Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake cleaner, torque wrench.
Disconnect the negative battery cable to prevent electrical shock and damage.

2. Scan for Codes

Use the OBD-II scanner to retrieve any stored trouble codes related to the ABS system.
Note down the codes for reference during repairs.

3. Inspect Fuses and Relays

Locate the fuse box and check the ABS fuses and relays.
Replace any blown fuses and faulty relays as needed.

4. Wheel Speed Sensor Inspection

Raise the vehicle and remove the wheels to access the wheel speed sensors.
Clean any dirt or debris from the sensors and their connectors.
Check the wiring for any signs of damage or corrosion.

5. Test Wheel Speed Sensors

Using a multimeter, test the resistance of each wheel speed sensor.
Compare readings with manufacturer specifications (usually between 1,000-2,000 ohms).
Replace any sensors that are out of specification.

6. Inspect ABS Module

Visually inspect the ABS module for any signs of damage or corrosion.
If necessary, replace the ABS module following manufacturer specifications for torque values during reinstallation.

7. Reassemble and Reconnect

Reinstall any components removed for access, including wheels.
Reconnect the negative battery cable.
