Error Codes $0333, $0281, $0101, $0537

These codes can occur for a few reasons, but most of the time it's caused by aftermarket electronics or tuning that was previously installed on the vehicle.

To troubleshoot this issue, please proceed with the following:

1) Disconnect/Uninstall any and all aftermarket electronics (they can be reinstalled later).
2) Ensure that only the AutoCal is connected to the OBD port during the tuning process and not split with another device.
3) Disconnect the following fuses:
      - TBC Batt (LLY)
      - TBC Ignition (LLY)
      - Info
      - Radio
      - Radio AMP
      - SEO1 (LB7)
      - SEO2 (LB7)

If the code or issue still exists, we can attempt to flash the ECM in passthrough mode with the use of a windows based laptop and internet access.

In the unlikely even that we cannot get the ECM to accept the flash in passthrough mode, we can have you send your ECM into our facility to be bench flashed. We will mail it back to you tuned and ready for installation.

Please reach out to as at (337) 485-7070 for further assistance.
