IGNITION AND INJECTION

DF 061
PRESENT
OR
MEMORIZED
CYLINDERS 1-4 IGNITION COIL CIRCUIT
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 l.
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.
