Year of Manufacture *: 2002
( Optional ) Engine Code or CC: 3.0d
I also have no communication with air suspension/ immobiliser/air bag and switching (h/seats)modules despite power and grounds present and probably more on the k bus line although i am limited to which modules i can access as i have only got a modis and a friends launch the instument cluster has codes
87 k bus,
BE internal error light module,
bd internal error instrument cluster,
as the modules with no comms are all linked via the k bus i have scoped the k bus at the modules concerned and get a constant 3.3 volts disconnecting some modules on the k bus this rises to around 5 volts, according to wds bmw this should be 12v switching to 0v in 5ms to 30ms messages
Ok so at the minute im working on if i can restore the k bus i can get comms with affected modules to start looking at the problems iv got but secretly hoping that all the problems are linked to the k bus being down
Do you guys think im going down the right path do you have any suggestions would you agree with my thoughts /findings so far any help here would be great as im getting a little over my head at this point
thanks lee
