activate d within the lower slip ratio
area where
ABS is disab l ed. ABS-ECU calculates
vehicle
decelera t ion a nd slip amou nt of th e four
whe
e ls based on the wheel sp eed senso r signal. If
the rear
wh eel speed dif f ers f r om th e ve hicle speed
by a
cert ain level or more, ABS-ECU boost, holds,
and de
pressurises the rea r wh eel contro l so leno id
valve in the h

e l b r ake fluid pressure fa ir ly close to an ideal dis
-
tribution curve.
INITIAL CHECK
ABS-ECU inter nally activates the self-d iagno stic
function. ABS-ECU illuminates
ABS warning l a mp for
3 seconds (in
c lu ding the in itia l check)
* after th e ign i-
tion switch is turned ON. If a n y malf unction is
detected, ABS-ECU cont
inues illuminating ABS
war
n ing lamp and disables ABS cont rol.
NOTE: *: ABS warning lamp may st ay ON af ter the
ignition
switch is turned ON un til t he st artu p ve hicle
spee
d reaches approximately 10km/h . As far as
ABS-ECU memorizes any d i agn osis code related t o
the
whee l speed sen s or malfunct i on record ed d u ring
previous ignition ON st atus, ABS-ECU continues illu
-
mina ting ABS warn ing lamp until it verif i es that th e
malfunct
i on for tha t co de is resolved (S t a rtup che ck).
STARTUP CHECK
When th e st artup veh i cle sp eed re ache s app roxi-
mately 10 km/h, ABS-ECU performs the following
checks.
•Motor, solen o id valve check (onl y i n ini t ial st ar-
tup*)
Operat es the motor relay in ECU and checks the
pump motor op eratio n. At the same time,
ABS-ECU sequentially e nergizes each solenoid
valve in a ve ry sh ort perio d and ch ecks the valve
ope ration .
NOTE: *: Initia l st artu p ind i ca tes a first st artup af ter
the
system has st arted .
•Whee l speed sensor check
ABS-ECU che cks for a n y whee ls that ha ve no t
received whee l sp eed sens or signal from the
st artu p.
CONSTANT CHECK
ABS-ECU con s t antly ch ecks th e following item.
•ABS-ECU
Performs se lf-diagnosis in ECU.
•ECU power supply
Checks if ECU po we r sup p ly volt ag e reaches within
the operat ional range .
•Whee l speed sensor
•Monitors the ou tput volt age of the sensor sig-
nal wiring ha rness an d che c ks for a bnormal
output
volt ag e (ope n/sho r t circuit).
•Checks fo r any wheels tha t do n o t send pu lse
sig
nal while th e ve hicle is in motion.
•Checks if wheel spee d which is abno rmally
high
er or lo we r than the vehicle speed is
inpu
t.
•Pump mo tor and solenoid valve
Checks tha t ABS-ECU outp u t signal and t he ope rat-
ing co ndition of the pump motor an d so leno id
valve agree
with ea ch ot her .

NOTE: .
•*: If any trouble occurs in CAN communication,
the brake warning lamp and ABS warning lamp
on the combination meter turns ON.
•Prohibit: Any controls are not performed until the
ignition switch is turned OFF.
•System shut-down: Control will be disabled until
valve power supply is turned off, and then ignition
switch is turned to the OFF position.
•Wait: ABS control is restarted when the normal
condition is resumed even though the ignition
switch is not turned OFF.
DIAGNOSTIC FUNCTION
ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using the M.U.T.-III (ABS warning lamp illuminates
and ABS control is prohibited while the ABS-ECU
communicates with the M.U.T.-III).
•Diagnosis code set
•Service data output
•Actuator test
DIAGNOSIS CODE SET
There are 28 diagnostic items. Since all the diagnos-
tic results are recorded in volatile memory (EEP-
ROM*), they are stored in the memory even though
the battery terminals are disconnected.
NOTE: .
•*EEPROM (Electrical Erasable &;Programmable
ROM): Special type of memory that can be pro
-
grammed or erased electrically
•For each diagnostic item, refer to Fail-safe Func-
tion.

DOOR MIRROR
M2510008100154
The door mirror is a folded type and has the following
characteristics.
•Features an electric retractable remote controlled
mirror.
•Vehicle speed-dependent automatic return func-
tion.
•A vertically-enlarged mirror has been used for
easy confirmation of safety around the vehicle.
•Aerodynamic door mirror shape have been devel-
oped so that the door glasses and mirrors do not
easily get wet with raindrops while driving in a
rainy day.
•Flag type door mirror shape which secures suffi-
cient distance between the door mirror and delta
pillar has been adopted to reduce the blind spot
area of the forward view.
