Diagnostic Steps

1
Scan the ABS system using an OBD-II scanner to retrieve any error codes.
2
Inspect the wheel speed sensors for damage or disconnection.
3
Check the ABS fuse for continuity and proper function.
4
Verify brake fluid level and check for leaks in the brake system.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read the ABS codes and note them for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Check for physical damage or dirt accumulation.
Clean the sensors with an appropriate brake cleaner if necessary.
Ensure all electrical connectors are secure and free from corrosion.

4. Check ABS Fuse

Locate the fuse box and identify the ABS fuse based on the owner's manual.
Remove the fuse and inspect it for continuity using a multimeter.
Replace with a new fuse if blown, ensuring it matches the specified amperage.

5. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any visible leaks in brake lines, calipers, or hoses.

6. Repair or Replace Faulty Components

If error codes indicate a specific faulty wheel speed sensor, replace it with a new one.
If the ABS module is suspected to be faulty, consult the manufacturer for replacement procedures.
