Unit
Description
Combination meter
Controls the following with the signals from the unified meter and A/C amp, switches and sensors.
• Speedometer
• Tachometer
• Engine coolant temperature gauge
• Fuel gauge
• Warning lamps
• Indicator lamps
• Information display
• Warning chime
Unified meter and A/C amp.
• The combination meter receives the necessary information from various units via CAN communi-
cation line and transmits them to the unified meter and A/C amp. with the communication line that
connects both of them.
• Transmits the fuel gauge signal from the fuel gauge unit with the communication line that connects
the unified meter and A/C amp. and the combination meter.
• Reads the signals from the A/T device transmits them to TCM with CAN communication line.
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 unified meter and A/C amp. via BCM with CAN communication line.
Fuel level sensor unit
Oil pressure switch
ECM
Transmits the following signals to the unified meter and A/C amp. with CAN communication line.
• Engine speed signal
• Engine coolant temperature signal
• Fuel consumption monitor signal
ABS actuator and electric unit
(control unit)
Transmits the vehicle speed signal to the unified meter and A/C amp. with CAN communication line.
BCM
• Transmits signals provided by various units to the unified meter and A/C amp. with CAN commu-
nication line.
• Transmits the security signal to the combination meter.
A/T device
Transmits the following signals to the unified meter and A/C amp.
• Manual mode signal
• Not manual mode signal
• Manual mode shift up signal
• Manual mode shift down signal
TCM
Transmits shift position signal to the unified meter and A/C amp.
Meter control switch
Trip A/B reset switch
Washer level switch

SPEEDOMETER : System Description
INFOID:0000000003140142
• The ABS actuator and electric unit (control unit) converts the pulse signal provided by the wheel sensor to a
vehicle speed signal and transmits it to the unified meter and A/C amp. with CAN communication line.
• The unified meter and A/C amp. receives the vehicle speed signal from the ABS actuator and electric unit
(control unit) with CAN communication line and transmits it to the combination meter by means of communi-
cation line.
• The combination meter indicates the vehicle speed according to the vehicle speed signal received from the
unified meter and A/C amp. by means of communication line.
