DiagZone license: price, compatible devices and activation
1- or 2-year license for cars, EVs and heavy-duty trucks. You check your serial number before you pay, and we activate in 1 minute to 8 hours.
What DiagZone is
DiagZone (also called DiagZone Pro) is an automotive diagnostic app for Android. It works with a compatible OBD2 connector, such as the Thinkdiag 2, and with an active license it reads and clears fault codes, shows live data and runs special service functions.
DiagPass is an independent reseller: we sell the license and activate it on the serial number you checked. We don't make the connector or develop the app.
What the license 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- or 2-year term, depending on the one you choose. There are no lifetime licenses.
