You must have a valid TouchScan or OBDwiz license to purchase this add-on. If you do not have a license then you can get one on the TouchScan page.

The Toyota Enhanced Diagnostics Add-on is designed to work with any scan tool that is based on the ELM 327 command set. An ELM 327 v1.4 or later scan tool is required to access body modules on newer vehicles. An ELM 327 v2.0 or later scan tool is recommended for accessing all modules. Please note that some ELM clone scan tools incorrectly report the version as v1.5 or later, but they do not contain the complete feature set required for accessing the additional modules.


Upon purchase of the add-on, you will receive an email with activation and download instructions. If you do not receive an email within one hour of purchase, please check your spam filter or contact us.
