4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily clear the cause of a fault.
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the protectors, insulation, and routing of the wiring, as well as the mountings.
Physical inspection
When working on wiring, use the diagnostic tool to highlight a change in the status of the faults, from a "stored"
fault to a "present" fault, or use the multimeter to view the status changes.
Make sure that the connectors are firmly secured.
Apply light pressure to the connectors.
Twist the wiring harness.
Checking insulation to earth
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5V. The correct measured value is 0V.
Checking insulation in relation to + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value is 0V.
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result is: 1 Ω ± 1 Ω for each connection. The line must be fully checked,
and the intermediate connections are only included in the method if this saves time during the fault finding
procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured value
should be 1 Ω ± 1 Ω.
Power supply check
This check can be carried out using a test light (21 W or 5 W depending on the maximum permissible load).

Fault finding – Interpretation of parameters13B
PR1012WEIGHT OF SOOT AFTER REGENERATION
PARAMETER
DEFINITIONThis parameter indicates the weight of soot, in g, in the particle filter after a
regeneration.
NOTESConsult this parameter after using SC017 Particle filter regeneration.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C without electrical consumers.
If PR1012 is less than 15 g, the particle filter regeneration completed correctly.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration (see interpretation of commands).
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool down
for 2 hours with the bonnet open.
Do not carry out the usual engine oil change before a second After-Sales regeneration (see SC017 Particle filter
regeneration).

IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool down
for 2 hours with the bonnet open.
Do not carry out the usual engine oil change before a second After-Sales regeneration.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
For the other VDiag:
–Consult PR848 Number of regeneration failures. If PR848 is greater than 3, change the engine oil.
●Particle filter too full - replace the particle filter: regeneration has failed. The weight of soot in the particle
filter is so great that it is creating back-pressure. Deal with any faults that appear or replace the particle filter.
Run command SC036 Reinitialise programming and select After particle filter replacement.
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–Then switch on the ignition again, clear the present or stored faults from the computer memory (operation
to be carried out within 3 minutes of switching on the ignition).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
– For the other Vdiags:
–Consult PR848 Number of regeneration failures. If this parameter is greater than 3, it is essential to change
the engine oil.
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D
in the interpretation of DF312 Speed request.
