Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the electrical connector from each sensor.
3. Remove the sensor using a socket set, noting the orientation for reinstallation.
4. Clean the mounting area and install the new sensor, tightening to manufacturer's specifications (typically around 7-10 ft-lbs).
5. Reconnect the electrical connector securely.

3. Check and Replace ABS Module (if necessary)

Sub-steps:
1. Locate the ABS module, typically found near the brake master cylinder.
2. Disconnect the electrical connectors and brake lines leading to the module (be cautious of brake fluid).
3. Remove mounting bolts and take out the ABS module.
4. Install the new ABS module, ensuring correct alignment and torque to specifications (usually 15-20 ft-lbs).
5. Reconnect the brake lines and electrical connectors, ensuring a secure fit.

4. Brake Fluid Inspection and Replacement

Sub-steps:
1. Inspect the brake fluid reservoir for fluid levels and condition (should be clear and at full level).
2. If fluid is contaminated or low, use a brake bleeder kit to purge and replace with new DOT 3 or DOT 4 brake fluid.
3. Bleed the brake lines until clear fluid is observed, ensuring no air bubbles are present.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any fault codes.
Start the vehicle and check that the ABS and traction control lights are no longer illuminated.
