Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect Brake Fluid and Lines

Tools Required: Brake fluid, brake line wrench.
Sub-steps:
1. Remove the brake fluid reservoir cap and check the fluid level; top off if low.
2. Inspect brake lines for signs of leaks or corrosion, particularly around the ABS module.
3. If a leak is found, replace damaged brake lines or fittings as necessary.

3. Check ABS Sensors

Tools Required: Multimeter, socket set.
Sub-steps:
1. Locate the wheel speed sensors on each wheel and visually inspect for dirt or damage.
2. Disconnect the sensor connectors and test the resistance using a multimeter; refer to specifications for acceptable ranges.
3. If a sensor is faulty, remove the mounting bolt and replace the sensor.

4. Inspect ABS Module

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Locate the ABS module and visually inspect it for any signs of damage or leaks.
2. If necessary, remove the module by disconnecting the wiring harness and any mounting bolts.
3. Install the new ABS module and secure it with the appropriate torque specifications.

5. Clear Error Codes and Test

Tools Required: OBD-II scanner.
Sub-steps:
1. Reconnect the battery and start the vehicle.
2. Use the OBD-II scanner to clear any stored error codes in the ABS system.
3. Test drive the vehicle to ensure the ABS light remains off and that brakes function correctly.
