First, check your serial
Type your connector's serial number: 12 digits, starting with 9, printed on the OBD2 connector's label. The check runs in your browser: we don't store the number.
What it covers
- 12 V cars, EVs and hybrids.
- Heavy-duty trucks and buses. On 24 V systems the connector needs a 24-to-12 V converter.
- Special service functions. What the app does on each vehicle depends on its make, model and year.
- A 1-year license for US$109 or a 2-year license for US$149: the 2-year one works out to US$74.50 per year.
- The connector is not included: the license is digital and we don't ship anything physical.
Similar devices it does not fit
- Thinkdiag HML.
- MUCAR BT200 MAX.
- Connectors with letters in the serial number (e.g. 9TF…): they use the maker's own app.
If your serial starts with 97986, you have an original Thinkdiag: this is its license.
Phone or tablet requirements
- Android 7 to 13. On Android 14 or later it only works if the phone or tablet accepts 32-bit apps: if that's your case, message us the model before paying.
- Doesn't work on iPhone, iPad or computers.
- 2 GB of RAM or more.
- Free space: about 16 GB for cars, 8 GB for heavy-duty trucks and 7 GB for EVs.
- Bluetooth and an internet connection.
- A compatible OBD2 connector.
What you get and how long it takes
We activate in 1 minute to 8 hours from when your payment clears. You get your license details by WhatsApp and email, plus a purchase receipt. To complete activation you plug your connector into a vehicle and tell us on WhatsApp.
The license is tied to your connector's serial number and can't be moved to another device. That's why it gets checked before payment.
A note on the T-Code
An adapter that was already used with DiagZone stops accepting the T-Code for the maker's own app. Decide first which of the two apps you'll use on this device.
On an iPhone?
DiagZone is Android only. On an iPhone, the right option for the same connector is the Thinkdiag 2 T-Code, which renews the maker's own app.
Frequently asked questions
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.
Can I renew before it expires?
Renewals activate when the previous license expires. Message us a few days before and we'll have it ready for that day.
Can I move the license to another device?
No. The license is digital and tied to your connector's serial number; that's why we check it before payment.
Does it work on 24 V trucks?
Yes, with a 24-to-12 V converter for the connector. Without the converter the connector can be damaged.
How do I pay?
With PayPal or a credit or debit card; in most countries you don't need a PayPal account. Prices are in US dollars (USD). See payment methods for details by country.
