This is a Hymer camper van which is proving to be difficult to identify accurately as they change the chassis number. It appears to be a 316 chassis. Anyway, it doesn't start unless you disconnect the battery and reconnect it with the ignition on. Otherwise the dash displays a start error fault. I can't talk to the gearbox ECU and am having problems talking to the engine ECU, immobiliser etc. It will only communicate when I get the engine started using the above method. I suspect a possible gearbox ECU but I can't locate it! Can anyone point me in the right direction? I was going to start off by disconnecting it and see if I can then comms with the other ECUs on the vehicle. The other issue it has is that the condenser fan runs erratically with either just ignition on or engine running. I can hear the relay under the passenger seat clicking away merrily to its self. I suspect these faults are related.
