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.

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.

WARNING
Never drive the vehicle without checking first that there are no throttle valve
faults.
If the starter motor does not operate, there may be a fault with the engine immobiliser.
Carry out a fault finding procedure on the UCH.

Check the condition and conformity of the spark plugs.
Check the mounting, cleanliness and condition of the flywheel signal sensor.
Check the flywheel signal sensor air gap.
Check the condition of the flywheel.
Check that the air filter is not clogged.
Check that the air inlet circuit is not blocked.
Check that there is fuel in the tank (fuel sender fault).
Check that the tank vent is not blocked.
Check that the fuel is of the correct type.
Check that there are no leaks in the fuel system, from the tank to the injectors.
Check that there are no kinked hoses (especially after a removal operation).
Check the fuel flow rate and pressure.
Check the sealing of the injectors, and that they are working properly.
Check that the exhaust system is not blocked and the catalytic converter not clogged.
Check the timing setting.
Check the cylinder compressions.
Check the hydraulic tappets if there is camshaft noise.
AFTER REPAIRRepeat the conformity check from the start.
