ALP 3 Injection noise
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.
If the injection noise occurs after starting from cold:
Check the low pressure diesel circuit priming.
Check the fuel heater supply.
Check the operation of the preheating system.
Check that fuel and engine temperatures are consistent.
If the injection noise occurs at idle speed:
Check the condition of the injector connector and pressure regulator terminals.
Check the conformity of the air flow signal, refer to the interpretation of PR132 Air flow or run Test 4
Turbocharged air inlet circuit check.
If the complaint is still present, perform fault finding on the injectors: run Test 9 Poor injector operation.
does the injection noise occur at all engine speeds?
Run fault finding on the injectors: run Test 9 Poor injector operation.
Check the condition of the injector connector and pressure regulator terminals.
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.
Check the conformity of the air flow signal, use the interpretation of PR132 Air flow.
If the customer complaint is still present:
Run command AC011 Rail pressure regulator,
check the following parameters:
– the conformity of the fuel pressure between PR008 Rail pressure setpoint and PR038 Rail pressure,
– the conformity of the pump fuel flow between PR157 Fuel flow setpoint and PR017 Fuel flow. If the fault is
still present, contact the techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
