Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and securely supported.

2. Scan for ABS Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any ABS trouble codes for further diagnosis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connector and inspect for dirt, corrosion, or damage.
Clean any debris from the sensor and its mounting area.
Reconnect the sensor and ensure it is securely attached.

4. Check ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage rating.

5. Examine Brake Fluid Level

Open the master cylinder reservoir cap and check the brake fluid level.
If the fluid is low, add the recommended brake fluid type (DOT 3 or DOT 4) until it reaches the appropriate level.
Inspect for any leaks in the brake lines or around the master cylinder.

6. Test ABS Module and Pump

With the ignition on, listen for the ABS pump to engage briefly when the ignition is turned on.
If the pump does not operate, further testing of the ABS module and wiring may be required.
If necessary, replace the ABS module based on diagnostic codes or failure status.
