How to control Citroen C5 X7 cluster from CANBUS

[@gerigesquiere66]

I have been looking for the IDs on my Citroën C5 for years. I have the Microchip CAN analyzer. Where can I find the IDs? Many thanks for the video.

@@gerigesquiere66 it all depends on what ID you need. generally the network where the cluster is has many devices. the simplest connection is to the radio plug.

Good job! it is not usual to find reverse engineering work about Citroen C5 X7. I have one too. Any chance you know what is the unlock key of the cluster to read or write configuration with Arduino? I know IDs command ">75F:65F" but without unlock key nothing to do with it

not really, but I assume you check car pin? I would suggest you download eeproms from internet, compare difference. the odometer adres is easy one, next you have option settings/coding for this ypu can read your eeprom then code via lexia some option and read again to compare. you should be left with region that is different in eeprom that is not odometer or options.
