TEST 1 Injector test
Part A: Fuel regulation balance check for each injector (individual correction):
– In the CLIP diagnostic tool, choose the Fuel circuit subfunction.
– With the engine idling and the fuel temperature > 50°C, display the flow correction values for each injector
(individual correction), i.e.:
– PR364 Cylinder no. 1 fuel flow correction.
– PR405 Cylinder no. 2 fuel flow correction.
– PR406 Cylinder no. 3 fuel flow correction.
– PR365 Cylinder no. 4 fuel flow correction.
The normal flow correction range per injector is between - 5 mg/stroke and + 5 mg/stroke without reaching
these values.
– If this has not already been carried out, check the injector connections and wiring.
– Check the connections and wiring of the engine management computer to the injectors.
– Repair if necessary.
– Check the IMA injector codes, by comparing the IMA engraved codes on the injectors (the IMA codes are read
from left to right) and the IMA codes read with the Clip diagnostic tool.
– If the IMA codes are correct, continue the fault finding procedure,
– If not, modify the incorrect IMA codes using command SC002 Enter injector codes (see Interpretation of
commands).
To confirm the repair, consult part B of this test.
CASE No. 1: If at least one of these values is equal to or greater than + 5 mg/st
– Check the valve clearance.
– Check the condition of the engine and the compressions (using the Clip diagnostic tool or a compression
gauge).
– If the compression test reveals a cylinder fault, carry out the necessary repairs.
– If the compression is correct, check the fitting conformity of the injector (see MR 364 (Mégane II) or 370
(Scénic II), 13B, Diesel injection, Diesel injector: Removal - Refitting)
In particular, check that each injector has one compression washer.
Check the fuel regulation again for each injector (individual correction).
If not, replace the injector and check for the sealing washer. Modify the IMA code using command SC002 Enter
injector codes (see Interpretation of commands).
–Run Part B of this test to confirm the fault finding procedure.
CASE no. 2: If at least one of these values is less than or equal to - 5 mg/stroke
– Check the valve clearance.
– Check the level and condition of the engine oil.
– Remove the injector with the largest correction.
– If there is diesel fuel contamination, check the condition of the cylinder concerned (cylinder, piston, valves). Use
an endoscope if possible.
– Only replace the removed injector, and modify the IMA code using command SC002 Enter injector codes
(see Interpretation of commands).
–Run Part B of this test to confirm the fault finding procedure.
