VI - Pre-postheating actuation
Pre/postheating control involves actuating the heater plugs and the preheating indicator light on the instrument
panel (multiplex signal).
The heater plugs are actuated by a static relay.
After the ignition is switched on, a preheating delay is activated. The length of time that the warning light is lit
depends on the coolant temperature, air temperature, atmospheric pressure and battery voltage. When the coolant
temperature is below a certain threshold, a postheating function can be used to improve the combustion stability,
and consequently engine operation (reducing unburnt particles and pollutant emissions). Postheating can last up
to5 minutes.
IMPORTANT:
There are two types of heater plug: SLOW and FAST:
SLOW plugs are identified by a black ring.
FAST plugs are identified by a white ring.
The heater plugs fitted on the vehicle must be replaced with plugs of the same type; otherwise there is
a risk of the heater plugs deteriorating which could lead to engine destruction.
Only Vdiag 20, 24, 38 and 74:
when replacing heater plugs with plugs which differ from those currently fitted on the vehicle (replacement of
SLOW plugs with FAST plugs), the computer must be configured (see Replacement of components, Replacing
heater plugs) by running command SC036 Reinitialise programming and selecting Heater plugs if this choice
is available, then following the procedure.

In Vdiag 18, 1C, 54:
Each of these parameters contains the vehicle mileage during a failed particle filter regeneration when driving.
Each parameter relates to an engine status. The statuses and parameters are recorded at the same time (for
example PR797 is associated with ET709 Stored engine status no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero and there is a regeneration failure when driving, the distance
information for PR794 is cleared and replaced by the new value.
For other Vdiags:
Every parameter between PR794 Stored regeneration failure no. 1 and PR803 Stored regeneration failure no.
10 contains the vehicle mileage at the time of a particle filter regeneration failure when driving. Each parameter
relates to an engine status. They are recorded simultaneously (for example PR797 is associated with ET709
Stored engine status no. 4).
PR794 to PR803 operate through successive copying (when there is a regeneration failure when driving, the value
of PR794 is copied to PR795 Stored regeneration failure no. 2, the value of PR795 is copied to PR796 Stored
regeneration failure no. 3 and so on).
When there are more than ten records, the value of PR803 is deleted. The new mileage is allocated to PR794.
