Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensors by unscrewing the retaining bolts.
Clean any dirt or debris around the sensor area using brake cleaner.
Check the sensor terminals for corrosion or damage.
Use a multimeter to check the resistance of the sensor (should typically be within manufacturer specifications).
Reinstall the sensors and torque the bolts to the manufacturer's specifications.

3. Check ABS Module and Wiring

Visually inspect the ABS module for any signs of damage or corrosion.
Follow the wiring harness to ensure there are no cuts or frays.
Use a multimeter to test the continuity of the wiring from the sensors to the ABS module.
Repair or replace any damaged wiring as necessary.

4. Replace Faulty Components

If any wheel speed sensors are found to be faulty, replace them with new parts.
If the ABS module is malfunctioning, replace it with a new or remanufactured ABS module.
Ensure that all new parts are installed according to the manufacturer's specifications.

5. Reset the ABS Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and verify that the ABS light is no longer illuminated.
