pinout and values for a siemens BSM -L04 -00

[Henk Verburg]

Hi everybody, can someone help with a pinout diagram and values for the above mentioned BSM as fitted to a Citroen C5R of 2005 vintatage with a 2 lt 16 valve engine. Both BSI and ignition ecu read clean on Lexia 3 so i want to check the 5v feed to the fuel pump relay in the BSM and from there to the injection ecu asthere is no power on the fuelpump. both feulpump and injectors read short to earth whitch to me is normal if the relays do not get their 5v trigger signal fom either the ignition or bsi ? Im soory if its a foolish question as i dont know petrol systems very well . I normally work on the big cummins and detroit systems . Thanks Henk.

Henk, I've ran off some circuit diagrams for you of the Starting and Injection systems, so look out for an email shortly. There is no access directly to the specific components - but the wiring diagrams should help you trace the connections.

In the interim, have a look here on the wiki for the main component code lookups to help you identify the components: they should be in numeric order.
