i cant even plug my diag in as it just keeps asking me to turn on the ign.and wont go any further
i could use some help with finding this "circuit 15 " problem regarding the diag connection.

This is a known fault for the petrol engines where water gets into the fuse box, but not listed on the diesel cars.


Circuit 15 is simple it comes from pin 4 of the direct injection N73 module, it goes to connector X18 cockpit wiring harness, and on to fuse 2 and 3 in the same box rated at 15 amp.

The fuse for the fan is f20 30amp

All of this is wired to the K40 SAM see if any water under it (take it out)

i'll try to locate all of that lot and have a prod.

this is one of those funny ones where it's only been back from the body shop for a week after new door,wings,tailgate,bonnet and a load of paint and i can't help wondering if it'scoincidental or whether they've disturbed or soaked something.

i appreciate your help

This is a known fault on the 202 but not so much on a 210. if the car was got wet under the bonnet, then any water near that SAM will stop all communication with everything else

every thing else seems to work malc

i just cant get the diag to recognize the ign on

and that fan staying on thing....maybe the two are connected..i don't know.
