how to resolve C1201 code in my Toyota Camry Eighth Generation (2018-present)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and a basic tool kit.
• Ensure the vehicle is parked on a level surface and the ignition is turned off before beginning repairs.

2. Inspect and Replace ABS Fuse

• Sub-steps:
  1. Locate the fuse box (usually under the dashboard or hood).
  2. Identify the ABS fuse using the diagram on the fuse box cover.
  3. Remove the fuse using a fuse puller or pliers and inspect it for continuity.
  4. If the fuse is blown, replace it with a new one of the same amperage (consult owner's manual for specifications).

3. Examine ABS Wheel Speed Sensors

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Remove the wheel to access the ABS sensor.
  3. Disconnect the sensor wiring harness and inspect the sensor for dirt or damage.
  4. Clean the sensor with brake cleaner if dirty.
  5. Reconnect the sensor or replace if damaged, ensuring a secure fit.

4. Test ABS Control Module

• Sub-steps:
  1. Disconnect the negative battery terminal to prevent electrical shorts.
  2. Locate the ABS control module (usually near the master cylinder).
  3. Use a multimeter to check for proper voltage at the control module connector (consult service manual for specifications).
  4. Repair any damaged wiring or connectors as necessary.

5. Clear Codes and Test Drive

• Sub-steps:
  1. Reconnect the battery terminal.
  2. Use an OBD-II scanner to clear the C1201 code.
  3. Start the vehicle and perform a test drive to verify ABS functionality.
