System Description: Gauges

Self-diagnostic function 

The gauge control module is equipped with a function to self-diagnose  the internal circuit of the gauge control module.

Speedometer 

The PCM provides a vehicle speed signal to the gauge control module using the F-CAN. Based on this input, the gauge control

module displays the current vehicle speed in the speedometer.

Engine Coolant Temperature 

The PCM provides a engine coolant temperature signal to the gauge control module using the F-CAN. When the engine coolant

temperature is high, the gauge control module displays the warning in the multi-information display.

Ambient Meter 

The ambient meter shows real-time driving information by color on both sides of the gauge control module which promote fuel

efficient driving. When the color is close to green, it means low fuel consumption driving. When the color is close to white, it means

high fuel consumption driving. When SPORT mode is selected, the color changes to red.

Charge/Power Gauge 

Information from the motor control module/battery condition monitor module is received via the F-CAN to indicate the

charge/discharge status of the battery pack.

Fuel Gauge and Fuel Indicator 

The gauge control module displays the fuel gauge based on input value from the fuel gauge sending unit. The low fuel indicator

turn on in the event that indication of the fuel gauge becomes lower than the minimum tank fill threshold.

ODO Meter and Trip Meter 

The PCM provides a vehicle speed signal to the gauge control module via the F-CAN. Based on this input, the gauge control module

tracks mileage for the odometer and trip meters.

Multi-Information Display (MID) 

The multi-information display (MID) provides the average fuel efficiency, instant fuel economy, elapsed time, average speed, and the

status of keyless access system. In addition, the diagnostic system displays the communication errors and the DTCs.

Outside Air Temperature 

The gauge control module uses measurement provided by the outside air temperature sensor signal from climate control unit via the

B-CAN. The outside air temperature indicator's displayed temperature can be recalibrated 5 deg.F ( 3 deg.C)

to meet the customer's expectations.

Gear Position Indicator 

Information from the SBW shifter control module is received via the F-CAN to display the gear position.

Average Fuel Economy Records, Instant Fuel Economy/Average Fuel Economy, Range, Elapsed Time Display, Average Speed Display 

The gauge control module receives signals such as fuel consumption, driving distance, vehicle speed, and engine speed from the

PCM via F-CAN. It calculates average fuel economy records, average/instant fuel economy, elapsed time, average speed, and range.

to display the results.

Gauge Control Module Receives Information 

The gauge control module receives information from each control unit via the F-CAN and the B-CAN to light or flash indicators. The

VSA modulator-control unit, sport mode switch, electric parking brake/automatic brake hold switch, dashlights brightness control

switch, ECON switch, ACC combination switch, VSA OFF switch, CMBS OFF switch, brake fluid level switch, fuel gauge sending unit,

battery charge control module, PCM, audio-navigation unit*1, audio unit*2, washer fluid level switch*3, and HV switch are connect

directly to the gauge control module. The audio remote-HFL switch signal is transmitted to the gauge control module via the LIN

• *1: With navigation
• *2: Without navigation
• *3: With washer fluid level switch

Keyless Access System Information 

The gauge control module receives information from the body control module via the B-CAN to display status of the keyless access system.

Illumination Control 

The illumination brightness can be adjusted using the dashlights brightness control switch.

High Voltage Battery Charge Level Gauge 

The gauge control module displays the remaining high voltage battery charge level.

Buzzer 

The gauge control module includes a buzzer to provide the driver with audible warnings.

Charge Timer Function 

This function enables charging the high voltage battery on schedule by a timer setting. The gauge control module manages the

current time with GPS time via B-CAN and its internal clock. Based on the current time and the scheduled time, the gauge control

module outputs a signal to start charging via F-CAN.

The scheduled time is set in the multi-information display. In the multi-information display, the ON/OFF condition of the charge timer

function and the timer mode can be customized. There are two timer modes, and one is the MODE FULL that starts charging on

schedule and stops charging when full charged and another is MODE TIME that starts and stops charging on schedule. When the

vehicle is turned to the OFF (LOCK) mode, the timer setting condition is displayed in the multi-information display for 6 sec.

In the case that the GPS time is not received for 30 days or more and that the current time is not calculated, the timer charge function

is unavailable.
