Unit

Description

Combination meter

Controls the following with the signals received from each unit via CAN communication and the sig-
nals from switches and sensors. 

• Speedometer

• Tachometer

• Engine coolant temperature gauge

• Fuel gauge

• Engine oil pressure gauge

• Odo/trip meter

• Voltage gauge

• Indicator lamps

• Warning lamps

• Warning chime

• Trip computer

IPDM E/R

IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch 
signal to the combination meter via BCM with CAN communication line.
