GENERAL DESCRIPTION
NEW AIR CONDITIONING SYSTEM WITH
HFC134a
Refrigerant CFC 12 (R 12), previously used in automobiles'
air conditioning systems is believed to contribute towards the
depletion the earth's ozone layer. The ozone layer help to
protect us against the harmful ultraviolet rays of the sun.
A newly developed refrigerant, HFC 134a (R 134 a), does not
the destroy the ozone layer.
PRECAUTIONS FOR SERVICING
HFC134a AIR CONDITIONINGS
1. USE OF NEW REFRIGERANT HFC134a
The very different characteristics of refrigerants HFC134a
and CFC12 have determined the design of their respective
air conditioning systems. Under no circumstances allow
CFC12 to enter an HFC134a system, or vice versa, because
serious damage could occur.
2. USE OF PROPER COMPRESSOR OIL
Compressor oil used in conventional CFC12 air conditioning
systems cannot be used in HFC134a air conditioning sys-
tems.
Always use genuine Toyota R134a air conditioning oil ND±
OIL 8, made expressly for use with HFC134a.
NOTICE: Compressor oil (ND±OIL 8) for HFC134a use ad-
versely affects acrylic resin, so take care not to spill or
spray any compressor oil.
If even a small amount of the wrong oil is changed, it will result
in clouding of the refrigerant.
A large amount will cause the compressor to seize up. AC±2

3. HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of the oil pump, the valve body, the solenoid valves, the accu-
mulators, the clutches and brakes, as well as the fluid passages which connect all of these components.
Based on the hydraulic pressure created by the oil pump, the hydraulic control system governs the hy-
draulic pressure acting on the torque converter clutch, clutches and brakes in accordance with the ve-
hicle driving conditions.
There are 5 solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to control the shift
valves, and change the gear shift position.
The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lock-up
clutch of the torque converter clutch.
The No.4 solenoid valve is operated by signals from the ECM to control the engagement speed and
reduce gear shift shock.
The No.5 solenoid valve is operated by signals from the ECM to regulate the line pressure to throttle
pressure.

3. HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of the oil pump, the valve body, the solenoid valves, and the
clutches and brakes, as well as the fluid passages which connect all of these components. Based on
the hydraulic pressure created by the oil pump, the hydraulic control system governs the hydraulic pres-
sure acting on the torque converter clutch, clutches and brakes in accordance with the vehicle driving
conditions.
There are 3 solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to operate the shift
valves and change the gear shift position.
The lock-up solenoid valve is operated by signals from the ECM to engage or disengage the lock-up
clutch of the torque converter clutch.

LINE PRESSURE
Line pressure is the most basic and important pressure used in the automatic transmission, because
it is used to operate all of the clutches and brakes in the transmission.
If the primary regulator valve does not operate correctly, line pressure will be either too high or too low.
Line pressure that is too high will lead to shifting shock and consequent engine power loss due to the
greater effort required of the oil pump; line pressure that is too low will cause slippage of clutches and
brakes, which will, in extreme cases, prevent the vehicle from moving. Therefore, if either of these prob-
lems are noted, the line pressure should be measured to see if it is within specification.

THROTTLE PRESSURE
Throttle pressure is always kept in accordance with the opening angle of the engine throttle valve. This
throttle pressure acts on the primary regulator valve and, the line pressure is regulated according to
the throttle valve opening.
In the hydraulically controlled automatic transmission, throttle pressure is used for regulating line pres-
sure and as signal pressure for up-shift and down-shift of the transmission. In the electronically con-
trolled transmission, however, throttle pressure is used only for regulating line pressure. Consequently,
improper adjustment of the transmission throttle cable may result in a line pressure that is too high or
too low. This, in turn, will lead to shifting shock or clutch and brake slippage.

HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of an oil pump, valve body, solenoid valves, accumulators,
clutches and brakes, as well as the fluid passages which connect all of these components. Based on the
hydraulic pressure created by the oil pump, the hydraulic control system governs the hydraulic pressure
acting on the torque converter clutch, clutches and brakes in accordance with the vehicle driving condi-
tions.
There are five solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to control the shift valves,
and change the gear shift position.
The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lock±up clutch
of the torque converter clutch.
The No.4 solenoid valve is operated by signals from the ECM to control the engagement speed and reduce
gear shift shock.
The No.5 solenoid valve is operated by signals from the ECM to regulate the line pressure to throttle pres-
sure.

NOTICE: When replacing worn pads, the anti±squeal
shims must be replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or equivalent.
HINT:
wAlways change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.
wIf the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid
escape.
(c) Install the anti±squeal shim on each pad.
HINT:
wPlace the pad wear indicator facing downward.
wApply disc brake grease to inner side of the antisqueal.
wMake sure that the arrow on the shims points upward.
