Hello, maybe someone has a diagram for the diagnostic connector from the engine ECU, I care primarily about engine diagnostics. The car drives normally, but there is no diagnostic option. It also does not connect to any other module, the power supply on obd is. Regards

or maybe it's the tester's fault

It was checked on two Lexia (with and without an adapter), Launch, and Delphi Autocom. None communicated with virtually any module.

Communication cables behind the plug OBD whole? They are often cut into a thief

View of the socket from the wires: Pin 1, 4, 5, 6, 9, 12, 14, 16 is planted

Have you checked what CAN bus looks like on OBD 6 and 14 pins? Maybe there is just a problem in some connector to the fuse box (with the module) in the middle on the left, or in the box itself, because these wires probably go directly to it

No one will tell you anything else ...

If someone has a diagram for such a driver and diagnostic socket, I could even get along and incur any costs, pw

on the left is enough to connect to ecu

I think the computer is different, it has 2 connectors 53 pins and one 48 pins. I found the pins responsible for CAN connectivity. The cables go to BSI. BSI is connected to the OBD connector. Is there any possibility if the ECU does not have a k line, connect to the ECU bypassing the BSI?

The computer looks like the pictures.
Continental
SID208
S180129101 D.

Added after 14 [hours] 5 [minutes]:

I checked the beam, the CAN network is ok.
For diagnostics, I tried to skip BSI, cutting off the ECU and connecting them directly to 6 and 14 OBD, but I do not know if in this configuration all the power supplies on the ECU were available, because the CAN from the ECU was cut off from the BSI, but it was still impossible to connect to the ECU

Looking at your middle picture and plugin first on the right
5.39 power supply
3 Weight
10 and 11 can.

Sure, who did the engine overhaul and was left without a bonnet and plugs in the computer. Check if there is water in it

For me, Delphi connects to Jumper after choosing Fiat ducato.

Hey buddy, you can tell me how to count these pins because I have 4 rows and symbols from A to M in this plugin I have a similar problem

Topic summary

The discussion revolves around the difficulty in accessing engine diagnostics for a 2008 Jumper III 2.2HDI. The user reports that the vehicle operates normally but cannot connect to the engine ECU or other modules via the OBD diagnostic connector. Various users suggest potential issues, including faulty diagnostic testers, damaged communication cables, and problems with the CAN bus connectivity. Diagrams and pin configurations are shared to assist in troubleshooting, with specific attention to the connections between the ECU and the BSI (Body Systems Interface). The user also explores the possibility of bypassing the BSI to connect directly to the ECU. Recommendations include checking for water damage and ensuring proper power supply to the ECU.
