Hello,

i have a problem with mentioned truck, it gives error 30 and 330 on the eco smart display at startup,and nothing works, error 30 is VMN LOW, but 330 is nowhere to find, but when i connect zapi tester it gives some alarm CAN BUS KO PUMP on drive controller (dual AC-2) and on the other pump controller MC TRACTION KO (AC-2)

Does anybody have any clue what to search? All the pot's are ok,switches working, motors are ok, no shorts on outputs...
