Engine Code CRTC

Post by danicalo@libero.it » Thu Dec 18, 2025 3:46 pm

Hello Code in object is not present, so app doesn't shows oil ash residue and soot mass measured. My etiquette with LN Number is writing engine code CRT, can I use the code CRTD? Is it possible?

Thanks.
Best regards.

In the app you can select an engine group, no a single engine code. This because many engines share the same diagnostic setup so I've grouped them.
If you select a group not suitable for your engine, you simply have "nd" values in the fields, but you risk nothing because for a request of a missing parameter, the ECU simply answer with NO DATA.
This means that you can try every engine group, also if it doesn't contain your engine code.

For your specific question about CRTC and CRTD, I can answer that almost always, engines with the same first 3 characters share the same diagnostic setup because the last character is usually related to the power variant only.
