SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
SchematicINFOID:0000000001327660
FunctionsINFOID:0000000001327661
VDC
 In addition to the TCS/ABS function, the driver
steering amount and brake operation amount are detected
from steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under steering /
over steering) is determined from information from G s ensor, wheel sensor, etc., and this information is used
to improve vehicle stability by controlling the braking and engine power to all four wheels.
 SLIP indicator lamp flashes to inform the driver of VDC operation.
 During VDC operation, 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 vehicle is subject
to strong shaking or large vibration, such as when vehi cle is on a turn table, a ship or a steep slope such as
bank while engine is running. In this case, restart engine on a normal road, and if ABS warning lamp, VDC
OFF indicator lamp, and SLIP indicator lamp turn off, there is no malfunction.
TCS
 The wheel spin of the drive wheels is detected by ABS actuator and electric unit (control unit) from the wheel
speed signals from four wheels, so if wheel spin occurs , drive wheel right and left brake fluid pressure con-
trol and engine fuel cut are performed while throttle value is restricted to reduce the engi\
ne torque and
decrease the amount of wheel spin. In addition, the degree throttle is opened is controlled to achieve the
optimum engine torque.
 Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the opti-
mum traction has the highest priority under TCS operation.
 TCS may be activated any time vehicle suddenly accelerates, suddenly down/upshifts, or is driven on a road with a varying surface friction coefficient.
 During TCS operation, it informs a driver of sy stem operation by flashing SLIP indicator lamp.
ABS
 The Anti-Lock Braking System is a function that detec ts wheel revolution while braking, and it improves han-
dling stability during sudden braking by electrically prev enting 4 wheel lock. Maneuverability is also improved
for avoiding obstacles.
 If the electrical system malfunc tions, then the fail-safe function star ts, the ABS becomes inoperative, and
ABS warning lamp turns on.
 Electrical system diagnosis by CONSULT-III is available.
 During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
 When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises may be heard from engine compartment. This is a normal status of operation check.

UNIFIED METER CONTROL UNIT
 Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the comb ination meter. Unified meter control unit receives sig-
nals 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.
 Odo/trip meter, A/T indicator and ICC system disp lay segments can be checked in self-diagnosis mode.
 Meters/gauges can be checked in self-diagnosis mode.
UNIFIED METER AND A/C AMP.
Refer to DI-26, "System Description" in “UNIFIED METER AND A/C AMP”.

 through 10A fuse [No. 19, located in the fuse block (J/B)]
 to combination meter terminal 8, and
 to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied
 through 10A fuse [No. 14, located in the fuse block (J/B)]
 to combination meter terminal 7,
 through 10A fuse [No. 12, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in the fuse block (J/B)]
 to combination meter terminal 4,
 through 15A fuse [No. 10, located in the fuse block (J/B)], and
 through 15A fuse [No. 11, located in the fuse block (J/B)]

 through grounds M35, M45 and M85,
 to unified meter and A/C amp. terminals 29 and 30
 through grounds M35, M45 and M85.
SPEEDOMETER
The speedometer indicates the vehicle speed.
 ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. converts the vehicle s peed signal to the 8-pulse signal, and outputs the vehicle
speed signal (8-pulse) to combination meter.
 Combination meter indicates the vehicle speed according to vehicle speed signal (8-pulse) signal.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
 ECM provides engine speed signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.

COMBINATION METERS
 Combination meter indicates the engine speed according to engine speed signal.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
 ECM provides engine coolant temperature signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with commu-
nication line.
 Combination meter indicates the engine coolant temper ature according to engine coolant temperature sig-
nal.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
 Unified meter and A/C amp. reads a resistor signal from fuel level sensor.
Signal is supplied- from unified meter and A/C amp. terminal 36
- through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
- through the fuel level sensor unit (sub) terminals 2 and 1
- to unified meter and A/C amp. terminal 28 for the fuel gauge.
 Unified meter and A/C amp. provides a fuel level signal to combination meter with communication line.
 Combination meter indicates the approximate fuel level according to the fuel level signal.
ODO/TRIP METER
 ABS actuator and electric unit (control unit) provi des a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.
 Unified meter and A/C amp. converts the vehicle s peed signal to the 8-pulse signal, and outputs the vehicle
speed signal (8-pulse) to combination meter.
 Combination meter uses the vehicle speed signal (8- pulse) to calculate the mileage, and displays it.

 If trip reset switch is pressed for 1 second or more while “trip A” is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-

cable is disconnected.
COMBINATION METER ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter il lumination is turned ON by unified meter control unit.
Nighttime Mode
 Unified meter control unit is transferred to nighttime mode, with ignitio\

 When nighttime mode, illumination c ontrol switch illumination turns
ON by unified meter control unit. Each illumination is controlled by
unified meter control unit.
 Each illumination can be adjusted to 16 step by illumination control switch in nighttime mode.
NOTE:
