2004 clio 1.2 16v multiple faults caused by ?



ok, so we bought the car with immobiliser problem.
the previous keeper drove it home and it developed a missfire, got home and would not restart
immo light is on solid and key turns the engine over for 3-5 seconds.
no fuel pump priming
when we clear fault codes it come straight back with electronic steering fault and airbag fault
results on renault clip are :

abs missing
communications missing
petrol inj comp missing
steering angle sensor missing

faulty segments are 2 and 5

comms link obd
>>>>0>>>>>E133>>>>>>6>>>>>>645>>>>>>>5>>>>>>R107>>>>>>>2>>>>>>>120
...............DIAG................?????...................... UCH.......................?????.......................... ECU--ENGINE
whats are E133 AND R107 AND WHERE ARE THEY ?

everything seems to work apart from what i have mentioned above, i can read all the vin and settings from the uch but i think its something common between the ecu abs and steering system R107 maybe ?
cleaned and checked all relays and fuses, no greeness anywhere
anyone got any ideas ?

Yep and the above tells you quite clearly what's actually not happening and hints at what is needed to fix it.

Google CLIP training and learn to use the tools properly ;-)

I'll give you a subtle hint... the comms line between the UCH and ECU is not allowing the CAN signals thru hence the solid red light and failure to start. Check the lines between the two component codes (645 - 120 via connector R107) for breaks and fix them.
 
thanks for the advice mick, what i need now is a pinout between UCH and SIEMENS SIM32 ecu
autodata and tollerance only seem to show 2 plug schematics for the magnette marrelli systems
 
anyone got the wiring diagram for one of these ? i have searched all over and keep reading the same request but never seen a download link !
 
thin red wire 12v relay end and 1.2v at ECU
probed either side till i found break.

running but found a low rev missfire when moving off :(
