TEST 1 Low pressure circuit check
Check the conformity of the low pressure circuit
connections
Are the low pressure circuit connections correct? Carry out the necessary repairs.
Check the condition of the priming bulb, and that it is
working properly.
Look for leaks at the unions.
Are there leaks from the hoses and unions? Carry out the necessary repairs
Check that there are no air bubbles in the diesel fuel. Bleed the low-pressure circuit.
Place a container under the filter.
– Disconnect the return hose from the filter
and plug the filter.

TEST 3 Injector check
Conduct a visual inspection around the injectors.
Is there diesel fuel around the injectors?Locate the source of the leak and carry out the
necessary repairs.
Control the injectors using the commands:
– AC005 Cylinder 1 injector,
– AC006 Cylinder 2 injector,
– AC007 Cylinder 3 injector,
– AC008 Cylinder 4 injector.
Can you hear the valve moving when you are 1
metre from the vehicle?Check the insulation and the continuity of the
electrical circuit.
Run TEST 9 Diesel filter check.
If TEST 9 is correct, replace the faulty
injector(s) (see MR 388 (Logan/Sandero) or MR
451 (Duster), MR 423 (Thalia 2/Symbol 2) or MR
