DEFINITIONACTIVE: This status indicates that the downstream oxygen sensor heater is active.
INACTIVE: This status indicates that the downstream oxygen sensor heater is inactive.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: engine stopped and ignition on.
"INACTIVE"The status is inactive when the engine is off.
In the event of a fault, apply interpretation of DF083 Downstream oxygen sensor
heating circuit.
Conformity check: engine running at idle speed, engine coolant temperature > 80˚C.
"ACTIVE"The status becomes active when the engine is started and its operation increases
according to the heating temperature.

1 RECOGNITION
–Completed
–Not completed
STATUS
DEFINITIONCOMPLETED: This status indicates that the cylinder 1 injector command recognition
is active.
NOT COMPLETED: This status indicates that the cylinder 1 injector command
recognition is inactive.
NOTESThere must be no present or stored faults.
Special notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running at idle speed, and engine coolant
temperature > 80˚C.
COMPLETED
or
NOT
PERFORMEDThe status is completed when the engine is started if the engine phasing is correct.
Run command RZ005 Programming and program the engine flywheel target
(see Configurations and Programming). Check the programming using ET089
Flywheel target programming.
Engine phasing:
On engines without a camshaft sensor, the engine phasing is performed by software. A "Memo-phasing" program
is run first to phase the engine management on starting according to the data saved from the previous setting. Wait
30 seconds (for the data to be saved) before disconnecting the computer.
Then, a second program confirms the first decision. It is based on torque analysis. The torque calculation is based
on the analysis of the time taken for the engine flywheel teeth to pass by. The engine speed should be between
320 rpm and 5,000 rpm.
Run command RZ005 Programming and program the engine flywheel target (see Configurations and
Programming). Check the programming using ET089 Flywheel target programming.

STATUS
DEFINITIONDETECTED: This status indicates that the engine flywheel signal is detected.
NOT DETECTED: This status indicates that the engine flywheel signal is not detected.
NOTESThere must be no present or stored faults.
Special notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: engine stopped and ignition on.
NOT DETECTEDThe engine flywheel signal is detected after the engine is started.
In the event of a fault apply the interpretation for DF154 Flywheel signal sensor
circuit.

ET077IMPACT DETECTED–No
–Yes
STATUS
DEFINITIONNO: This status indicates that the airbag computer has not detected an impact.
YES: This status indicates that the airbag computer has detected an impact.
NOTESThere must be no present or stored faults.
Special notes:
The fault appears when the UCH receives a frontal impact signal from the Airbag
computer via the multiplex network.
As soon as the UCH receives this signal, engine operation is prohibited.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
"NO"The status is usually NO as no impact has been detected.
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).
"YES"If YES an impact must be present.
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).
If the vehicle has been involved in an accident:
Carry out any necessary repairs:
–switch off the ignition for 10 seconds,
–switch on the ignition again.
If status ET077 is YES, run fault finding on the airbag computer (see 88C, Airbags and pretensioners).
If the vehicle has not suffered an accident, run fault finding on the airbag computer (see 88C, Airbag and
pretensioners).
