NOTESSpecial notes:
If DF130, the engine may stop with the level 1 and 2 warning lights illuminated along
with the message Faulty injection.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine running.
Check the connection and condition of the of the fuel flow actuator connector (IMV), and repair it if necessary.
Measure the resistance between tracks 1 and 2 of the flow actuator.
Replace the flow actuator if the resistance is not 5.3 Ω ± 0.5 Ω at 20°C.
Check the connection and condition of the computer 48-track brown connector B.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer connector B track M4 track 1 fuel flow actuator
Repair if necessary.
Check that there is fuel present in the tank and that it is correct. Run Test 13 Diesel fuel conformity check.
Run Test 1 Low pressure circuit check.
Run Test 6 High pressure system check.
Repair if necessary.
