Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, brake cleaner.
Gather necessary parts based on diagnostic findings (e.g., ABS sensor, wire harness).
Disconnect the battery to ensure safety before working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly and wheel speed sensor.
3. Carefully detach the wheel speed sensor connector.
4. Inspect the sensor for dirt or debris and clean with brake cleaner and a soft brush.
5. Reconnect the sensor and reinstall the wheel.

3. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box (refer to owner’s manual for specific location).
2. Identify the ABS fuse and use a multimeter to check for continuity.
3. If the fuse is blown, replace it with a new fuse of the same amperage.
4. Reconnect the battery and check if the ABS light is still illuminated.

4. Inspect ABS Module and Wiring

Sub-steps:
1. Locate the ABS module, usually near the master cylinder.
2. Inspect the wiring harness for frayed wires or corrosion; repair or replace as necessary.
3. Ensure all connectors are secure and free of rust.
4. If the module is suspected to be faulty, replace it according to manufacturer specifications.
