ET007PRE-POSTHEATING UNIT CONTROL
STATUS DEFINITIONACTIVE: the status is active when the heater plugs are activated according to the
engine coolant temperature.
INACTIVE: the status is inactive after the engine has been running for a certain period.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
Conformity check: Engine running and the engine coolant temperature > 80˚C
ACTIVEWhen the ignition is switched on, status ET007 should be ACTIVE for a time that varies
according to the engine coolant temperature. Both the relay and the heater plugs are
supplied.
After starting the status should remain ACTIVE for a time that varies depending on the
engine coolant temperature. This is postheating.
If ET007 is INACTIVE when the ignition is switched on, check:
–The supply fuse FB1 (70A) of the engine fuse and relay box or F2 (70A) on the power
feed fuse board, according to the vehicle.
–The feed to the heater plugs following relay actuation, and the heater plugs
connections.
–The continuity and the absence of interference resistance between the following
connections:
●Connection code 37Z between components 257 (or 980) and 680.
●Connection code 37AA between components 257 (or 980) and 681.
●Connection code 37AB between components 257 (or 980) and 682.
●Connection code 37AC between components 257 (or 980) and 683.
–That the contacts of the pre-postheating unit connector are in good condition and
connected correctly.
If the vehicle starts, preheating is completed and status ET007 remains ACTIVE during
the engine operating phase, consult the interpretation of faults DF017 Preheating unit
control circuit and DF025 Preheating unit fault finding connection.
INACTIVEIf the vehicle does not start, the status remains INACTIVE and the preheating was not
executed when the ignition was switched on or during the starting phase, check the
following connections:
●connection code 3FY and 3FF between components 120 and 257 (or 980).
Check for + 12 V on the preheating unit.
●Connection code BP35 of component 257 (or 980).
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
