Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies (e.g., brake cleaner), safety glasses.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Clean ABS Wheel Speed Sensors

Sub-steps:
- Locate the ABS wheel speed sensors at each wheel hub.
- Remove the sensor mounting bolts using a socket set.
- Clean any debris or dirt from the sensor using brake cleaner.
- Inspect the sensor for cracks or damage, and replace if necessary.
- Reinstall the sensors and torque the bolts to the manufacturer’s specifications.

3. Check and Replace ABS Fuse

Sub-steps:
- Locate the fuse box, typically found under the dashboard or in the engine compartment.
- Remove the ABS fuse and inspect it for continuity using a multimeter.
- If the fuse is blown, replace it with a new fuse of the same amperage.
- Recheck the ABS light after replacing the fuse.

4. Test ABS Module

Sub-steps:
- Reconnect the battery terminal and use the OBD-II scanner to check for active codes.
- If codes are present indicating a malfunctioning ABS module, proceed with module replacement following manufacturer guidelines.
- Disconnect the module, replace it, and ensure all connections are secure.
