REV COUNTER OPERATIONAL DESCRIPTION

Operational Description

The engine rpm sensor K046 sends its own signal to the engine management control unit M010, at pins 99 and 100 of connector B (for the 2.0 petrol versions the signal reaches the engine management control unit at pins B1 and B2 connector C). The control unit, in turn, sends this signal, from connector A pin 47 (pin J2 connector A for the 2.0 petrol versions) to the instrument panel E050 - pin 17 connector D. The control panel receives power from control panel H090, at pin 10 of connector D. Control panel H090 receives power directly from the battery at connector B pin 17, via a line protected by fuse F53 and F01, housed in under-facia junction unit B002 and engine bay control unit B001 respectively.
