If the DME control module connector is pulled off with the ignition
switched on, for example, the orrboard diagnostic system can detect a
"CAN: bus or DPRAM" fault under certain circumstances.
1. Read out the DME fault memory. If the fault "CAN: bus or DPRAM
fault" is stored, check the wiring from the Tiptronic control module to
the DME control module
2. Check the wiring from Tiptronic control module pin 85 (or 86) to
DME control module pin 85 (or 86) for continuity, short to ground
8 and short to B+.
Note
If the wiring is OK and fault is stored in one control module only, the
fault can lie in another control module.
