what is CVTC learning? on my scan tool app it says its incomplete

 

Variable cam timing, the rev-up engine has a learning procedure for the EXHAUST cams since those are also variable on the rev-up. The non-rev engine has a solid locked exhaust cam sprocket and no variable cam timing on it.

There is no learning procedure for the intake cam.

It's a really easy procedure to do the exhaust timing relearn, engine running, shift to neutral, release clutch, parking brake OFF (so this needs to be done on a flat surface or you'll roll away). Make sure the headlights, AC controller, window defroster, heated seats, etc are all turned OFF. Steering wheel pointed perfectly straight forward. Then just use a stopwatch and hold the engine at 1900 rpm for 20 seconds, use a stopwatch, give it a couple extra seconds.

Nothing flashes on the dash to tell you it's completed but if you are in NDS2, Consult-II, or another tool that monitors that kind of work support then it will switch to COMPLETED.

 

thats why im asking... i did that one already and it says completed but theres another parameter that says "CVTC learning : Incomplete"

im using the OBD Fusion and i paid for the enhanced diagnostics

 

I haven't used that app before, I'm guessing it's just misinterpreting something that isn't available. I'm sure the Nissan/Infiniti specific module doesn't have much that applies to the VQ35DE engine, same thing with the Torque Pro app Nissan/Infiniti module, they added a bunch of extra stuff that is mostly for the HR and VHR engine. The CVTC stuff is likely something to do with the VVL on the VHR engine.

 

ok perfect thank you, thats all i needed to know
