ET415
(CONTINUED 4)
STATUS 10Monitoring by injection computer
Status ET415 becomes STATUS 10 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) if the injection computer detects a
fault anywhere in the engine management system, or an engine speed that is too high
or too low.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then run fault finding on the injection computer.
Deal with present or stored faults (see Interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status 10 continues, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

ANTI-PINKING CORRECTION
NOTESThere must be no present or stored faults.
The pinking sensor must not supply a zero signal, proving that it is recording the mechanical vibrations
of the engine.
Check that there is the correct fuel in the fuel tank.
Repair if necessary.
Check the condition and conformity of the spark plugs.
Repair if necessary.
Check the tightness of the pinking sensor.
Repair if necessary.
Check the cleanliness and the condition of the pinking sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer, connectorB, track B3 track 2 of the pinking sensor
Injection computer, connectorB, track B4 track 2 of the pinking sensor
Injection computer, connectorB, track B2Pinking sensor shielding
Repair if necessary.
If the fault is still present, replace the pinking sensor.
AFTER REPAIRRepeat the conformity check from the start.

If the idle speed is not stable, check:
– the timing adjustment,
– the hydraulic tappets if there is camshaft noise (seeMR 364 Mechanical, 11A, Top and front of engine),
– the cylinder compression's.
Drive the vehicle to check the repair.

RUN OBD TEST: CATALYTIC CONVERTER
NOTESIMPORTANT:
Do not perform this test with a new catalytic converter.
Repair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
Check the appearance and condition of the catalytic converter.
Check there are no air leaks, thermal shock, misfiring, coolant or oil consumption.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The purpose of this command is to determine the condition of the catalytic converter
Procedure:
– Engine stopped.
– Run command SC006.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the catalytic converter.
If the result is Status 3: the catalytic converter is in good condition.

RUN OBD TEST: O2 SENSOR
NOTESRepair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The aim of this command is to detect a fault causing the EOBD* threshold for pollutant emissions to be exceeded.
There are two kinds of oxygen sensor damage:
– mechanical damage to the component (breakage, cut in wire) which leads to an electrical fault,
– chemical or thermal damage to the component leading to a slower response time of the sensor and to the
increase in the average reaction time.
Procedure:
– Engine stopped.
– Run command SC007.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
Fault finding is entirely autonomous. When completed, the throttle control ceases and the engine returns to idling
speed regulation operation.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the sensor.
If the result is Status 3: the sensor is in good condition.
