Repair request with DF312 Speed request present or stored ONLY
Read the information from theParticle filter history sub-function: PR784 to PR793 Stored DF312 No. 1 to No. 10
Are PR784 to PR793 all equal to 0 miles (0 km)?
Among these parameters (PR784 to PR793):
– Find the parameter with the highest mileage: it is the Mileage of the last DF312.
– Note the parameter index on the order of repair with the relevant mileage value.
E.g.: PR787 = 2794 miles (4657 Km).
Read the information in the Particle filter history sub-function:
PR794 to PR803 Stored regeneration failures No. 1 to No. 10.
Is at least one of parameters PR794 to PR803 = 19660 miles
(32766 km)?
Identify the distance(s) from the values of parameters PR794 to PR803 Stored regeneration failures No.
1 to No. 10 included between the Distance of the last DF312 and the Distance of the last DF312 - 120
miles (- 200 km). This is the Distance of the most recent failures.

PART B
1. No particle filter regeneration.
2.Write on the repair order the parameter and status relating to the last failure:
– Mileage of the last DF312 Speed request.
– Mileage of the last failures.
– Engine statuses of the last failures.
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3. Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the particle filter warning light or message came on (appeared at the Mileage of the last
DF312), the customer had not respected the driving recommendations: the failure that occurred at the Mileage of
the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PART D.
PART C
If Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
If Vdiag 1C, 54, 58, 20 and 24:
– Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
– Carry out an After-Sales regeneration with approval from the Techline.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
In Vdiag 18, 1C, 54:
Each parameter from PR784 to PR793 records the distance when the particle filter warning light comes on which
is associated with the appearance of DF312.
Each time the particle filter warning light comes on, the vehicle mileage is stored in the following parameter (PR+1).
When all ten parameters have a value other than zero, and the particle filter warning light comes on again, the
distance information for PR784 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR784 DF312 record no. 1 to PR793 DF312 record no. 10 contains a record of the vehicle
mileage when the particle filter warning light comes on. The appearance of fault DF312 Speed request is
associated with each of these parameters.
PR784 to PR793 operate through successive copying (when the particle filter warning light comes on, the value of
PR784 is copied to PR785 DF312 record no. 2, the value of PR785 is copied to PR786 DF312 record no. 3 and
so on).
When there are more than ten records, the value of PR793 is deleted. The new mileage is allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means that no data has
been saved. The parameters appear in the sub-function when they have a value above zero.
