Dacia Solenza (engine E7J). Manual - part 35

IGNITION AND INJECTION

17 - 46

Conditions for diagnostic application to memorized failure:
Set the contact on.

* If the failure is memorized with OBD indicator on, check in the context
part, if state “ET255 : Idling adjustment circuit” corresponding to the
OBD indicator lighting request is affirmative. In this case, proceed as
per bellow mentioned method.

RECOMMENDATIONS

After repairing the step-by-step engine for idling adjustment, it may possible
that engine is not starting; in this situation, the “learning” stage of the adaptive
values by the injection computer must be again performed (see chapter “
Enriching adaptive correction”).
Fix any other possible failures then perform a conformity checking by means of
the CLIP tester.

IDLING ADJUSTMENT CIRCUIT
1.DEF : Open circuit or short-circuit
CO : Open circuit
CC.O : Short-circuit at mass
CC.1 : Short-circuit at +12 volts

Check the connection and condition of the step-by-step engine connector for idling adjustment
Replace the connector if necessary.

Check the resistance of the step-by-step engine for idling adjustment. Refer to chapter “Help” in
order to compare the measured resistance values with the recommended ones.
Replace the step-by-step engine valves if necessary.

Check the insulation, continuity and absence of the parasite resistance on lines:

Pin 12 injection computer > pin B step-by-step engine for idling adjustment
Pin 41 injection computer > pin A step-by-step engine for idling adjustment
Pin 42 injection computer > pin C step-by-step engine for idling adjustment
Pin 72 injection computer > pin D step-by-step engine for idling adjustment

Fix if necessary.

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

1.DEF : Open circuit or short-circuit
CO : Open circuit
CC.O : Short-circuit at mass
CC.1 : Short-circuit at +12 volts

Conditions for diagnostic application to memorized failure:
Start the engine and stop it immediately as the failure is occurring as being
present (risk for catalyst) or rotate de engine with the starter, without starting it,
for 10 seconds.

In case of failures addition, treat as most important, failure “ DF345 : Supply 5
volts potentiometers or sensors “ and failure “DF261: Fuel pump relay circuit”,
if it is /they are present

* If the failure is memorized with OBD indicator on, check in the context part, if
state “ET282 : Ignition coil 1-4 circuit” corresponding to the OBD indicator
lighting request is affirmative. In this case, proceed as per bellow mentioned
method

Check the connection and condition of the coil connector .
Replace the connector if necessary.

Check the resistance of the coil resistance of cylinders 1-4. Refer to chapter
“Help” in order to compare the measured resistance values with the recommended
one.
Replace the coil if necessary.

Check the +12 Volts supply existence after fue

l pump relay, at pin C of the coi

If it is necessary, apply the methodology for failure diagnostic “DF261”
Connect the 90 ways terminal box instead of the injection computer then check
the insulation and continuity on line:

pin 32 injection computer

> pin A ignition coil.

Fix if necessary.

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

RECOMM

ENDA

TIONS

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.

Replace the connector if necessary.

Check the resistance of the coil resistance of cylinders 2 and 3. Refer to
chapter “Help” in order to compare the measured resistance values with the
recommended one.
Replace the coil if necessary.
Check the +12 Volts supply existence after fuel pump relay, at pin C of the
coil.

RECOMMENDATIONS

Conditions for diagnostic application to memorized failure:
Perform a drive test and notice the vehicle speed.
Continue to perform the drive test uphill at constant speed.
Continue to perform the drive test uphill, the acceleration pedal not being
pushed.

* If the failure is memorized with OBD indicator on, check in the context
part, if state “ET223 : Vehicle speed transducer circuit” corresponding to
the OBD indicator lighting request is affirmative. In this case, proceed as
per bellow mentioned method

Check the connection and condition of the speed transducer connector .
Replace the connector if necessary.

Connect the 90 ways terminal box instead of the injection computer then check the insulation,
continuity and the absence of the parasite resistance on line 53 of the injection computer on line.

If the problem is persisting, replace the speed transducer.
