2. System faults displayed by the OBD
Only a few faults are displayed by the OBD system:
– DF001 Coolant temperature sensor circuit.
– DF003 Atmospheric pressure sensor circuit.
– DF011 Sensor supply voltage no. 1.
– DF012 Sensor supply voltage no. 2.
– DF013 Sensor supply voltage no. 3.
– DF038 Computer in 6.DEF EEPROM fault.
– DF040 Cylinder 1 injector circuit in CO Open circuit.
– DF041 Cylinder 2 injector circuit in CO Open circuit.
– DF042 Cylinder 3 injector circuit in CO Open circuit.
– DF043 Cylinder 4 injector circuit in CO Open circuit.
– DF054 Turbocharging solenoid valve control circuit in CC.0 Short circuit to earth.
– DF056 Air flowmeter circuit.
– DF209 EGR valve position sensor circuit.
– DF310 Particle filter upstream temp.* sensor.
– DF315 Particle filter diff.* pressure sensor.
– DF504 Automatic transmission.
– DF621 EGR valve jammed open.
– DF717 Particle filter upstream pressure.
– DF953 Particle filter absent.
Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.
3. OBD fault clearing conditions
An OBD fault is cleared in several steps.
The fault present in the diagnostic tool will only be stored (after a repair operation) after the vehicle has been
driven 3 times.
The OBD warning light will only go out after these 3 trips.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the OBD fault and display parameters to be cleared from the computer, the system requires
40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
– the engine coolant temperature reaches at least 71.1°C,
– the engine coolant temperature varies by 22.2°C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored on the injection
computer.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
This fault only occurs on vehicles with automatic transmission.
Check the oil temperature sensor connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the oil temperature sensor between connections 47Q and 115A.
Replace the oil temperature sensor if the resistance is not approximately:
11 50 Ω at 40°C
308 Ω at 80°C
105 Ω at 120°C
53 Ω at 150°C
Check the insulation, continuity and the absence of interference resistance of the following connections:
– connection code 47Q,
– connection code 115 A.
Between components 120 and 688.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the oil temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is considered present when the engine is running.
Special notes:
If the fault is present:
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (starting
+ 5 seconds + switch off the ignition and wait 1 minute).
Run a multiplex network test (see 88B, Multiplexing).
If the fault is still present, run fault finding on the Automatic transmission system (see21A, Automatic
transmission).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

ET415
CONTINUED 1
STATUS 3
Clutch 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 automatic transmission:
Carry out a multiplex network test, check the configuration of the multiplex network
according to the vehicle's technical definition and, in particular, the automatic gearbox
computer configuration (see 88B, Multiplex).
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either 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, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the right-hand side of the steering wheel.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal indicating that the brake pedal switch has been
pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
– of status ET042 Cruise control/speed limiter,
– of status ET703 Cruise control/speed limiter buttons,
– of status ET704 Brake contact no. 1,
– and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 changes to "STATUS 5", deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6 when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) and:
– If the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is in neutral on an automatic gearbox.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into neutral on an automatic transmission, test
the ABS computer and check the configuration of the tyre size stored in the computer. If
the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 7
Inconsistency between the request and the vehicle speed
Status ET415 changes to STATUS 7 if the computer detects too great a difference
between the speed requested by the driver and the vehicle speed.
This could occur when driving with cruise control active (ET042 Cruise control/ speed
limiter: CRUISE CONTROL) and when there is a significant difference.
This inconsistency deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 changes to STATUS 7 where there is no significant difference in the
levels, contact the Techline.
STATUS 8Automatic transmission in defect mode.
Status ET415 becomes STATUS 8 when driving with the cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the automatic transmission is
in defect mode.
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 automatic transmission
computer.
Deal with any present or stored faults (see 23A, Automatic transmission,
interpretation of faults).
Clear the automatic transmission computer fault memory by running command RZ007
"Fault memory".
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If STATUS 8 is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
