2007 workstar with a maxxforce 10. I do not have my diagnostic laptop so I am only able to pull the codes from the dash.
Spn: Fmi:
8321 12
8146 7
878 5
2011 9From the Allison shift selector:
P0727
When/if if it starts, it will run for a few minutes and then die. While it’s running it will cut off and back on real fast. Similar to if you pull the idm or ECM fuse in the battery box and stick it back in real fast.

878 fault is for marker lamp circuit issue . Body controller controls this circuit.

8321 and 8146 , if active , are for egr valve and vgt actuator communication faults . They are both related to the same power circuit that feeds them. I would inspect the relays that are located on the main chassis harness on the driver's side under the wiper motor area . They will have purple wiring going to them. With the key on, unplug those relays one at a time to see if they are working.
