Cat man. I am getting a 253-2 fault code after I replaced

Customer Question

Hello cat man. I am getting a 253-2 fault code after I replaced the ecm. I saw one of your earlier posts where you mentioned that it could be missing injector trim files. I am currently missing 4 of the files. Would you be able to send me the files if I gave you the serial number. It is a C15 MXS36093

Thanks for asking your question. I can help you with this.

Yes I can get you the trim files. But unfortunately I will need the 12 digit serial numbers off the top of each injector. Sorry. I can not get them from the serial number. I am sorry.

If you can get me each serial number and your email address, I will send you the trim files you need.

These 4 are not coming up as good numbers. Please recheck these. Serial numbers are 12 digits.

One more question. It is asking me for a injector confirmation code. What number do I input here? I am guessing it is a number on the injector, but which one?
Expert:  Cat Man replied 1 year ago.
That is the 4 digit number on the injector. It should be near the 12 digit serial number.

okay thank you

Thank you so much. I was able to clear the code with those files. One last question a code of 22-13 Engine Speed Signal Calibration Not Performed(42) showed up. Do you have any suggestion on how to clear this code?
Expert:  Cat Man replied 1 year ago.
You are very welcome my friend. I am happy I could help.
You will need to calibrate the timing by inserting a timing probe into the engine and connecting it to the ECM. Then under the service screen of ET is the calibration screen. Sorry. I wish there was an easy way to clear the code. After calibration, the 22-13 code will go away.
