HEATER, AIR CONDITIONING AND VENTILATION55-146
Sharper bends will reduce the flow of refrigerant. The flexible
hose lines should be routed so that they are at least 80 mm
(3.1 inches) from the exhaust manifold. It is good practice to
inspect all flexible hose lines at least once a year to make sure
they are in good condition and properly routed.
On standard plumbing fittings with O-rings, these O-rings are
not reusable.
AIR CONDITIONING NOISE TEST
You must first know the conditions when the noise occurs.
These conditions are: weather, vehicle speed, in gear or neu-
tral, engine temperature or any other special conditions.
Noises that develop during A/C operation can often be mislead-
ing. For example: what sounds like a failed front bearing or
connecting rod, may be caused by loose bolts, nuts, mounting
brackets, or a loose clutch assembly. Verify accessory drive
belt tension (power steering or generator).
Improper accessory drive belt tension can cause a misleading
noise when the compressor is engaged and little or no noise
when the compressor is disengaged.
Drive belts are speed-sensitive. That is, at different engine
speeds, and depending upon belt tension, belts can develop
unusual noises that are often mistaken for mechanical prob-
lems within the compressor.
Normal air conditioning operation will generate some level of
operational noise. To judge what is normal and abnormal,
requires an understanding of the air conditioning system. This
test is to detail the most common noise complaints and the
repair methods.
VEHICLE CONDITION
1. Ensure the system is not over or under charged.(Refer to
P.55-142).
2. Tighten all compressor mounting bolts, clutch mounting
bolts and compressor drive belt.
3. Inspect layout of the system is correct, ie no interference
between hoses and all retaining clamps are in place.

HOW TO REGISTER SECRET CODEBGBHCCCB
Required Special Tools:
: MUT-III Sub Assembly
MB991824: Vehicle Communication Interface (V.C.I.)
MB991910: MUT-III Main harness A
Each individual secret code is registered inside the transmitter,
and so it is necessary to resister these codes with the
EEPROM inside the receiver in the following cases.
When the transmitter or ETACS-ECU is replaced
If more transmitters are to be used
If it appears that a problem is occurring because of faulty
registration of a code.
A maximum of four different codes can be stored in the
EEPROM memory (four different transmitters can be used).
When the code for the first transmitter is registered, the previ-
ously registered codes for all transmitters are cleared. There-
fore, if you are using four transmitters or are adding more
transmitters, the codes for all transmitters must be registered at
the same time.
WHEN SPECIAL TOOL MB991824 (V.C.I.) IS USED
.
1. Check that the doors lock normally when the key is used.
2. Insert the ignition key.
