ECU module programming guide using FDRS

[TJSparky]

I don't see an APIM update yet for my 2021 302a but there are a few door module updates.

Have a new APIM showing -- guess the GWM update was ready'n for an update after all.

Also an update showing for the DC/DC converter too

Old: APIM 1049 / 23291 software PN PU5T-14G676-CC
New: APIM 1270 / 24127 software PN PU5T-14G676-EC
@rugedraw

DC/DC software went from ML38-14D459-AB to PZ18-14D459-AD which is the same software on 24s that still retain the exact same DCDC

Thanks for posting. I did updates on Tuesday with a 2 day license. Had the same DC/DC update but no APIM at the time. Saw your post late last night and pulled out FDRS and I found I now had the APIM update. Built the USB last night while my license was still valid. Installed this morning without issue.

The weather has been to nice to start updating my truck but thanks to Francine today is the day. I want to try and update my 21 Expedition while I'm at and get more familiar with the software so I purchased a month license. ABS module went quick, the IPMA has been running for over an hour at this point.

I made a check list of things to do and the order of updates based on post here but one thing I almost missed is you have to turn off the 30 min idle timeout each time you cycle the ignition.

Great that it's going well for you ?. If you hook up a decent power supply (20A or better @ 13.8V), you don't need to run the truck, just accessory mode and the 30 minute timeout then doesn't come into play ?

 

[FI300]

I do have a 20 amp charger with power supply mode connected. I have heard conflicting information on whether the timeout still needs to be disabled so I didn't want to take a chance. Its also sitting at 13.7 so not quite there.

The timeout has no impact. No need to do anything. CAnbus updates override it.

Thanks for confirming.

Thanks for confirming.

Make sure all your power saving and screen saver settings are OFF in the computer though.. THat has been a issue for many

Looks like everything is updated except the locked BCM update and I have a ACM update that wont clear. Wasn't that bad but you do have to baby sit it. I guess I missed the part about having to have the engine running for the USB updates and I wasn't expecting to have to run the engine. Luckily I have an exhaust fan I haven't pulled out in years because I was in the garage.

I do have a DTC, it was present before and still is.

Went for a drive just to make sure everything was good. Went to back into my very tight basement garage, turned off reverse break assist like I always do and no Ding Ding warning that I turned it off, Hallelujah! That in itself was worth it.

Give it some time. IPMA can take a bit to settle down after it's been updated. Is everything working as it should?

I recently started this entire project, I have a 21 Lariat I recently purchased that had the gridlocked OTA update, no sync versions, etc, so I bought the Mongoose, 2-day license for FDRS, and made it through most of the modules, saving the APIM update for last. I ran into the same issue as others where the update wouldn't kick off, once it popped up saying the update was downloading, but wouldn't make any progress and was stuck at 0% downloading. I wanted to go the TSB 22-2117 route, but on my FDRS v.41.5.2, in the multi-module, I don't have the Module Update Repair application. Has anyone ever had that happen? I've tried searching for it but have had zero luck finding the module update repair.

@rugedraw ... is the BCM update still locked out? The reason I was asking is that @deagle2008 did a BCM update with FDRS. I suspect it was an older update tho.

As far as I know, it's still an issue.

I just re read his post...it was the BCMC that worked...not the BCM.
