Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connectors and visually inspect for corrosion or damage.
Use a multimeter to check the resistance of the sensors; they should typically be within manufacturer specifications.
Clean the connectors and sensor mounting points if dirty.
Reconnect the sensors securely.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level; if low, top off with the appropriate brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in the brake system that may need to be addressed.

4. Inspect ABS Module

Locate the ABS module, typically near the master cylinder.
Check for any damaged wires or connectors.
If necessary, use a multimeter to test for proper voltage and ground at the ABS module connectors.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it is found to be faulty.

6. Verify Tire Pressure

Use a tire pressure gauge to check the pressure on all tires.
Inflate or deflate tires to the manufacturer-recommended PSI found in the owner’s manual or on the driver’s side door jamb.
