Flashing dash lights

[D&D]

My DK5310 would not start this morning, 20 F. Dash lights on, turn key, nothing. Went and got a jumppack, dash lights on, turn key and very light on the dash is now flashing. Tested battery and it has a bad cell (or two?). Came back with new battery, dash lights on, turn key and it starts.
From reading, all dash lights flashing is a critical systems failure. DTC codes will hopefully lead you to which critical system is dead
Just a heads up post because I’ve never seen this before on any brand.

I read a thread several months ago about low or bad batteries frying ECM's due to low voltage / high amperage through the circuit board.
It was concerning enough that I swapped out my 10 year old battery that had been cranking slower than usual.
Hope you get it straightened out.

New battery resolved my issue. Luckily, every light flashing was just a pulse quickener.

Does look like there should be a warning attached to not use higher amperage boost for jump starts.
