Coding

If the old Control Module is still accessible read/copy it's Coding to the new Module. In case this is not possible please contact us directly and we will assist you with the Coding Process.

Every inquiry on this topic has to include a full Auto-Scan as well as which parts have been replaced and why, also make sure the Auto-Scan includes the complete VIN of the vehicle in question.
