323002756 - 1056BA INJECTOR OPERATION CHECK

STEPCHECK TO BE PERFORMEDREMEDIAL ACTION IF THE CHECK IS NOT OK
1Injection signal checkPrepare the diagnostic equipment for a voltage graph assimilation. Select the "VOLTMETER" function from the "INSTRUMENT" menu with the time set at 1 second.Connect the probes between the pins of the injector that is not working (using disconnector AD 233 N° 1806387000). Press the START button on the diagnostic equipment to begin downloading a graph. Let the engine be driven and check that the signal corresponds to the enclosed graphRenew the wiring between the engine management control unit and the injectors. If the signal is interrupted at the control unit output replace the engine management control unit    Op. 1056B82 INJECTION/IGNITION SYSTEM E.C.U. (ONE) - R + R
2Injector power supply checkCheck that the injectors are correctly suppliedMove on to Step 3Renew the 15A fuse F22 in the engine compartment junction unit after having identified the cause of the problem. Restore the correct power supply for the injectors
3Injector resistance checkDisconnect the injector connectorConnect the Examiner in ohmmeter mode between the injector terminals and then check the resistance: the value should be 12 Ohm ± 10% at 20°CReplace the injector    Op. 1056B70 INJECTOR (ONE) - R + R WITH FUEL MANIFOLD PIPE REMOVED - INCLUDES SEAL REPLACEMNT
