why am I getting a C1201 code on my Toyota Corolla E210 (2019-2024)?

Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

• Locate the ABS fuse in the fuse box (consult the owner's manual for exact location).
• Remove the faulty fuse and replace it with a new fuse of the same amperage.
• Reconnect the battery.

3. Check and Repair Wiring and Connectors

• Visually inspect ABS wiring and connectors for any signs of corrosion or damage.
• Clean any corroded connectors with electrical contact cleaner.
• Repair or replace damaged wiring as necessary to ensure solid connections.

4. Test Wheel Speed Sensors

• Remove the wheel and inspect the wheel speed sensors for dirt or debris.
• Clean the sensors carefully using a soft cloth.
• Reinstall the sensors and ensure proper alignment.

5. Reset the ABS System

• Use the OBD-II scanner to clear the C1201 code from the vehicle's computer.
• Perform a test drive to ensure the ABS and traction control systems are functioning properly.
