Solution

1. Preparation

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

2. Inspect and Replace ABS Sensors

Tools Required: Socket set, multimeter, torque wrench
Remove the wheel corresponding to the fault code.
Disconnect the ABS sensor connector and remove the sensor from the wheel hub.
- Sub-step: Use a torque wrench to loosen the sensor mounting bolt to avoid damaging the sensor.
Test the sensor with a multimeter; replace if out of specification.
Install the new sensor in reverse order, ensuring it is properly secured and connected.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir; top off with the manufacturer-recommended brake fluid type.
Ensure there are no leaks from brake lines or the master cylinder.

4. Repair or Replace ABS Module (if necessary)

Tools Required: Socket set, torque wrench
If diagnostics indicate a faulty ABS module, remove it by disconnecting electrical connectors and unscrewing the mounting bolts.
Install the new ABS module in reverse order; torque the bolts to manufacturer specifications.
Reconnect the battery and clear any fault codes using the OBD-II scanner.
