Inspection
PISTON AND PISTON PIN CLEARANCE
1. Measure inner diameter of piston pin hole ªdpº.
Standard diameter ªdpº:
20.993 - 20.999 mm (0.8265 - 0.8267 in)
2. Measure outer diameter of piston pin ªDpº.
Standard diameter ªDpº:
20.989 - 21.001 mm (0.8263 - 0.8268 in)
3. Calculate piston pin clearance.
dp þ Dp = þ0.002 to 0.01 mm (þ0.0001 to 0.0004 in)
If it exceeds the above value, replace piston assembly with

Introduction
The Automatic Temperature Control (ATC) system provides automatic regulation of the vehicles interior
temperature. The operator selects ªset temperatureº, on which the regulation is based, regardless of the
outside temperature changes. This is done by utilizing a microcomputer, also referred to as the automatic
amplifier, which receives input signals from several sensors. The automatic amplifier uses these input sig-
nals (including the set temperature) to automatically control the ATC system's outlet air volume, air tem-
perature and air distribution.
Features
Air mix door control
The air mix door is automatically controlled so that in-vehicle temperature will reach, and be maintained at
the operator selected ªset temperatureº. For a given set temperature, the air mix door position will depend
on: Ambient temperature, in-vehicle temperature, amount of sunload, and intake air temperature.
Fan speed control
Blower speed is automatically controlled based on temperature setting, ambient temperature, in-vehicle
temperature, intake air temperature, amount of sunload and air mix door position.
With FAN switch set to ªAUTOº, the blower motor starts to gradually increase air flow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from
flowing.
Intake door control
The intake door position will be determined by: Ambient temperature, in-vehicle temperature, and whether
the compressor is on or off.
Outlet door control
The outlet door position will be determined by: Ambient temperature, in-vehicle temperature, intake air
temperature, and amount of sunload.
Magnet clutch control
The compressor operation (ON-OFF) is automatically controlled by the ambient sensor to prevent compres-
sor damage in very cold ambient temperatures.
Self-diagnostic system
The self-diagnostic system consists of five steps. Each step can be accessed by pushing the switches on
the automatic amplifier.
Memory function
With ignition switch turned OFF, the auto amplifier stores in memory the set temperature and inputs of vari-
ous switches. When the ignition switch is turned ON, the system begins operation with the information stored
in memory. The system, then immediately compensates for the actual operating conditions.

SYSTEM DESCRIPTION
Component parts
Fan speed control system components are:
1) Auto amp.
2) Fan control amp.
3) PBR
4) In-vehicle sensor
5) Ambient sensor
6) Sunload sensor
7) Intake sensor
System operation
Automatic mode
In the automatic mode, the blower motor speed is calculated by the automatic amplifier based on inputs from
the PBR, in-vehicle sensor, sunload sensor, intake sensor and ambient sensor. The blower motor applied
voltage ranges from approximately 5 volts (lowest speed) to 12 volts (highest speed).
The control blower speed (in the range of 5 to 12V), the automatic amplifier supplies a gate voltage to the
fan control amplifier. Based on this voltage, the fan control amplifier controls the voltage supplied to the
blower motor.
Starting fan speed control
Start up from ªCOLD SOAKº condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 50ÉC, the blower will not oper-
ate for a short period of time (up to 150 seconds). The exact start delay time varies depending on the ambi-
ent and engine coolant temperature.
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
55ÉC, at which time the blower speed will increase to the objective speed.
Start up from normal or ªHOT SOAKº condition (Automatic mode)
The blower will begin operation momentarily after the AUTO button is pushed. The blower speed will gradu-
ally rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objec-
tive blower speed).
