around the brake lines and connections.

4. Wheel Speed Sensor Examination

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Inspect the sensors and their wiring for damage, dirt, or disconnection.
Clean the sensors with brake cleaner if they are dirty.

5. ABS Control Module Testing

Reconnect the battery terminal and use the OBD-II scanner to access ABS system data.
Check for fault codes; if any are present, address the specific issue indicated.
If no codes are present, test the control module for proper functionality using diagnostic equipment.

6. Brake System Inspection

Inspect the brake pads and rotors for wear and replace if they are below manufacturer specifications.
Ensure all brake components are functioning properly and are tightened to specified torque values.
