SPEEDOMETER : System Description

INFOID:0000000000964331

• 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.

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 and paddle shifter and 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

Refer to 

MWI-53, "Description"

.

Oil pressure switch

Refer to 

MWI-58, "Description"

.

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

Paddle shifter

Transmits the paddle shifter up signal and paddle shifter down signal to the unified meter and A/C 
amp.

TCM

Transmits shift position signal to the unified meter and A/C amp.

Meter control switch

Refer to 

MWI-56, "Description"

.

Washer level switch

Transmits the washer level signal to the combination meter.

Brake fluid level switch

Transmits the brake fluid level switch signal to the combination meter.

Parking brake switch
