hi have just been told my rangie is showing a co-boss system fault, sorry not sure on spelling of it, anyone have any idea what that is
 
L322 I have not played with but basically the can system cuts down on wires by networking the different modules together, this allows modules to receive data from other modules.

Can Bus by it's nature the fault could be in one of the modules causing comunication errors.
mattstevenson2005 has posted something similar about this before and water in an ecu from memory or ask irishrover
 
Using textbook you can do a global ecu test this will show which ecu is not communicating thus allowing a fix most coman is steering angle sensor,abs mould and the headlamp unit wire chaffing is still not a regular issue
