Perform the operations from ” recommendations” for reparation confirmation.
Fix any other possible failures.
Erase the failures memorized by the injection computer.
Perform a conformity checking by means of the CLIP tester.
AFTER
REPARATION
DF 053
PRESENT
OR
MEMORIZED
Check the connection and condition of the injector 2 connector.
Replace the connector if necessary.
Check the injector 2 resistance. Refer to chapter “Help” in order to compare the resistance values.
Replace the injector if necessary.
When setting the contact on, check the presence of sup12 V on pin 1 of the injector 2.
Fix, if necessary the electric routing up to actuators relay.
Connect the 90 ways terminal box instead of the injection computer then check the insulation and
continuity on line :
pin 90 injection computer > pin 2 injector 2
Fix if necessary.
If after these checking the problem is persisting, treat the other failures then perform the
conformity checking.
RECOMMENDATIONS
Conditions for diagnostic application to memorized failure:
Start the engine and especially stop it immediately the failure is becoming
present, so that catalyst-damaging risk is avoided.
In case of failures addition, treat as most important, failure “ DF009 actuators
relay control circuit”
* If the failure is memorized with OBD indicator on, check in the context part,
if state “ET279 : Cylinder 2 injector circuit” corresponding to the OBD
indicator lighting request is affirmative. In this case, proceed as per bellow
mentioned method
Diagnostic – Failures interpretation
CYLINDER 2 INJECTOR CIRCUIT
1. DEF : Open circuit or short-circuit
CO : open circuit
CC.O : shot circuit at mass
CC.1 : short circuit at + 12 V.
