Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent electrical shock or short circuits.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Brake cleaner

2. Inspect ABS Wheel Speed Sensors

Remove the wheel corresponding to the ABS light issue.
Locate the ABS wheel speed sensor on the hub assembly.
Clean the sensor and surrounding area with brake cleaner.
Check the sensor's wiring for any damage or corrosion.
Reattach the sensor and wheel, ensuring all bolts are tightened to the manufacturer's torque specifications.

3. Check ABS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter. Replace the fuse if it is blown.

4. Test ABS Pump and Module

Reconnect the battery.
Use the OBD-II scanner to clear any stored ABS error codes.
Perform a functionality test of the ABS pump by activating the system through the scanner.
If the pump does not activate, further diagnostics on the module and pump wiring may be required.

5. Final Assembly and Check

Reassemble any components removed during the process.
Ensure that all connections are secure and there are no visible leaks in the brake system.
Tighten all bolts to the manufacturer's specifications.
