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 prevent electrical shock.

2. Inspect ABS Wheel Speed Sensors

Tools Required: Ratchet set, torque wrench, multimeter.
Remove the wheel covering the ABS sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to check for continuity; replace the sensor if it shows an open circuit.
Reinstall the sensor and reconnect the plug, ensuring it is secure.

3. Check ABS Fuse and Relay

Tools Required: Fuse tester or multimeter.
Locate the fuse box (typically under the dashboard or hood).
Use a fuse tester to check the ABS fuse; replace it if blown.
Check the relay operation by swapping it with a known good relay.

4. Inspect Brake Fluid Level

Tools Required: Brake fluid.
Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the manufacturer-recommended brake fluid type.
Inspect for any leaks in the brake lines or connections.

5. Test ABS Pump and Module

Tools Required: OBD-II scanner, multimeter.
Use the OBD-II scanner to run an ABS self-diagnostic test.
If the module is faulty, it may need to be replaced.
For testing the pump, follow the service manual procedures to activate it while checking for proper operation using a multimeter.
