5. Troubleshooting
5.1. General
a) A systematic approach is advisable for troubleshooting.
Appropriate action must be undertaken as described below for
faults of a general nature or when normal conditions are not
obtained during the pressure test.
b) Certain faults can only be located and remedied by skilled
personnel using special tools.
5.2. Cause of faults in the electrical system
The individual circuits must be systematically checked with the aid
of the circuit diagram (see para. 4.2) and the fault localized. Above
all plug connections, switches, relays, etc., should be checked for
continuity. The following possibilities must always be checked and
excluded as a possible cause of the malfunction:
−
Defective fuses
−
Corrosion of plug contacts
−
Loose contact in plug connectors
−
Wrong crimping on connector
−
Corrosion on wiring and fuses
−
Corrosion on battery poles
5.3. Cause of faults in the air-conditioning system
−
defective condenser fan
−
soiled condenser fins
−
shortage of refrigerant in the system
−
check front box also
If the system is deactivated continuously, we recommend that it be
checked by an authorized workshop.
5.4. Dealing with problems in the refrigerant circuit
If faults develop in the refrigerant circuit, the system must be tested
and repaired by an authorized specialist repair shop according to
the rules. Refrigerant must never be discharged into the
atmosphere.
