JCB 50Z-2 U1917-2F

[Munteanu]

Hello! I have that error U1917-2F.
1. cable was verified
2. ecu was replaced

Vehicle setup and Immo (Immobilizer setup) have already been done.
I want to know if there is any slot, compartment, or switch that cuts off the CAN communication. This is for a JCB 50Z-2.

That U1917-2F is a CAN communication fault. Since you've already replaced the ECU and verified the cable I'm wondering if you've checked the CAN termination resistors. They're usually a pair of 120 ohm resistors on the bus ends and if one burns out or comes loose you get exactly this kind of dropout. Do you have a photo of the wiring harness where it connects to the ECU. Also what does the diagnostic read when you get the fault.
