In my previous post I was looking for a schematic depicting the battery cable layout for a 2016 Freightliner Cascadia Evolution with a DD15 motor, last six of the VIN are HF6666.
Well, now the batteries are back in place, and the motor seems to crank right up without any problems. However, I’ve now encountered one or two electrical issues which I don’t understand.
A. The ID lights located on the roof of cab won’t stop flashing. (Possible theft protection?)
B. The front turning signals are flashing along with ID lights.
C. The rear tailights aren’t working. (possible blown fuse or bad bulbs?)
D. Rear turning signals are not flashing along with front signals and ID lights. (Appear to be dead)
I’m guessing that the flashing lights must be due to a malfunctioning relay, most likely located within the fuse box inside the cab? Or could there be something else causing this problem, such as an anti-theft mechanism?
So, now I would like to locate diagrams showing the layout of the fuse and relay locations for the below boxes.
1. SAM Cab box
2. Powertrain PDM (PT-PDM)
3. Powernet Distribution Box (PNDB)
4. SAM Chassis box.
I’m guessing that problem is located in number one or number four in my above list. I’ve tried contacting the dealership, but they said that their diagrams don’t show which fuses are located in which spots inside the boxes. Any info greatly appreciated.
