Speedometer display function

•  The instrument cluster controls the speedometer based on the vehicle speed signal sent via CAN communication from the PCM, and displays the current vehicle speed. For details on the speedometer, refer to [SPEEDOMETER]. (See SPEEDOMETER.)


Tachometer display function

•  The instrument cluster controls the tachometer based on the engine speed signal sent via CAN communication from the PCM, and displays the current engine speed. For details on the tachometer, refer to [TACHOMETER]. (See TACHOMETER.)


Fuel gauge display function

•  The instrument cluster displays the remaining fuel quantity based on the fuel gauge sender unit voltage signal sent via CAN communication from the rear body control module (RBCM), and the vehicle speed and fuel injection amount signals sent via CAN communication from the PCM. For details on the remaining fuel quantity, refer to [FUEL GAUGE]. (See FUEL GAUGE.)


Odometer/tripmeter display function

•  The instrument cluster displays the total traveled distance/traveled distance over a specific interval based on the travel distance signal sent via CAN communication from the PCM. For details on the odometer/tripmeter, refer to [ODOMETER/TRIPMETER]. (See ODOMETER/TRIPMETER.)


Trip computer calculation function

•  The instrument cluster calculates the instantaneous fuel economy, average fuel economy, and remaining travel distance to empty, and displays the calculated result and the direction of travel on the LCD (without multi-information display)/multi-information display (with multi-information display) in the instrument cluster. For details on the trip computer, refer to [TRIP COMPUTER INFORMATION SYSTEM]. (See TRIP COMPUTER INFORMATION SYSTEM.)


Warning/indicator light turn on/flash function, message/system operation status display function

•  The instrument cluster turns on or flashes the warning indicator lights to notify the driver of the vehicle system status.
•  The types of warning/indicator lights are as follows: For details on each warning/indicator light, refer to each reference.
•  A warning message in the center display is displayed when the warning/indicator light is turned on or flashed. For the display content, refer to [CENTER DISPLAY]. (See CENTER DISPLAY [WITH CENTER DISPLAY].)

Panel Light Control Function

•  The instrument cluster changes the brightness of the panel light based on the panel light control switch rotation signal and TNS (parking lights) signal sent via CAN communication from the front body control module (FBCM). For details on the panel light, refer to [PANEL LIGHT]. (See PANEL LIGHT.)


Vehicle Specification Information Transmission Function

•  The instrument cluster sends vehicle specification information stored during configuration to the following modules via CAN communication.
―  PCM
―  TCM (ATX)
―  AFS control module (with adaptive front lighting system (AFS))
―  Radar unit (with smart brake support (SBS))
―  Forward sensing camera (FSC) (with forward sensing camera (FSC))
―  DSC HU/CM
―  Radar unit (with Mazda Radar Cruise Control (MRCC) system)
―  Electric power steering (EPS) control module
―  Front body control module (FBCM)
―  Rear body control module (RBCM)
―  Start stop unit
―  SAS control module
―  Connectivity master unit (CMU)
―  Audio amplifier (with Bose®)
―  Tuner and amplifier unit (TAU)
―  Electric parking brake control module
―  Occupant classification sensor control module (with two-step deployment control system)
―  Climate control unit
―  Blind spot monitoring (BSM) control module (LH) (with blind spot monitoring (BSM) system)
―  Position memory control module (with position memory system)
―  360°view monitor control module


Battery Discharge Suppression Function

Note
•  This function is for suppressing battery discharge during vehicle manufacture and shipment. However, if the ROOM fuse is removed from a vehicle which has low total travel distance, the function may operate in the market.
•  The battery discharge suppression is a function in which the instrument cluster sends a battery discharge suppression signal to the start stop unit and the start stop unit suppresses the battery discharge.
•  The battery discharge suppression function operates when the total traveled distance is the threshold or less and the ROOM fuse has been removed.
•  The start stop unit switches the ignition off if 25 min have elapsed with the ignition switch in the ACC or ON position (engine off) to control the electric load.
•  When the battery discharge suppression function is operated, the instrument cluster displays [F0-002], [F0-HHH] or [F0-LLL] in the odometer/tripmeter screen of the instrument cluster to indicate that the battery discharge suppression function is operating.
•  The battery discharge suppression function is stopped under the following conditions.
―  ROOM fuse has been installed
―  Engine is started
―  Total traveled distance exceeds the threshold value
