Components and Functions
Component Function
4WD switch When the transfer shift lever is shifted to 4L or 4H position from 2H, this switch
turns ON and cause the 4WD control system to turn ON.
4WD controller When the 4WD switch turns on, the 4WD controller activates VSV2 to lock the
air locking hubs and when it receives an “ON” signal from the vacuum switch, it
makes VSV2 to complete operation within 5 seconds and causes the 4WD indi-
cator light to light up.
If vacuum in the vacuum circuit fails to reach the specified level due to a leakage
in the vacuum circuit (when no “ON” signal is inputted from the vacuum switch),
the 4WD controller stops operation of VSV2 in 15 seconds and makes the 4WD
indicator light to flash to warn occurrence of a trouble.
When the 4WD switch turns off, the 4WD controller activates VSV1 for 10 sec-
onds to unlock the hubs and at the same time makes the 4WD indicator light
turn off.
VSV1 VSV1 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to unlock to the slide gear in the air locking hub. As a result, the
air locking hubs are unlocked.
VSV2 VSV2 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to lock to the slide gear in the air locking hub. As a result, the air
locking hubs are locked.
Vacuum switch When VSV2 receives the “ON” signal from 4WD switch, vacuum is applied
through its circuit to the vacuum switch. The vacuum switch turns on when it
detects vacuum exceeding 260 mmHg.
“4WD” indicator lamp It lights up when 4WD control system is in the 4WD mode.
It flashes to warn that locking hub operation has not completed (4WD control
system fails to shift 4WD).

Rear Drum Brake Shoe Adjustment
Rear brake has self-adjusting mechanism but it does require
adjustment for proper drum to shoe clearance when brake shoe
has been replaced or brake drum has been removed for some
other service.
Adjustment is automatically accomplished by depressing brake
pedal about 30 times with approximately 30 kg (66 Ibs) load after
all parts are installed.
Then check brake drum for dragging and brake system for proper
performance. After lowering vehicle from hoist, brake test should
be performed.
Parking Brake Inspection and Adjustment
INSPECTION
Hold center of parking brake lever grip and pull it up with 20 kg
(44 Ibs) force.
With parking brake lever pulled up as above, count ratchet
notches.
There should be 6 to 8 notches.
Also, check if both right and left rear wheels are locked firmly. To
count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its but-
ton.
One click sound corresponds to one notch.NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.

General Description
The ABS (Antilock Brake System) is a system to prevent each wheel to lock during hard braking or braking on a
slippery road by controlling the fluid pressure from master cylinder to each brake (either brake caliper or wheel
cylinder).
The ABS of this vehicle monitors all four wheels (four sensors) and controls all four wheels when the system is
active.
The component parts of this ABS includes following parts in addition to those of the conventional brake system.
Wheel speed sensor senses revolution speed of each wheel and sends outputs to ABS control module.
In this ABS, ABS hydraulic unit (actuator assembly), ABS control module, pump motor transistor and fail-
safe transistor are combined as one component.
ABS control module sends operation signal to ABS hydraulic unit to control fluid pressure applied to each
wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.
ABS hydraulic unit operates according to signal from ABS control module and controls fluid pressure applied
to wheel cylinder of each of 4 wheels.
Fail-safe transistor which supplies power to solenoid valve in ABS hydraulic unit.
Pump motor transistor supplies power to pump motor in ABS hydraulic unit.
“ABS” warning lamp lights to inform abnormality when system fails to operate properly.
G sensor which detects body deceleration speed.

ABS Control Module
Self-diagnosis function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time
and indicates the results (warning of abnormality occurrence and
DTC) through the “ABS” warning lamp as described below.
1) When ignition switch is turned ON, “ABS” warning lights for 2
seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in
good condition), “ABS” warning lamp turns OFF after 2 sec-
onds.
3) When an abnormality in the system is detected, “ABS” warn-
ing lamp lights and the area where that abnormality lies is
stored in the memory in ABS control module.
4) When Diag. switch terminal of monitor connector is
grounded, the abnormal area is output as DTC.
For procedure to clear all DTC’s, refer to the item “Diagnostic
Trouble Code (DTC) Clearance” in this section.
Fail-safe function
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe transistor which sup-
plies power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without
ABS.SYSTEM CONDITIONDIAGNOSIS

DRIVING CYCLE
A “Driving Cycle” consists of engine startup and engine shutoff.
2 DRIVING CYCLES DETECTION LOGIC
The malfunction detected in the first driving cycle is stored in
ECM memory (in the form of pending DTC and freeze frame data)
but the malfunction indicator lamp does not light at this time. It
lights up at the second detection of same malfunction also in the
next driving cycle.
PENDING DTC
Pending DTC means a DTC detected and stored temporarily at 1
driving cycle of the DTC which is detected in the 2 driving cycle
detection logic.
FREEZE FRAME DATA
ECM stores the engine and driving conditions (in the from of data
as shown in the figure) at the moment of the detection of a mal-
function in its memory. This data is called “Freeze frame data”.
Therefore, it is possible to know engine and driving conditions
(e.g., whether the engine was warm or not, where the vehicle was
running or stopped, where air / fuel mixture was lean or rich)
when a malfunction was detected by checking the freeze frame
data. Also, ECM has a function to store each freeze frame data
for three different malfunctions in the order as the malfunction is
detected. Utilizing this function, it is possible to know the order of
malfunctions that have been detected. Its use is helpful when
rechecking or diagnosing a trouble.
Priority of freeze frame data :
ECM has 4 frames where the freeze frame data can be stored.
The first frame stores the freeze frame data of the malfunction
which was detected first. However, the freeze frame data stored
in this frame is updated according to the priority described below.
(If malfunction as described in the upper square “1” below is
detected while the freeze frame data in the lower square “2” has
been stored, the freeze frame data “2” will be updated by the
freeze frame data “1”.)
[A] : An Example of Freeze Frame Data
[B] : 1st, 2nd or 3rd in parentheses here represents which position in the order
the malfunction is detected.
PRIORITY FREEZE FRAME DATA IN FRAME 1
1Freeze frame data at initial detection of mal-
function among misfire detected (P0300 –
P0304), fuel system too lean (P0171) and fuel
system too rich (P0172)
2Freeze frame data when a malfunction other
than those in “1” above is detected

On-Board Diagnostic System (Vehicle without
Immobilizer Indicator Lamp)
ECM diagnosis troubles which may occur in the area including
the following parts when the ignition switch is ON and the engine
is running, and indicates the result by turning on or flashing mal-
function indicator lamp (1).
Heated oxygen sensor (if equipped)
ECT sensor
TP sensor
IAT sensor
MAP sensor
CMP sensor
CKP sensor
Knock sensor
VSS
CPU (Central Processing Unit) of ECM
ECM and malfunction indicator lamp (1) operate as follows.
Malfunction indicator lamp (1) lights when the ignition switch
is turned ON (but the engine at stop) with the diagnosis
switch terminal ungrounded regardless of the condition of
Engine and Emission Control system. This is only to check
the malfunction indicator lamp (1) bulb and its circuit.
If the above areas of Engine and Emission Control system is
free from any trouble after the engine start (while engine is
running), malfunction indicator lamp (1) turns OFF.
When ECM detects a trouble which has occurred in the
above areas, it makes malfunction indicator lamp (1) turn ON
while the engine is running to warn the driver of such occur-
rence of trouble and at the same time it stores the trouble
area in ECM back-up memory. (The memory is kept as it is
even if the trouble was only temporary and disappeared
immediately. And it is not erased unless the power to ECM is
shut off for specified time below.)
ECM also indicates trouble area in memory by means of
flashing of malfunction indicator lamp (1) at the time of
inspection. (i.e. when connecting diagnosis switch terminal
(2) and ground terminal (4) of monitor connector (3) with a
service wire (5) and ignition switch is turned ON.)
NOTE:
When a trouble occurs in the above areas and disap-
pears soon while the diagnosis switch terminal is
ungrounded and the engine is running, malfunction
indicator lamp (1) lights and remains ON as long as the
trouble exists but it turns OFF when the normal condi-
tion is restored.
Time required to erase diagnostic trouble code mem-
ory thoroughly varies depending on ambient tempera-
ture as follows.
