SYSTEM DESCRIPTIONPFP:00000

FunctionsBFS000DQ
VDC

In addition to the TCS/ABS function, the steering amount and brake operation amount are detected from
the steering angle sensor and brake switch, and the driving condition (amount of under-steering/over-
steering) is determined from information from the yaw rate/side/decel G sensor, vehicle speed sensor, etc.
This information is used to improve vehicle stability by controlling the braking and engine power to all four
wheels.

The SLIP indicator lamp flashes to inform the driver of VDC operation.

During VDC operation, the body and brake pedal lightly vibrate and mechanical noises may be heard.
This is normal.

ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while
engine is running. In this case, restart engine on a normal road, and if ABS warning lamp, VDC OFF indi-
cator lamp, and SLIP indicator lamp turn off, there is no malfunction.
TCS

Speed signals for 4 wheels control engine output and transaxle conditions so that slip rate of the drive
wheels is optimum. ABS actuator and electric unit (control unit) detects wheelspin. Output from the control
unit controls brake fluid pressure to both LH and RH drive wheels while cutting fuel to the engine and clos-
ing the throttle valve to reduce engine torque when wheelspin is detected. Throttle position is continuously
controlled to ensure the appropriate engine torque at all times.

Depending on road conditions, the driver may have a sluggish feel. This is normal, because the optimum
traction has the highest priority by TCS operation.

TCS may be activated momentarily the vehicle suddenly accelerates, suddenly downshifts, or is driven on
a road with a varying surface friction coefficient.

During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.

System DescriptionBKS001RX
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter. Unified meter control unit receives signals from unified meter
and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter and shift indicator segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination control

Unified meter control unit produces an illumination output of the
combination meter when the ignition switch is “ON”.

Light levels can be adjusted by pressing illumination control
switch of the combination meter when lighting switch is “ON”.

Illumination control switch has five light level settings.
NOTE:
When it is light outside, light level cannot be adjusted by turning
on the lighting switch.
UNIFIED METER AND A/C AMP.
Refer to DI-27, "System Description" in “UNIFIED METER AND A/C AMP”.

UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated in the A/C auto
amp.

Unified meter and A/C amp. controls each operation for A/C
auto amp. For information regarding A/C control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .

Unified meter and A/C amp. inputs necessary information for
combination meter from each unit by CAN communication and
so on.

And unified meter and A/C amp. outputs these signals using
communication line (TX, RX) between unified meter and A/C
amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (with display unit) using CAN communication.

Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).
