–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
Disconnect the injection computer and check the condition of the contacts and connector.
Repair if necessary.
Display the value of parameter PR041 Turbocharger pressure.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after a series of full-load/no-load actions on the
accelerator pedal.
Special notes:
Turbocharging, Passenger Compartment Heating Resistor activation and cruise
control/speed limiter are not authorised.
If CO.0, CC.1, 1.DEF is present the level 1 warning light is lit.

potentiometer and the engine torque is limited.

Priorities when dealing with a number of faults:
Deal with fault DF011 Sensor supply voltage no. 1 first if it is present or stored.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.

2.DEF
NOTESThe brake pedal has been depressed while the accelerator
is depressed and jammed.
Check the brake light switch.
This is a test procedure designed to detect an accelerator pedal that is jammed in the depressed position. It
monitors the accelerator pedal in relation to the brake pedal.
If the test procedure detects depression of the brake pedal over 600 ms, it registers a fault which is stored in the
computer. While this fault is present (both pedals depressed simultaneously) the engine switches to limp home
mode and the engine speed is set at 1,400 rpm.
Once the fault is no longer present (e.g. brake and accelerator pedals released) safe mode is deactivated and the
engine immediately regains its ability to respond to speed/torque requests.
This fault may occur even if the accelerator pedal is not jammed, if there is driver error during use:
- "Heel-and-toe" type driving,
- Vehicle with driving school option,
The procedure in this case should be to clear the fault and take another reading.
If the fault is still present, check the mechanical condition of the accelerator pedal:
–locked in full load position,
–with the pedal blocked by an external component.
Repair if necessary.
Vary the position of the pedal and refer to the conformity check in order to check the operating values of the
accelerator pedal potentiometer.
If the values displayed are inconsistent, replace the accelerator pedal potentiometer.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
