Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Repair Wiring

Tools Required: Wire brush, electrical tape, multimeter, soldering iron.
Visually inspect all wiring connected to the ABS module for any signs of wear or damage.
Use a multimeter to test for continuity in the wires leading to the ABS module. Repair any damaged wiring by soldering or replacing sections as needed.
Secure any loose connections with electrical tape or heat shrink tubing.

3. Replace Wheel Speed Sensors (if necessary)

Tools Required: Socket set, torque wrench, impact driver.
Locate each wheel speed sensor by removing the corresponding wheel.
Detach the sensor from its mount and disconnect the electrical connector.
Install the new wheel speed sensor by reversing the removal process, ensuring all connections are secure.
Torque the sensor bolts to manufacturer specifications (usually around 10-15 ft-lbs).

4. Reconnect ABS Module

Reconnect the ABS module connectors ensuring a secure fit.
Reconnect the vehicle's battery and turn on the ignition.

5. Clear Codes and Test Drive

Use an OBD-II scanner to clear the U0415 code and any other related codes.
Test drive the vehicle to ensure the ABS and traction control systems are functioning properly and that the warning lights do not return.
