Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is on a flat surface and the ignition is off before beginning work.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connectors and inspect wiring for damage.
Use a multimeter to check the resistance of each sensor; it should typically be within manufacturer specifications (refer to the service manual).
Clean any debris from the sensors if necessary and reconnect.

3. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top it up with the recommended brake fluid type.
Check for leaks in brake lines, hoses, and connections.
If leaks are detected, repair or replace affected components.

4. Tire Inspection

Visually inspect all tires for uneven wear or damage.
Measure tread depth; replace tires if the tread is below the manufacturer’s recommended minimum.
Ensure all tires are inflated to the correct PSI as specified in the owner’s manual.

5. ABS Module Inspection

Locate the ABS module, usually found near the master cylinder.
Check for any visible damage or loose connections.
If error codes indicate a fault, refer to the service manual for specific diagnostic procedures or replacement steps.
