5 Series E60 530d (M57T2) SAL
•
Sufficient fuel in the vehicles tank for a range of at least 50 km
•
On-board supply voltage OK
The independent heater has the following functions:
•
Auxiliary heating with running engine (pseudo auxiliary heating)
•
Telestart (via CAS)
•
LoW-voltage cutout
Auxiliary heating with running engine (pseudo auxiliary heating)
When the independent heater is running, pseudo auxiliary heating mode is started when the engine is started.
When pseudo auxiliary heating mode is activated, the independent heater indicator lamp goes out.
If the engine temperature is greater than or equal to the temperature of the independent heating circuit, the
system will change from pseudo auxiliary heating mode to auxiliary heating. These two modes differ in that only
the independent heater circuit is used in pseudo auxiliary heating mode, while in auxiliary heating mode the
larger heater circuit is used.
Telestart (via CAS)
The average range of the Telestart transmitter is approx. 150 meters. The CAS forwards the signal from the
Telestart transmitter through the body CAN to the following control units:
-
IHKA control unit
-
Independent heater control unit
LoW-voltage cutout (via DME/DDE)
The battery's charge level is constantly monitored by the intelligent battery sensor throughout the independent
heating operation. If the necessary charge level is not maintained, the IHKA control unit will deactivate the
independent heating operation.
