Solution

1. Preparation

Gather all tools and parts required.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect ABS Fuse

Locate the ABS fuse in the fuse box.
Use a multimeter to check for continuity.
- If the fuse is blown, replace it with a fuse of the same amperage.

3. Check Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Inspect for dirt or debris; clean if necessary.
Disconnect the sensor connector and visually inspect for damage.
Measure the resistance of each sensor using a multimeter; refer to the service manual for specifications.

4. Inspect Wiring and Connectors

Follow the ABS wiring from the wheel speed sensors to the ABS control module.
Look for any signs of fraying, corrosion, or disconnection.
Repair any damaged wires and ensure secure connections.

5. Test ABS Control Module

Reconnect the battery terminal.
Use the OBD-II scanner to clear the C1241 code.
Perform a function test on the ABS system while monitoring with the scanner.
If the module is faulty, replacement may be necessary.
