Nissan OBD2 Scanner & Diagnostic App

Carista turns your phone into an OBD2 scanner for Ford: full-system Nissan diagnostic, Nisssan-specific fault codes, Nissan TMPS registration, and customization across 45 model lines.

About


Carista is a Bluetooth OBD2 scanner and phone app that gives Nissan owners full-system diagnostics, live engine, wheel speed, battery and HVAC data, service tools like TPMS registration and EPB service, and customizations like coming-home lights duration and the auto headlights threshold — across 45 Nissan model lines — without a trip to the dealership or a laptop-based tool like Nissan CONSULT.

What can you do with Carista & your Nissan

Carista reads and clears Nissan fault codes, streams the same live data a technician sees, including turbo and DPF, and handles the Ford diagnostic checks and settings a dealer visit would otherwise be needed for.

12 of the most common Nissan codes

These are standard SAE-defined diagnostic trouble codes that turn up most often across Carista's Nissan lineup – the same codes a dealer's scan tool would show.

U3003-16

Battery voltage dropped too low while a module was running, usually a weak or old battery.

P0420

The catalytic converter isn’t cleaning the exhaust as well as it should, usually because it’s worn out

P2463

The diesel particulate filter is clogged with soot and needs a regeneration (cleaning cycle).

U0140

A module lost contact with the body control module, which runs lights, locks and wipers.

P0101

The sensor that measures air coming into the engine is reading implausible values, usually because it’s dirty or failing.

U0415

A module received invalid data from the ABS (brake) module, often after a wheel-speed sensor fault.

P0300

The engine is misfiring on several cylinders at random, often from worn spark plugs, bad ignition coils or a vacuum leak.

P0171

The engine is getting too much air for the fuel, usually because of a vacuum leak or a dirty air intake sensor.

P0420

The catalytic converter isn’t cleaning the exhaust as well as it should, usually because it’s worn out.

P0442

There’s a small leak in the fuel vapour system, often a worn fuel cap seal or a cracked hose.

P0128

The engine is taking too long to warm up, almost always because the thermostat is stuck open.

P0299

The turbo isn’t producing enough boost, typically from a boost leak or a sticking wastegate.
