2018 peterbilt 579 - mrperkins - 05-23-2026
Hello.
I have a 2018 Peterbilt 579 with a MX 11 EPA 17. The aftertreatmen module does not connect (using JPro)
Connector has 12 volts and GND. Any ideas?
One quick question if I test for ohms across yellow and green wires on tbe connector it should read 60 ohms right?

If you still need help, find any oem aftertreatment harness sticker with part number on the truck. I will try to pull diagram for you.

The part number for the ACM is
A054G093
Question, does it have to be programmed for the truck?
