Programming
2020 Nissan Altima Advance 2.5L (PR25DD) (RE0F10D) — 1N4BL4CVXLC155629

Hey, all!

I've done some digging and emailed Tweddle, but wanted to see if anyone has run into this. I showed up to program a donor ECU for this 2020 Altima yesterday, which the customer pulled from the same year/model vehicle. Grabbed the calibration for the part number, then went to flash the thing and got this error:

N_UDS_STEP1_RC22

Anyone know if this is a mismatch code or something else?

Thanks in advance for your help!

What is your connection to the vehicle? A J box? I ask as UDS is in that line. kvaser​.​com/about-can/can…

MaxiSys VCMI and DS Nxgen. The TCM programmed fine with the Nxgen.

LOL. You aren't going to be able to program that vehicle with v3​.​xx NERS. You will need v4​.​xx and secure access at a minimum. You will also need the secure gateway workaround patch cable since you're not using the Consult. I'm also not certain that late model Nissan ecms are reusable. I have rewritten the VIN on 2017+ Vehicles, so 2020 might be okay.

Used? No go on that. If it was older you could click a couple buttons on certain scan tools and get it to work. Not that one

I've never had anyone at Nissan get back to me in less than a week.

It has been a while since I needed to contact Tweddle support but it probably was before COVID, seems as if everyone blames their inadequacies on COVID these days.
