Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush.
Ensure the vehicle is on a level surface and the ignition is turned off. Disconnect the battery to prevent any electrical shorts.

2. Inspect ABS Module and Wiring

Steps:
1. Locate the ABS module (typically near the master cylinder).
2. Visually inspect the wiring harness for frays, corrosion, or loose connections.
3. Clean any corroded connectors using a wire brush and contact cleaner.
4. Reconnect any loose wires and ensure all connections are secure.

3. Test Battery Voltage and Ground

Steps:
1. Use a multimeter to check the battery voltage; it should be around 12.6 volts.
2. Inspect the ground wire connected to the ABS module for continuity using the multimeter.
3. If the ground is faulty, repair or replace it as necessary.

4. Inspect Wheel Speed Sensors

Steps:
1. Locate each wheel speed sensor and visually inspect them for damage or dirt accumulation.
2. Use a multimeter to check the resistance of each sensor; refer to the service manual for specifications.
3. Clean any obstructed sensors and connectors, ensuring a good connection.

5. Clear Codes and Test Drive

Steps:
1. After repairs, reconnect the battery and use the OBD-II scanner to clear the C1201 code.
2. Start the vehicle and perform a test drive to check for any warning lights and to confirm normal braking function.
