what does it mean if my Toyota Camry XV50 (2012-2017) has a C1201 code?

Solution

1. Preparation

• Gather necessary tools and replacement parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

• Locate the fuse box, usually found under the dashboard or under the hood.
• Remove the ABS fuse and visually inspect it for any signs of damage.
• Replace the fuse with a new one of the same amperage if damaged.

3. Inspect ABS Wheel Speed Sensors

• Raise the vehicle using a jack and secure it with jack stands.
• Locate the wheel speed sensors at each wheel hub.
• Clean any dirt or debris around the sensor.
• Disconnect the sensor connector and check the wiring for damage.
• If damaged, replace the wheel speed sensor.

4. Test ABS Control Module

• Reconnect the battery and turn on the ignition without starting the engine.
• Use a multimeter to test the ABS control module for voltage.
• If voltage is not present, inspect the wiring harness for breaks or corrosion.
• If the module is faulty, replace the ABS control module following the manufacturer's instructions.

5. Reassemble and Reset System

• Reconnect all connectors and ensure everything is secured.
• Clear the C1201 code using the OBD-II scanner.
• Lower the vehicle and perform a test drive to ensure the ABS system functions correctly.
