Hello John,
I am surprised you managed to program in the injectors as when I tried it on the X trail I used it on , it kept failing(using Carman scan lite). On the last one I replaced the SCV on , I managed to get it to readapt using the manual method as I previously described, although it does state that when the fault is cleared(using the consult), the relearn procedure is reset anyway.I initially just tried clearing the code, which did clear, but when I drove the vehicle it came back the same as yours & went into limp mode, but after using the manual method the vehicle drove fine without logging any faults, so it may be worth trying before you take it to the dealers.
I also didn't have any option to carry out any adaption on the Carman scan when I used it on the X trail before the onethat I last did.There was only the option in work support to be able to code the injectors, the same as on the multiscan. One other function I thought was usefull, was the cylinder balance test where you could knock out one or more injectors at a time, which could possibly have shown up an underperforming injector.You can also adjust the fuel pressure , which allows you to see how low a pressure it will continue to run at & also how much pressure the pump will create.
Below are the instruction for X trail YD22

No Tools
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once.
2. Wait at least 10 seconds and then turn it ON (engine stopped) again.
3. Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to
EC-997, "HOW TO SWITCH DIAGNOSTIC TEST MODE" .

If the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.

The following data are cleared when the ECM memory is erased.
– Diagnostic trouble codes
– Freeze frame data
– Fuel pump learning value
– Others
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.
