FLYWHEEL SIGNAL
NOTESThere must be no present or stored faults.
Information:
If the flywheel has been replaced or removed, reinitialise the flywheel target
programming.
Check the mounting and positioning of the TDC sensor (see MR 364 Mechanics, 10A, Engine and
peripherals).
Repair if necessary.
Check the cleanliness and condition of the TDC sensor and its connections.
Check the condition of the wire.
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 E4 Track 2 of the TDC sensor
Injection computer, connectorB, track F3 track 1 of the TDC sensor
Repair if necessary.
Measure the resistance of the TDC sensor between tracks 1 and 2.
Replace the sensor if the resistance is not 200 to 270 at 23 °C.
If the sensor has been replaced, reset the flywheel signal programming.
Flywheel signal programming reinitialisation procedure:
Accelerate up to 4000 rpm in third gear ratio, then decelerate to power take-up speed*.
Then repeat immediately.
(* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.)
If the fault is still present, check the cleanliness and condition of the flywheel.
AFTER REPAIRIf the TDC sensor has been replaced, reinitialise the programming (RZ005).
Repeat the conformity check from the start.

ET415
1(CONTINUED)
STATUS 2Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and the brake pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 2 without depressing the brake pedal, consult the
interpretation of statuses ET704 Brake switch no. 1 and ET705 Brake switch no. 2.
STATUS 3Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405: Clutch pedal.
If the vehicle is fitted with an automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation to
the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing)
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated whenever the suspend button is
pressed.
Status ET415 becomes STATUS 4 while driving when:
- the cruise control is active, or
- The speed limiter is active,
- and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 4 without pressing the 0 button, consult the
interpretation of status ET703 Cruise control/speed limiter buttons and run fault
finding on the R/0 control button located on the right-hand side of the steering wheel.
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

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.

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.
