Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and secure it with wheel chocks.
Disconnect the vehicle battery.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connectors by gently pulling them apart.
Visually inspect for any signs of wear, damage, or corrosion.
If damaged, replace the wheel speed sensor.

3. Check ABS Control Module

Locate the ABS control module, usually found near the brake master cylinder.
Inspect the wiring harness and connectors for any signs of wear or damage.
If corrosion is present, clean the connectors with electrical contact cleaner.

4. Test Wheel Speed Sensors

Using a multimeter, measure the resistance of each wheel speed sensor.
- Expected resistance: Typically between 1,000 to 2,500 ohms (check specific service manual for exact values).
If any sensor is out of specification, replace it.

5. Reassemble and Test

Reconnect all connectors securely.
Reconnect the vehicle battery.
Clear the C1441 code using an OBD-II scanner.
Conduct a test drive to ensure the ABS warning light does not reappear and the system functions properly.
