EOBD management (European On Board Diagnostic):
The EOBD system enables the detection of any faults relating to the vehicle emission control system
(EOBD EURO IV emission control standards exceeded).
This system should be active for the entire life of the vehicle.
1. Conditions for an EOBD fault appearing
An EOBD fault will be detected after 3 driving cycles.
It allows the driver to know whether the vehicle has a fault directly linked to the emission control system.
2. System faults displayed by the EOBD
Only a few faults are indicated by the EOBD system:
– DF002 Air temperature sensor circuit.
– DF004 Turbocharging pressure sensor circuit.
– DF011 Sensor feed voltage no. 1.
– DF012 Sensor feed voltage no. 2.
– DF013 Sensor feed voltage no. 3.
– DF026 Cylinder 1 injector control circuit.
– DF027 Cylinder 2 injector control circuit.
– DF028 Cylinder 3 injector control circuit.
– DF029 Cylinder 4 injector control circuit.
– DF054 Turbocharging solenoid valve control circuit.
– DF056 Air flow sensor circuit.
– DF107 Computer memory.
– DF200 Atmospheric pressure sensor.
– DF209 EGR position sensor circuit.
– DF272 EGR valve control circuit.
– DF569 Turbocharging circuit.
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. Conditions for clearing an EOBD fault
An EOBD fault is cleared in several phases.
The fault present in the diagnostic tool will only be stored (following repair) after the vehicle has been driven
3times.
The EOBD warning light will only go out after these 3 driving cycles.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the EOBD fault and display parameters to be cleared from the computer, the system must go
through 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 EOBD fault will still be present or stored in the injection
computer.
