(upper).
+Align the dowel pin at the lower position of cylinder block with
the hole on the gear case side.
+Tap the area around the dowel pin with a plastic hammer if it
cannot be inserted easily.

Self-diagnosis
INTRODUCTION AND GENERAL DESCRIPTION
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. by system line.
Self-diagnosis is step-1 to 7. There are two ways of changing method during self-diagnosis.
+Switching to self-diagnosis step-1 to 4.
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing A/C switch for at least 5 seconds. The A/C switch must
be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system will be
canceled by either pressing intake switch or turning the ignition switch OFF. Shifting from one step to
another is accomplished be means of turning fan control dial, as required.
+Switching to self-diagnosis step-5 to 7 (Auxiliary mechanism).
Shifting from usual control to the self-diagnostic system is accomplished by starting the engine (turning
the ignition switch from OFF to ON) and pressing intake switch for at least 5 seconds. The intake switch
must be pressed within 10 seconds after starting the engine (ignition switch is turned ON). This system
will be canceled by either pressing A/C switch or turning the ignition switch OFF. Shifting from one step
to another is accomplished by means of turning fan control dial, as required.

AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of  3ÉC between temperature setting (Temperature control
dial position) and temperature felt by driver.
Operating procedures for this trimmer are as follows:
1. Set temperature at 25ÉC.
2. Set fan control dial to OFF.
3. Turn ignition switch ON.
4. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
5. Turn temperature control dial as desired. Temperature will change at a rate of 1ÉC each time a dial is
turned.

When battery cable is disconnected, trimmer operation is canceled. Temperature set becomes that of initial
condition, i.e. 0ÉC.
AUXILIARY MECHANISM: FOOT POSITION SETTING TRIMMER
CAUTION:
This A/C system cannot perform the setup of the FOOT position.
LED of A/C switch illuminates. It means that it is ®xed to the initial setting.
AUXILIARY MECHANISM: INLET PORT MEMORY FUNCTION
When ignition switch is turned from OFF to ON, inlet port can be set to AUTO or manual.
Operating procedures for this trimmer are as follows:
1. Set fan control dial to 1st - 25th step.
2. Turn ignition switch ON.
3. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
