Dacia Solenza (engine E7J). Manual - part 31

IGNITION AND INJECTION

17 - 30

AFTER

REPARATION

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.

Check the battery and electric mass condition of the vehicle.
Fix if necessary.

Check the connection and the connector condition of the actuator

s relay.

Change the connector if necessary.

Check the presence of +12 Volts at pin 1 actuators relay.
Fix if necessary.

Check the actuators relay coil.
Replace the actuators relay if necessary.

Check the insulation and continuity on line

Pin 39 injection computer > pin 2 actuators relay.

Fix if necessary

If the problem is persisting after these checking, fix the other failures then perform the conformity
checking.

RECOMMENDATIONS

Conditions for diagnostic application for memorized failure:
Set the contact on then enter in dialog with the injection computer by means
of the CLIP tester.

REMARK: This failure is of high importance. It is then necessary to be
treated before the following ones.

No comments failure

RECOMMENDATIONS

Conditions for diagnostic application for memorized failure:
Failure is declared present further to a 10 seconds timing with engine running
and climate control under operation, state ET009: active (during test, battery
voltage must be not under 11 V).

AFTER

REPARATION

Diagnostic – Failures interpretation

Connect the 90 ways terminal box instead of the injection computer then check the insulation,
continuity and absence of the parasite resistance on line 32 of the injection computer.
Fix if necessary.

Refer to climate control diagnostic if the incident is persisting.

CANISTER PURGING VALVE CIRCUIT
1.DEF : Open circuit or short-circuit
CO : Open circuit
CC.O : Shot circuit at mass
CC.1 : Short circuit at + 12 V.

RECOMMENDATIONS

Conditions for diagnostic application for memorized failure:
Set the contact on or launch commend “AC016: Canister Purging Valve”
In case of

failures addition, treat a

s most important failure

“DF009 actuators

relay control circuit”.

* If the failure is memorized with OBD indicator on, check in the context part,
if state “ET117 : Canister purging control” corresponding to the OBD i

ndicator

lighting request is affirmative. In this case, proceed as per bellow mentioned
method.

Check the connection and the connector state of the canister purging valve.
Change the connector if necessary.

Check the resistance of the canister purging valve.
Replace the canister purging valve if is necessary.

Check with the contact on, the presence of +12 Volts at pin 1 of the purging valve.
Fix if necessary.

Connect the 90 ways terminal box instead of the injection computer then check the insulation and
the continuity of the line:

Pin 4 injection computer > pin 2 canister purging valve

Fix if necessary

Replace the canister purging valve if necessary.

If the problem is persisting after these checking, fix the other failures then perform the conformity
checking.

RECOMMENDATIONS

In order to perform this diagnostic, the pressure sensor must be not in
failure.
Conditions for diagnostic application for memorized failure:
Set the contact off and wait until the communication computer-CLIP tester
is lost.
Set the contact on, enter in dialog with the computer and erase the memorized
failures. Act upon the starter for 10 seconds or make the engine idle running.

* If the failure is memorized with OBD indicator on, check in the context
part, if state “ET276 : Engine flywheel tooting damage” corresponding to
the OBD indicator lighting request is affirmative. In this case, proceed as
per bellow mentioned method.

AFTER

REPARATION

RPM SIGNAL INFORM

ATION

1. DEF : Engine flywheel tooting damage
2. DEF: tooth signal absence

Check the connection and the condition of the RPM sensor connector
Replace the connector if necessary.

Check the cleaning state and the correct attachment of the RPM sensor
Fix if necessary.

Check the resistance of the RPM sensor.
Replace the RPM sensor if necessary.

Connect the 90 ways terminal box instead of the injection computer then check the insulation,
continuity and absence of the parasite resistance on lines:

Pin 54 injection computer > pin A RPM sensor
Pin 24 injection computer > pin B RPM sensor

Fix if necessary.

If 1. DEF is occurring, check the engine flywheel condition.

If the problem is persisting after these checking, fix the other failures then perform the conformity
checking.

Diagnostic – Failures interpretation

DF017

PRESENT

MEMORIZED

Check that state “ET202: Diagnostic OBD combustion misfires taken into
consideration”, is ACTIVE. Contrary, it is necessary, the re-activation of “learning”
the RPM signal by the injection computer.
Fix the others possible failures and then perform the conformity checking.
