Purpose
The speedometer notifies the driver of the speed at which the vehicle is traveling.
Function
The instrument cluster controls the speedometer needle based on the vehicle speed signal from the PCM and displays the current vehicle speed.
Construction
An analog needle display speedometer with a stepping motor mechanism has been adopted.

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

Fail-safe

Resistance inspection
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.

Awd Control Module Inspection
NOTE:
AWD CM terminal voltage can vary depending on measuring conditions and vehicle
aging, resulting in misdiagnosis. Therefore, it is necessary to perform an overall
inspection of the input/output systems and AWD CM to determine which part is
malfunctioning.
With the AWD C ...
