Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Remove the sensor using a socket set (usually a 10mm socket).
Clean the sensor and its mounting area with brake cleaner.
Reinstall the sensor and connector, ensuring a secure fit.

3. Check ABS Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Use a fuse puller to remove the ABS fuse.
Inspect the fuse for continuity; replace if blown.
Reinsert the fuse and ensure it is properly seated.

4. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with manufacturer-recommended brake fluid if low.
Inspect the fluid for contamination; if dirty, perform a brake fluid flush.

5. Test ABS Module and Pump

Reconnect the battery.
Use an OBD-II scanner to perform an active test of the ABS module and pump.
Monitor for any error codes or abnormal readings during the test.
If issues persist, consider replacing the ABS module or pump as per the diagnostic findings.
