6.3. Using Your Autel Scanner for Diagnosis

Your Autel scanner is your best friend in this situation. Here’s how to use it effectively:

  1. Access Special Functions: Navigate to the “Service” or “Special Functions” menu on your Autel scanner.
  2. Locate Relearn/Calibration: Look for options like “Inertial Module Relearn,” “Accelerometer Calibration,” or similar terms.
  3. Follow On-Screen Instructions: Carefully follow the instructions provided by the Autel scanner. These usually involve:
    • Ensuring the vehicle is on a level surface.
    • Verifying the parking brake is engaged.
    • Keeping the vehicle stationary.
  4. Live Data Monitoring: Use the Autel scanner to monitor live data from the accelerometer sensors. Look for:
    • Unusual or erratic readings.
    • Values outside the expected range.
    • Inconsistencies between sensors.
  5. Component Testing: Some Autel scanners have component testing capabilities. Use these to test the accelerometer sensors and wiring for continuity and proper function.

6.4. Step-by-Step Relearn Procedure

While the exact steps may vary depending on the vehicle and Autel scanner model, here’s a general outline:

  1. Preparation:

    • Ensure the vehicle is parked on a perfectly level surface (within +/- 1 degree). Use a bubble level to verify.
    • Engage the parking brake firmly.
    • Turn off all accessories (lights, radio, A/C).
    • Connect a battery maintainer to ensure stable voltage (12.6V or higher).
  2. Access Relearn Function:

    • Connect your Autel scanner and turn on the ignition (engine off).
    • Navigate to “Service” > “Chassis” > “Stability Control” > “Inertial Module Relearn” (or similar).
  3. Initiate Relearn:

    • Follow the on-screen prompts to start the relearn procedure.
    • The scanner may instruct you to enter specific values or confirm vehicle information.
  4. Calibration Phase:

    • The Autel scanner will guide you through the calibration process. This often involves a series of steps where the scanner measures sensor output at different orientations.
    • During this phase, it is CRUCIAL that the vehicle remains ABSOLUTELY STILL. Any movement will cause the relearn to fail.
  5. Verification:

    • Once the relearn is complete, the Autel scanner will display a confirmation message.
    • Clear all DTCs.
    • Perform a short test drive to verify that the ESC and other systems are functioning correctly and that no warning lights reappear.
  6. Troubleshooting and Validation:

    • If the relearn fails, carefully review all steps.
    • Check the sensor connections and wiring, as well as battery voltage, then re-attempt the procedure.

6.5. Advanced Troubleshooting

If the basic relearn procedure fails, consider these advanced troubleshooting steps:

  1. Wiring Inspection:
    • Visually inspect the wiring harness connected to the accelerometer sensors and IMU. Look for:
      • Damage or chafing.
      • Loose connectors.
      • Corrosion.
    • Use a multimeter to check the continuity of the wiring and verify that there are no shorts to ground or voltage.
  2. Sensor Replacement:
    • If you suspect a faulty sensor, replace it with a new, OEM-quality sensor. CARDIAGTECH.NET can help you source reliable replacement parts.
    • After replacing the sensor, repeat the relearn procedure.
  3. Module Replacement:
    • In rare cases, the IMU or related control module may be faulty and require replacement.
    • This is a more complex procedure that may require specialized programming or coding.
  4. Software Updates:
    • Ensure that your Autel scanner has the latest software updates. These updates often include bug fixes and improved calibration routines.
  5. Data Parameter Checks:
    • Sometimes the problem lies in other modules that provide information to the IMU
    • Check data parameters related to wheel speed sensors, steering angle sensors, and the ECU.

6.6. Validating the Solution

After completing the repair, it’s essential to validate that the “Inertial Module Offset Learn Failed” error is resolved:

  1. Clear DTCs: Clear all DTCs again.
  2. Test Drive: Perform a thorough test drive under various conditions (straight line, turns, braking) to ensure that ESC and other systems function correctly.
