Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Retrieve and Clear Error Codes

Reconnect the battery.
Use an OBD-II scanner to retrieve ABS codes.
Note down any codes for reference.
Clear the codes and check if the ABS light returns after a test drive.

3. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Check the resistance of the sensors using a multimeter. Resistance should be within manufacturer specifications (usually around 1,000-2,000 ohms).
Replace any faulty sensors.

4. Check ABS Fuse

Tools Required: Fuse puller or pliers
Locate the ABS fuse in the fuse box (refer to the owner's manual for location).
Remove the fuse and inspect for any signs of damage.
Replace the fuse with one of the same amperage if blown.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness and connectors for damage or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace any damaged wires or connectors.

6. Test the ABS Pump

Tools Required: Scan tool with ABS functionality
Use the scan tool to activate the ABS pump.
Listen for any abnormal noises and check if the pump operates correctly.
If the pump does not engage, further diagnostics may be needed for the ABS module.
