Perform this fault finding procedure if there is a fault in the Command menu, or a
passenger compartment heating/demisting problem.
Refer to the Wiring Diagram Technical Notes for the vehicle to locate the fuses and
relays concerned.

If the additional heater no. 2 relay does not operate when running command AC064:
check the engine management computer connections.
Check the connections of thermoplungers 2 and 3.
Repair if necessary.
Check for + 12 V after ignition supply on connections 3FB and BP91 of component 1068.
If there is no + 12 V supply, refer to the interpretation of fault DF015 Main relay control circuit.
Repair if necessary.
Check the continuity, absence of interference resistance and insulation to earth of connection 3JAA
between components 120 and 597.
If the connection or connections 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 for + 12 V after ignition feed between connections BP91 and 3JAD of component 597 and connection
3JAD of components 1072 and 1073.
Measure the resistance of thermoplungers 2 and 3.
Replace thermoplunger no. 2 or 3 if the resistance is greater than 2 Ω.
Replace the water heater interface unit if necessary.
Using a test light, check that the water heater interface unit is properly earthed on connection 3JAA between
components 120 and 597.
if the fault is present, contact the techline.

ALP 4 Poor performance
NOTESBefore dealing with this customer complaint, check that there are no faults, and
the conformity (or otherwise) of the parameters and statuses using the
diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT
In the event of the engine overheating above 119°C, the computer deliberately limits the fuel flow (warning light is
illuminated when temperature exceeds 115 ° C).
Please observe the cleanliness guidelines and safety advice.
is the engine running on all
cylinders?
NO
Check:
– Check the conformity of the fuel used by running Test 11 Diesel fuel conformity check.
If the diesel fuel is not correct:Replace the diesel fuel.
Change the diesel filter.
Bleed the low and high pressure diesel circuit.
– The conformity of the assembly of the injectors (presence and conformity of the sealing washer).
Checking procedure:
– Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
– If 1 injector protrudes, remove the injector and check that the washer is correct.
– If one injector does not touch the straightedge (clearance of more than 1 mm), remove the injector and check
for the presence of the washer.
– Clean the injector well and the injector, refit the injector with its correct sealing washer.
– The sealing and condition of the inlet circuit, run Test 4 Turbocharged air inlet circuit check.
– The condition of the air flowmeter, run Test 5 Air flowmeter.
Check the turbocharger:
–Run Test 2 Air line at the turbocharger.
–Run Test 6 Turbocharger control solenoid valve check.
–Run Test 7 Turbocharger.
check that the turbocharging pressure follows the increase in engine speed and that the loop difference with the
turbocharging pressure is low.
Otherwise, replace the turbocharger.
YES
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

ALP 9 Particle filter warning light comes on too often
NOTESBefore dealing with this customer complaint, check that there are no faults
except DF312 Speed request and the conformity (or otherwise) of the
"parameters" and "status" using the diagnostic tool. Deal with the other faults
first.
If the customer complaint is not eliminated, perform the following checks.
Have the last 10 regeneration attempts failed?
Is the distance of PR412 Distance of last
successful regeneration less than all the
parameters of group 2? (PR794 to PR803
Regeneration failure record no. 1 to no. 10).

Is at least one status for group 1 = STATUS4?
YES
YESAre all the regeneration
failures linked to engine cut-
off?
