Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, screwdrivers, safety gloves, and safety glasses.
Disconnect the negative battery terminal to prevent electrical shock and ensure safety during repairs.

2. Inspect and Clean ABS Sensors

Locate the ABS wheel speed sensors at each wheel.
Remove the dirt and debris around the sensors using a soft brush and a clean cloth.
Check the sensor mounting bolts for corrosion; clean or replace if necessary.

3. Replace Faulty ABS Wheel Speed Sensor

If the resistance test indicates a faulty sensor, proceed with replacement:
- Tools Required: Socket set.
- Remove the wheel corresponding to the faulty sensor.
- Unscrew the sensor from its mount and disconnect the electrical connector.
- Install the new sensor and reconnect the electrical connector.
- Torque the sensor to manufacturer specifications (typically 7-11 lb-ft).

4. Repair or Replace Damaged Wiring

Inspect the wiring harness for any frayed, damaged, or corroded wires.
If damage is found, repair the wiring using appropriate connectors or replace the entire harness if necessary.

5. Reset the ABS System

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear the trouble codes from the ABS system.
Perform a brake system check to ensure proper operation.
