Purpose
The tachometer notifies the driver of the engine speed.
Function
The instrument cluster controls the tachometer needle based on the engine speed signal from the PCM and displays the engine speed per minute.
Construction
An analog needle display tachometer with a stepping motor mechanism has been adopted.

Operation
The instrument cluster receives (1) the engine speed signal from the PCM when the ignition is switched ON (engine on).
The instrument cluster moves the needle based on the engine speed signal and displays (2) the current engine speed.

Fail-safe
Function not equipped.
