STATUS
DEFINITIONACTIVE: These statuses indicate that the thermoplungers are active.
INACTIVE: These statuses indicate that the thermoplungers are inactive.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"INACTIVE"Statuses ET024, ET025, and ET026 are INACTIVE when the ignition is switched on
with the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET024, ET025, and ET026 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°C),
– and the air temperature is low (< 5°C).
This strategy allows the engine coolant to be heated and to allow the heating of the
passenger compartment.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no. 1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no. 3 relay.
In the event of a fault, refer to the interpretation of faults:
– DF032 Thermoplunger no. 1 relay control circuit,
– DF033 Thermoplunger no. 2 relay control circuit,
– DF034 Thermoplunger no. 3 relay control circuit.

STATUS
DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.

NOTESNone.
"INACTIVE"Statuses ET205, ET206, ET207 are INACTIVE when the ignition is switched on
and the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET205, ET206 and ET207 are ACTIVE when the engine is started, the
engine coolant temperature is low (<15°C) and the air temperature is low (<5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
The thermoplungers also act both to load the engine to improve regeneration of
the particle filter.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no.1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no.3 relay.
In the event of a fault, refer to the interpretation of faults:
