Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts while working on the ABS system.

2. Inspect and Replace ABS Wheel Speed Sensors

Remove the wheel corresponding to the ABS sensor that was flagged in the diagnostic scan.
Locate the ABS wheel speed sensor and disconnect the electrical connector.
Unscrew the sensor from its mounting position (use appropriate socket).
Clean the mounting area to ensure a good seal for the new sensor.
Install the new ABS wheel speed sensor and reconnect the electrical connector.
Reinstall the wheel and torque lug nuts to vehicle specifications.

3. Check and Replace Brake Fluid

Inspect the brake fluid reservoir. If the fluid is low, top it up with the manufacturer-recommended brake fluid (typically DOT 4).
If the fluid is contaminated (dark or particles present), perform a brake fluid flush using the recommended fluid.
Bleed the brake lines to remove any air from the system afterward.

4. Inspect and Replace ABS Module (if necessary)

If diagnostics indicate a faulty ABS module, remove the module following the manufacturer’s service manual.
Disconnect electrical connectors and unscrew the module from its mounting position.
Install the new ABS module, reconnect electrical connectors, and torque to manufacturer specifications.
Reconnect the battery.
