REFRIGERANT RECOVERY, EVACUATING AND CHARGING
OPERATION PROCEDURE FOR REFRIGERANT CHARGING
WARNING:
 Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately
–6°C (32°F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eyes, consult a doctor immediately.
– Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
– Obtain proper treatment as soon as possible from a doctor or eye specialist.
 Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
 Refrigerant must not be handled near where welding or steam cleaning is performed.
 Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
 Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazard-
ous to health.

3B1-4 ELECTRICAL POWER STEERING (P/S) SYSTEM
DIAGNOSIS
The P/S system in this vehicle is controlled by P/S control module. P/S control module has an on-board diagnos-
tic system which detects a malfunction in this system.
When diagnosing troubles, be sure to have full understanding of the outline of “ON-BOARD DIAGNOSTIC SYS-
TEM” and each item in “PRECAUTION IN DIAGNOSING TROUBLE” and execute diagnosis according to “SYS-
TEM CHECK FLOW TABLE”.
ON-BOARD DIAGNOSTIC SYSTEM
P/S control module performs on-board diagnosis (self-diagnosis)
on the system and operates “EPS” warning lamp (1) (malfunction
indicator lamp) as follows.
Malfunction indicator lamp (“EPS” warning lamp) lights when
the ignition switch is turned to ON position (but the engine at
stop) regardless of the condition of P/S control system. This
is only to check the malfunction indicator lamp (“EPS” warn-
ing lamp) bulb and its circuit.
If the areas monitored by P/S control module is free from any
trouble after the engine start (while engine is running), mal-
function indicator lamp (“EPS” warning lamp) turns OFF.
When P/S control module detects a trouble which has
occurred in the areas it monitors, malfunction indicator lamp
(“EPS” warning lamp) turns ON while the engine is running
to warn the driver of such occurrence of trouble and at the
same time it stores the exact trouble area in memory inside
of P/S control module.
PRECAUTIONS IN DIAGNOSING TROUBLES
Take a note of DTC indicated first.
Be sure to read “PRECAUTIONS FOR ELECTRONIC CIRCUIT SERVICE” in Section 0A before inspection
and observe what is written there.
When two or more troubles have occurred, their DTCs are indicated 3 times each starting with the smallest
code number and up.
DTC C1122 (DTC No.22) (engine speed signal failure) is indicated when ignition switch is ON position and
engine is not running but if indication changes to a normal one when engine is started, it means nothing
abnormal.
As DTC is stored in memory of P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC CLEARANCE”.

NOTE:
All front fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and/or could result in major repair expense. They must be replaced with one of same
part number or with an equivalent part if replacement becomes necessary. Do not use a replacement
part of lesser quality or substitute design. Torque values must be used as specified during reassem-
bly to assure proper retention of all parts. There is to be no welding as it may result in extensive dam-
age and weakening of the metal.

5-4 BRAKES
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and reasonably level roadway which is not crowned. Road test
brakes by making brake applications with both light and heavy pedal forces at various speeds to determine if the
vehicle stops evenly and effectively. Also drive vehicle to see if it leads to one side or the other without brake
application. If it does, check the tire pressure, front end alignment and front suspension attachments for loose-
ness. See diagnosis table for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight drop in reservoir level does result from normal lining wear,
an abnormally low level indicates a leak in the system. In such a case, check the entire brake system for leak-
age. If even a slight evidence of leakage is noted, the cause should be corrected or defective parts should be
replaced.
SUBSTANDARD OR CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid may cause the brake fluid to boil or the rubber components
in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the drum brake wheels.
If deterioration of rubber is evident, disassemble all hydraulic parts and wash with alcohol. Dry these parts with
compressed air before assembly to keep alcohol out of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads.
If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed system.
The system must be flushed if there is any doubt as to the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to contaminated fluid.

5-8 BRAKES
BRAKE PEDAL FREE HEIGHT ADJUSTMENT
1) Check brake pedal free height.
If it is not within specification, check and adjust following
item 1) and 2).
Brake pedal free height “a” from dash silencer
LH steering vehicle : 205 – 225 mm (8.08 – 8.85 in.)
RH steering vehicle : 217 – 237 mm (8.55 – 9.33 in.)
2) Check measurement between booster mounting surface and
center of clevis pin hole. When booster push rod clevis has
been reinstalled, it is important that the measurement is
adjusted (refer to BRAKE BOOSTER INSPECTION AND
ADJUSTMENT).
3) Check stop light switch position. Adjust it if it is out of specifi-
cation.
BRAKE PEDAL PLAY INSPECTION
Pedal play should be within specification below. If out of specifi-
cation, check stop light switch for proper installation position and
adjust if necessary.
Also check pedal shaft bolt and master cylinder pin installation for
looseness and replace if defective.
Brake pedal play
“a” : 1 - 8 mm (0.04 - 0.31 in.)
STOP LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when installing switch.
Pull up brake pedal toward you and while holding it there, adjust
switch position so that clearance between end of thread and
brake pedal is as specified. Then adjust stop light switch assem-
bly position and lock it by turning clockwise.
Clearance between brake pedal and stop light switch
“a” : 0.5 - 1.5 mm (0.02 -0.06 in.)

ANTILOCK BRAKE SYSTEM (ABS) 5E-3
The main component parts of this ABS include the following parts in addition to those of the conventional brake
system.
Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–ABS control module which 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 which operates according to signal from ABS control module to control fluid pressure
applied to wheel cylinder of each 4 wheels.
–Fail-safe relay (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and
pump motor relay.
–Pump motor relay which supplies power to pump motor in ABS hydraulic unit.
G sensor which detects body deceleration speed. (For 4WD model only)]
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.
