The SAM chassis is prone to failure. If you put a laptop on it with the DDEC software, you will see faults wrapped around different fuses blown. Mine is showing the water separator and trailer light fuses shorted or blown and the fuses are fine. I'm going to change it today and the 2023 off the shelf price at FL is around $1000 with a $250 core charge.

Today I had the problem of fender lights and rear brake lights, on a Freightliner M2 Box truck flashing like hazards. ABS Light flashing on and off, then stayed on. DEF light indicating 1 red bar blinking. Had 3/4 tank. Truck also wouldn't turn over at one of my stops...got it started and just kept it on at stops...also just dealt with the lights blinking. Lost directionals, just brought it back to the warehouse, yeah I know, shouldn't have drove it. Twas embarrassing, but I'm just glad I'm home. Lmao.

Does that also affect the trailer lights not coming on

My truck having the same problem now I orders the Sam chassis online ( same numbers ) does it need to be programmed or just plug and play?

Thank you for the video.
Freightliner cascadia.
during my driving my truck, it's happened suddenly the whole lights got off dashboard inside lights and outside lights and after 3 seconds back on its happens 3 times and I felt the truck engine about to shot down also. beside this when I'm not driving and engine off, I hear clicking sound for sometimes from the same place, the one you showed under the hood.

The hazard module switch was the problem on my 2014 ....But the issue was the same like in this video.

[simarbhangusingh]

Did you program that ecu before putting on ?

[shaqwilliams]

My truck is a 2013 cascadia and doing this as well. Changed the module with the hazard button but that didn’t work. Then changed the central gateway module and that didn’t work. Looking to change the Sam chassis next.

Pndb Switch is the main problem. $450 for the main PNDB MODULE in my area . Idk about yours.
But Inever spend money on diagnosis.i always buy that PNDB box and change for 3 cascadia including they randomly shuts off and turn back on by themselves at highway.blinking lights like yours.

A friend of mine got a 2012 Freighliner cascadia DD15 engine, after he deleted the Def in some shop in Chicago, he drove about 200miles and he heard some knocking on the engine with a lot of smoke coming out of the exhaust, he drove about 10miles to a truck stop and fire started to come out of the exhaust pipe, the Def system was very hot and the plastic near that was melting, and the cylinder N5 had no compression.
Any ideas about what happened please?
Any thoughts please?
