Lightning Software Updates using FDRS

[Robob]

Be careful using a battery charger as a power Supply. The boost modes are not designed for hours of continuous output at the rated 50A. Most times it’s only 15-30 min and it’s not supplying a steady state of voltage or amperage.

IPMA updates can be 1.5-3.5 hours depending on your VCI speeds so I would not recommend any one use a charger in boost mode for flashing modules in FDRS

I'm very indecisive on what power supply to get. I've got about $100-$150 budgeted at the moment. Otherwise it'll have to wait until xmas shopping is done so I can see what damage that did.

The one above I shared is $149. I like it cause it just does what it needs to and that’s boost up the amperage. I’ve used it several times on my truck as well as other trucks that I’ve updated. Works like a champ and it’s simple.

That’s a good caution but I’ve had really good luck with the one I shared above. I have used it several times for well over 2 hrs doing ipma etc. updates. And it actually is very stable with output. I have put my meter on it and watched it and it it’s pretty solid. Does not get overheated. Now at the 250 amp mode yeah that’s only for quick starts. I normally leave on the 50 or 25 depending on voltage which I watch pretty close.

Today is the day I dive into the world of FDRS. The final piece, Clore power supply, showed up last night.

Just got hooked up and already need an assist. 3 modules orange. GWM, APIM, TCU. All say CMDTC present...hmmm i know i am not supposed to update anything unless all are green.

Go to the FDRS CLEAR & RETEST menu and select ALL DTCs and clear them all, then retest. You might have to do this twice.

You'll know that FDRS is clearing and re-testing because the screen will show three horizontal gray circles completing retesting, like clock face edges.

BTW as I remember You'll have to have the truck ON, either in Key On Engine Off or all the way ON during this function... I've done this so many times since 2022 that it's just muscle memory for me haha and I can't remember the exact screen layout anymore.

I have done a clear and reset a few times no change. I was told to disconnect the negative on the 12V for a bit then reconnect and try again...

Disconnecting the negative on the 12V can help, will not hurt... it resets "hung" modules. I've done it once in all my FDRS updates on several cars and trucks.

Do the clear and reset in between each module update also.

Sometimes there are DTC set that a particular update fixes. I had an issue where it wouldn’t clear the PSCM codes until the ipma and pscm modules were updated. Whatever was in the newer version fixed it. If you had a real serious DTC set that wouldn’t let the truck get into its programming mode the update would prob hang and or freeze.
FYI if FDRS ever freezes or logs out mid update don’t panic it’s good at recovering where it left off. I have had multiple freezes and server issues whilst updating and you can always recover out of it.
