Troubleshooting.
During operation, the air heater may malfunction. A malfunction is identified by the
code displayed on the controller panel, see Table 2 for code descriptions.
Other malfunctions are possible, which are not identified by the control unit. For
instance, loss of tightness of the heat exchanger (burn-out), or burn-out gaskets, or a
decrease in heat output as a result of carbon formation inside heat exchanger. These faults
can be detected visually.
DO NOT USE THE HEAT EXCHANGER IF IT LOSES ITS TIGHTNESS.
During operation of the air heater, failures of individual elements of the heater may
occur, which can be replaced without removing the heater from the vehicle (e.g.:
replacement of the fuel pump; glow plug, controller).
Attention!
In September 2015, a standardization of fault codes was carried out, as a
result some codes were changed.
