Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, torque wrench, replacement ABS sensors (if needed), brake fluid.
Park the vehicle on a level surface and engage the parking brake.

2. Addressing Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any ABS-related fault codes.
Clear the codes and test drive the vehicle to see if the ABS light returns.

3. Inspecting Wheel Speed Sensors

Raise the vehicle and remove the front and rear wheels for access.
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the sensor connectors and inspect the sensors for dirt or damage.
Clean the sensors with a soft cloth and reconnect them.
If damaged, replace the sensors:
- Remove the sensor mounting bolts.
- Install the new sensor and torque the bolts to manufacturer specifications (usually around 7-10 ft-lbs).

4. Check ABS Module and Wiring

Inspect the wiring harness and connectors for any signs of wear, corrosion, or disconnection.
Use a multimeter to check for continuity in the ABS module wiring.
If the wiring is damaged, repair or replace as necessary.

5. Final Steps

Refill brake fluid if necessary, using manufacturer-recommended fluid.
Reassemble any components removed during inspection.
Lower the vehicle and perform a final check on all connections.
