Citroen C3 problems with CAN BUS

[electrones]

I freinds

I have C.C3 1.4hdi year 2002, engine 8HZ commanded by bosch edc16c34.
This car doesn?t work because ECU and BSI lost comunication.
DTCs present
U1000
U1003
U1113
U1118
P0500

I thought the problem was coming from the ABS, but I think it is not because I checked the connectors and wiring everything seems to be in order,
I need electric scheme and opinions to help me solve this problem.
Thankk in advance
Cheers

Hi M8,

You are rigth, abs unit should be the problem. These models are called full-can, Can lines start at bsi then goes through abs and ends at ecu unit.
you can do diagnostic seasons and matching keys but only by K line, inmo is running by can lines, if there is a problem in abs then will not be any comunications between bsi and engine ecu unit. Try to bypass can at abs conector and check if the engine starts.

Regards.
