Hello all, I have an Australian delivered 2012 Mack Granite MP8 Engine with SCR. The ACM unit seems to have suddenly lost all power, the DEF Tank Level Gauge is reading empty even though its full to the brim, the dosing pump is not operating and I have fault code SPN 2061 FMI 19 - Relating to loss of power to the same system. The Australian delivered trucks don't come with a fuse panel layout for either of the two fuses locations in the cabin. Just wondering if anyone may be able to help me with where to check if the ACM is getting power? The inline fuse in the chassis is fine and no power is down there. EDIT: It seems when someone takes the power and earth wire off for the adblue system in the base of the cabin, and cable tie them together instead of separately that someone put them back on together instead of one to power and one to earth.
