OBD2 diagnostics for Jeep
What Final OBD reads and does on Jeep cars. The basics work on any car with OBD2; the rest depends on what each control unit answers, and here is what the app knows about the make and its 11 models.
What there is for Jeep
Figures for the whole make. On your car the app shows what its control units answer, no more and no less. The needle shows which version each feature is in.
- Free
Gauges and engine faults
Standard OBD live data and engine faults explained, free with Free.
- Pro
Faults from every control unit
Engine, gearbox, ABS, airbag, body and the rest, explained, with how the car was running when they happened, and cleared once fixed. 16,425 codes specific to the family, on top of the generic ones.
- Pro
Roadworthiness verdict
What the Spanish ITV test centre reads through the OBD socket, judged by its official manual: pass, fail or something still to read.
- Pro
Make specific data
1,189 readings that standard OBD doesn’t give and that the make stores its own way, depending on each model.
- Pro
Mileage check
The mileage stored in the control units, next to the dashboard figure. If one of them holds more, it’s the classic sign of a clocked car.
- Pro
Service functions
1,166 service and maintenance jobs the car expects to be done from a diagnostic tool, on the control units that accept them.
- Workshop
Component tests
4,601 tests to run a part from your phone and see whether it responds, without taking anything apart.
- Workshop
Control unit adaptations
495 adaptations to switch features on or off or tell the car you’ve replaced a part. The app reads every value back before and after.
- Workshop
One tap changes
17 ready made changes per model, without having to know which value goes where.
Jeep models
Each model with its years and engines, and what can be done on it. A yes means the app has it for that model; on your car it shows up if the control unit answers.

The security gateway
Since 2018, Stellantis group cars have a security gateway so that only the manufacturer’s tools can write to the control units. On those cars Final OBD reads everything, but it may not be allowed to clear faults or change anything. Older cars don’t have it.
Can I clear the fault codes on my Jeep?
Yes, with Pro: it reads and clears the faults in every control unit that answers, not just the engine. Clear them once the fault is fixed; if it’s still there, it comes back. On models with a security gateway they are read all the same, but the car may not let you clear them.
Can I reset the service light or do the maintenance on my Jeep?
With Pro, the app has 1,166 service jobs for this make. Which ones work on your car depends on its control units, and the app only shows you the ones yours accepts.
Which OBD2 adapter do I need?
Any ELM327 type will do for the basics. For every control unit and the Workshop features, a good one, like a vLinker or an OBDLink. It’s all in the adapter guide.
Does it help with the roadworthiness test?
Yes, for the OBD part. It reads through the socket what the Spanish ITV test centre reads and tells you whether you’d pass under its official manual. Full details in the ITV and OBD guide.
