Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, jack, jack stands.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery to avoid electrical shorts.

2. Wheel Speed Sensor Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel corresponding to the suspected faulty wheel speed sensor.
3. Locate the wheel speed sensor on the brake assembly.
4. Inspect the sensor for physical damage or disconnection.
5. Use a multimeter to check the sensor's resistance; it should be within the manufacturer’s specifications (typically 1,000 to 1,500 ohms).
6. If the sensor is faulty, replace it with a new one.

3. ABS Module and Connections Check

Sub-steps:
1. Locate the ABS module, usually near the brake master cylinder.
2. Inspect wiring harnesses for corrosion, loose connectors, or frayed wires.
3. Clean and reconnect any loose or corroded connections.
4. If the ABS module is faulty, replace it according to the manufacturer’s service manual.

4. Brake Fluid Level and Condition

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; it should be between the minimum and maximum marks.
3. If the fluid is low, top it up with the recommended brake fluid (usually DOT 3 or DOT 4).
4. If the fluid is contaminated, perform a brake fluid flush.

5. Traction Control Switch Testing

Sub-steps:
1. Locate the traction control switch, typically near the gear shifter or on the dashboard.
2. Use a multimeter to check for continuity when the switch is pressed.
3. If defective, replace the traction control switch.

6. Tire Condition and Pressure

Sub-steps:
1. Inspect all tires for uneven wear, damage, or low tread depth.
2. Check tire pressure using a tire pressure gauge and inflate to the recommended PSI.
3. If tires are worn out, replace them with new tires.
