Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Sub-steps:
1. Raise the vehicle using jack stands and remove the wheels to access the wheel speed sensors.
2. Disconnect the electrical connector from each wheel speed sensor.
3. Use a multimeter to test the voltage output of each sensor; if any sensor shows inconsistent readings, replace it.
4. Install new sensors, reconnect the electrical connectors, and reattach the wheels.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4), funnel.
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, fill it to the recommended level with appropriate brake fluid.
3. Inspect for any visible leaks in brake lines and connections.

4. Test and Replace ABS Module (if necessary)

Tools Required: Diagnostic tool capable of ABS testing.
Sub-steps:
1. Connect the diagnostic tool to the OBD-II port and check for ABS module errors.
2. If errors are present and the module is confirmed faulty, remove it by disconnecting electrical connectors and unbolting from the mounting bracket.
3. Install the new ABS module and reconnect all connectors, ensuring a proper fit.
