ECU module programming guide using FDRS

[rugedraw]

i have not gotten the TcU update completed

What color is the TCU in FDRS? Any codes in the TCU or GWM? Did the TCU update come off the list in the "SW Updates" tab or is it still there?

im going to be starting another session here in a couple hours and I’ll let you know! I’ve only got today left on my 2 day license…
I know that the Tcu update is still under the sw updates tab.

This is my first time ever using this software. I don’t have a good understanding of how things work.. this is what I’m seeing. I tried to clear and retest and it failed. Does the truck need to be cranked ? It’s on a good battery charger.

You do need to clear those APIM/TRM DTCs before trying to update.

TCU and GWM green which is good. Click the orange APIM and let me see the code(s) that are in the APIM. I would just try the TCU update again from what I am seeing.

how do I clear them? I think I know how to run the test but not exactly sure how to clear the codes.

I didn’t see anything in the video about clearing dtc’s/codes. Just saw how to run the tests.

Sorry.....got tied up at work. That U3000 code is a problem. Click the APIM, and look for a procedure called the APIM configuration tool and try running that. A checksum failure I assume is some bad config somewhere.

just ran the apim configuration. That u3000 code popped up. Do you know what it means?

Clicking the Clear and retest will reset the DTC. If it comes back after clearing its still present.

Just for the sake of knowledge of anyone wanting to help or provide insight: His truck is on Sync 21146 which is the one right after the broken Sync software from 2021 trucks that requires the APIM and TCU to be updated at the same time. The dealer replaced his APIM on 8/19 and they seem to have programmed it correctly (PMI and selected no when FDRS asked if it was the OG module).

However, the truck was on Sync 21146 before they PMI'd it and still on 21146 after the PMI, so the PMI didn't seem to update it; it just programmed it with the same firmware the old one had.

He now has an APIM and TCU update showing. This would be the equivalent to OTA 2.6.0 that updates both APIM to version 22087 and the TCU in one shot.

I recommended he pull the battery for 20 minutes to hard reset everything and then try to update the APIM first to see if FDRS does it and then pulls the TCU update packet right after as it is supposed to. If anyone has any ideas, feel free to post them.

Typed in the fault code to chat gpt.. may not be reliable info but it says that it’s an interruption in power to the apim somewhere. It said to check fuses and pins for the apim

Is it worth the trouble to PMI it again? Have other modules been updated during this session that may change the outcome of a PMI? I saw some posts when I searched that DTC that said a PMI fixed the problem.
