🐞 Symptom

🔍 Cause

Airbag system variant coding may fail in the following cases:

  • A vehicle-side fault in the airbag system
  • A mismatch with EOL (End of Line) coding information

To resolve the issue, check the details of the DTC. Once the root cause is identified and corrected, you can retry the variant coding.

🛠️ Solution

  1. Check the airbag fault code and click the DTC Code.

    Step 1: DTC Code screen

  2. Click on "DTC Status".

    Step 2: DTC Status screen

  3. Resolve the cause listed in the Information Code.

    Step 3: Information Code

✅ Reminder

Once the cause has been resolved and the DTC cleared, you may retry ACU variant coding successfully.
