what does error code C1241 indicate for my Toyota Highlander Fourth Generation (2020-present)?

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the vehicle's battery to prevent any electrical shorts.
• Ensure the vehicle is on a level surface for accurate sensor calibration.

2. Inspect and Repair Wiring

• Sub-step 1: Locate the yaw rate sensor, which is typically found near the center of the vehicle under the center console or dashboard.
• Sub-step 2: Visually inspect the wiring harness and connectors for any signs of wear or corrosion.
• Sub-step 3: If damage is found, repair or replace the wiring as necessary. Use electrical tape or heat-shrink tubing for insulation.

3. Replace Yaw Rate Sensor (if necessary)

• Sub-step 1: If the sensor is faulty, remove it by unscrewing the mounting bolts and disconnecting the electrical connector.
• Sub-step 2: Install the new yaw rate sensor by reversing the removal process.
• Sub-step 3: Torque the mounting bolts to the manufacturer’s specifications (typically around 7 lb-ft, but check service manual).

4. Calibration

• Sub-step 1: Reconnect the battery.
• Sub-step 2: Use a professional scan tool to perform a yaw rate sensor calibration according to the manufacturer's instructions.

5. Final Check

• Sub-step 1: Clear the error codes using the OBD-II scanner.
• Sub-step 2: Start the vehicle and monitor for any warning lights or error codes.
