Each time the battery or the DME/LH control unit plugs are disconnected, system adaption must be performed. This is done after reconnecting the battery or the DME/LH control units. If adaption is not performed, the engine idle RPM could drop too low and cause the engine to stall with closed throttle.
For system adaption procedures refer to 944 or 928 Workshop Manual, Volume 1, page 03-15.
