Solution

1. Preparation

Gather necessary tools and materials.
Ensure vehicle is parked on a level surface and securely raise the vehicle if needed.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-steps:
- Locate the ABS wheel speed sensors at each wheel hub.
- Disconnect the electrical connector from the sensor.
- Remove the sensor using a socket or wrench (typically 10mm).
- Inspect the old sensor for damage or debris; clean the mounting hole.
- Install the new sensor, ensuring it is seated properly and secure it to the hub.
- Reconnect the electrical connector.

3. Check and Replace ABS Module (if necessary)

Sub-steps:
- If error codes indicate a fault with the ABS control module, locate the module typically found near the master cylinder.
- Disconnect the electrical connectors and vacuum lines attached to the module.
- Remove the mounting bolts securing the module and carefully detach it.
- Install the new ABS module, tightening bolts to manufacturer specifications (consult service manual for torque values).
- Reconnect all electrical connectors and vacuum lines.

4. Reconnect Battery and Reset System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes from the ABS system.
Check that all systems are functioning correctly.
