Thinkdiag renewal with a T-Code
A T-Code is a code that renews the maker's own app on your Thinkdiag for 1 year. We send it in 1 minute to 8 hours from when your payment clears.
What a T-Code is
When the subscription on your Thinkdiag or Thinkdiag 2 expires, you need to renew it to keep using the diagnostic software in the maker's own app. A T-Code is the activation code that adds one more year: you buy it once and enter it in that app.
That app runs on iPhone and Android, so a T-Code is the option for iPhone users.

How it arrives and how long it takes
You pay on your device's page (Thinkdiag 2 or original Thinkdiag) by card or PayPal; at checkout you enter your serial number. If your adapter is second-hand or you're not sure whether it was used with DiagZone, message us on WhatsApp first.
We send the code by WhatsApp and email, in 1 minute to 8 hours from when your payment clears, along with a purchase receipt.
The renewal is also sold inside the maker's own app. With DiagPass you pay in US dollars by card or PayPal and chat with us on WhatsApp in English, Spanish or Portuguese.
Frequently asked questions
What is a T-Code?
It's a code that activates 1 year of software in the maker's own app for your Thinkdiag. You buy it once and enter it in that app.
How do I know if my adapter was already used with DiagZone?
If you bought it new and have only used the maker's own app, it hasn't been used with DiagZone. If you bought it used or you're not sure, message us with the serial number before paying and we'll go over it with you.
Is the renewal also sold inside the maker's own app?
Yes. You can also buy the renewal inside the maker's own app. With DiagPass you pay in US dollars by card or PayPal and we chat with you on WhatsApp in English, Spanish or Portuguese.
Does DiagZone work on iPhone?
No. DiagZone is Android only. If you use an iPhone with a Thinkdiag or Thinkdiag 2, the right option is to renew the maker's own app with a T-Code.
How long does activation take?
1 minute to 8 hours from when the payment clears. We'll let you know on WhatsApp. With DiagZone, activation is completed once you plug your connector into a vehicle and tell us.
