SYSTEM DESCRIPTIONPFP:00000
System DiagramEFS005TJ
FunctionsEFS005TK
ABS
lThe Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheels lock. Maneuverability is also
improved for avoiding obstacles.
lElectrical system diagnosis by CONSULT-II is available.
EBD
lElectronic Brake Distributor is a function that detects subtle slippages between the front and rear tyre dur-
ing braking, and it improves handling stability by electrically controlling the brake fluid pressure which
results in reduced rear tyre slippage.
lElectrical system diagnosis by CONSULT-II is available.
Operation That Is Not “System Error”EFS005TL
ABS
lWhen starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating noise
may be heard from engine room. This is a normal states of the operation check.
lDuring ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionEFS005TM
ABS, EBD SYSTEM
In case of electrical malfunction with ABS, ABS warning lamp will turn on. In case of electrical incidents with
EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of following
conditions of Fail-Safe function.
1. For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
ABS system.
NOTE:
ABS self-diagnosis sound may be heard.That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
2. For EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.

Symptom 4: ABS Function Does Not OperateEFS005UB
CAUTION:
ABS does not operate when speed is 10 km/h (6 MPH) or lower.
1.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
OK or NG
OK >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR” of symptom1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
NG >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
Symptom 5: Pedal Vibration or ABS Operation Sound OccursEFS005UC
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
lWhen shifting gears
lWhen driving on slippery road
lDuring cornering at high speed
lWhen passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
lWhen pulling away just after starting engine [at approximately 10 km/h (6 MPH) or more]
1.SYMPTOM CHECK 1
Check if there is pedal vibration or operation noise when the engine is started.
Do symptoms occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
2.SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO procedure 3²CHECK WHEEL SENSOR AND SENSOR ROTOR²of symptom 1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
Symptom 6: ABS Warning Lamp Indication Is Not NormalEFS005UD
NOTE:
Lighting condition of ABS warning lamp refer toBRC-24, "
BASIC INSPECTION 3 ABS WARNING LAMP AND
BRAKE WARNING LAMP INSPECTION".
1.CHECK COMBINATION METER INDICATION
Check the combination meter indication and operation. Refer toDI-13, "
Self-Diagnosis Mode of Combination
Meter".
OK or NG
OK >> GO TO 2.
NG >> Combination meter is malfunctioning. Check combination meter. Refer toDI-4, "

ENGINE OIL MAINTENANCE INFORMATION
lEngine oil maintenance information displays maintenance intervals of engine oil.
lWith ignition switch ON position, engine oil maintenance information is displayed on odo/trip meter display
for 5 seconds.
NOTE:
Refer to Owner's Manual for setting.
METER ILLUMINATION CONTROL
When the lighting switch is turned ON, the odo/trip meter switch (1)
can be used to adjust the brightness of the combination meter illumi-
nation.
CLOCK
With ignition switch ON position, combination meter displays clock
on clock display. Time can be adjusted by clock switch (1). Clock can
be adjusted to 12-hour or 24-hour cycle clock.
NOTE:
If the battery cable is disconnected, the clock displays the time 12:00
in 12-hour mode.
AMBIENT AIR TEMPERATURE INDICATION
Combination meter displays ambient air temperature on clock display.
With ignition switch ON, “°C” blinks for a while. Ambient air temperature indication can be selected between
Centigrade and Fahrenheit.
Combination meter reads ambient air temperature signal from ambient sensor.
Signal is supplied
lfrom combination meter terminal 49
lthrough ambient sensor terminals 1 and 2
lto combination meter terminal 50.
When a temperature detected by sensor rises, combination meter controls increase of the indicated tempera-
ture depending on engine heat and other effective factors.
lIf the vehicle speed is more than 20 km/h, the indicated temperature rises according to the vehicle speed.
lIf the vehicle speed is less than 20 km/h, the indicated temperature is maintained.
When a temperature detected by sensor falls, the temperature is indicated immediately.
NOTE:
The range indicated on the display is between-30 and 60°C for Centigrade or between-22 and 99°Ffor
Fahrenheit.
lWhen the temperature is from-40°C(-40°F) to-30°C(-22°F), “--°C” is indicated on the display as
over range.
lWhen the temperature is under-40°C(-40°F) or over 60°C(140°F), nothing is indicated.
lWhen indicated temperature becomes less than 3°C(37°F), ambient air temperature indication blinks
warning. After blinking for 20 seconds, only “°C” blinks. At more than 4°C(39°F) the display stops blink-
ing.

WARNING CHIMEPFP:24814
System DescriptionEKS00L9D
lBuzzer for warning chime system is installed in the combination meter.
lThe buzzer sounds at the following conditions:
–When combination meter receives buzzer output signal with CAN communication line
–When combination meter judges warning chime sound condition is found
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 50A fusible link (letterG, located in the fuse and fusible link box)
lto BCM terminal 57.
With ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No. 1, located in the fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver's door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.
lBCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to combination
meter with CAN communication line.
lWhen combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer toBCS-3, "
COMBINATION SWITCH READING FUNCTION".
KEY REMINDER WARNING CHIME
Key reminder chime sounds, at the same time, when key reminder system starts operating.
key reminder chime also sounds when the following three conditions are simultaneously met.
lKey is inserted in the ignition key cylinder
lDriver¢s door is opened
lThe setting of driver¢s door lock knob is “LOCK”
For information regarding key reminder system, refer toBL-21, "
POWER DOOR LOCK SYSTEM".
LOW-FUEL WARNING CHIME
Low-fuel warning chime sounds, when low-fuel warning lamp is turned ON.
Combination meter sounds warning chime three times when low-fuel warning lamp turns ON.
