Solution

1. Preparation

• Gather necessary tools and components.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to prevent electrical short circuits.

2. Inspect Wheel Speed Sensors

• Tools Required: Socket set, multimeter
• Remove the wheel for access to the wheel speed sensor.
• Check the sensor connector for corrosion or damage.
• Measure the resistance of the wheel speed sensor using a multimeter; it should be within manufacturer specifications (typically between 1000-2000 ohms).
• If the sensor is faulty, replace it with a new one.

3. Inspect ABS Module

• Reconnect the battery terminal and turn the ignition to the ON position without starting the engine.
• Use a scan tool to check for any additional codes related to the ABS module.
• If the ABS module is not functioning correctly, follow the manufacturer’s procedure to replace or reprogram the module.

4. Check Wiring and Connectors

• Inspect the wiring harness leading to the wheel speed sensors for any signs of wear, fraying, or short-circuits.
• Ensure that all connectors are clean and securely fastened.

5. Verify Brake Fluid Level

• Open the hood and check the brake fluid reservoir.
• If the fluid is low, top it off with the correct type of brake fluid (usually DOT 3 or DOT 4 as specified in the owner's manual).
