PARTICLE FILTER TEMPERATURE SENSOR FAULT FINDING
NOTESCarry out this command only under the following conditions:
– DF999 Particle filter downstream temperature sensor circuit,
– DF1000 Particle filter upstream temperature sensor circuit,
With the ignition on and engine switched off and the engine coolant temperature
below 40°C.
This command is used to check the operation of the particle filter temperature sensors.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
If one of the faults such as DF999 Particle filter downstream temperature sensor circuit or DF1000 Particle
filter upstream temperature sensor circuit is stored, check if it is in short circuit to the + 12 V or in open circuit
using this command.
Procedure:
– Run command AC239 Particle filter temperature sensor fault finding in the presence of the one of these
two faults DF999 Particle filter downstream temperature sensor circuit and/or DF1000 Particle filter
upstream temperature sensor circuit.
– If one or both of these faults becomes present, then the sensor(s) is in short circuit to + 12 V or in open
circuit.
Refer to the interpretation of faults DF999 Particle filter downstream temperature sensor circuit and DF1000
Particle filter upstream temperature sensor circuit.
– If they do not become present, clear the faults on the CLIP diagnostic tool.

ALP 1 No dialogue with the computer
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network.
Check the voltage of the battery.
If the battery voltage is not between:
9.5 V < Battery voltage < 17.5 V

– Check the injection computer earths (quality, oxidation, tightness of earth bolts on the battery terminal).
– Check that the supply to the computer is correct:
Earth on code connection N* 2 of the computer connector.
+After ignition feed on connection code AP of the computer connector.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the power supply to the diagnostic socket is correct:
+ before ignition feed on track 16
+ after ignition feed on track 1
Earth on tracks 4 and 5
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If dialogue has still not been established after these checks, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
