• ECM converts the pulse signal provided by the crankshaft position sensor to an engine speed signal and
transmits it to the unified meter and A/C amp. with CAN communication line.
• Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.
• The unified meter and A/C amp. receives the engine speed signal from ECM with CAN communication line
and transmits it to the combination meter by means of communication line.
• Combination meter converses engine speed signal to the angle signal, and commands to tachometer.
