1. DEF: Internal electronic fault
NOTESConditions for running fault finding on a present or stored fault:
Apply this fault finding procedure if the fault reappears as present or stored after the
ignition is switched of f and on again.
Switch off the ignition and wait for the immobiliser warning light (Power-latch) to come one,
–Switch on the ignition again.
–Start the engine and switch on the air conditioning.
If the fault recurs, contact the Techline.
If the fault does not reappear: leave the climate control switched on and select various ventilation and air
distribution settings to check that the system is operating correctly.
–Check that no fault is displayed.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair.
If the computer was replaced (at the request of the Techline), reconfigure the
computer (see Configurations and programming).
Deal with any other faults.

Fault finding - Conformity check
SUB-FUNCTION: PASSENGER COMPARTMENT VENTILATION
NOTESOnly carry out this conformity check after a complete check with the diagnostic tool
(fault reading and configuration checks).
Application conditions: engine stopped with ignition on (12 V APC), AIR
CONDITIONING OFF (air conditioning compressor not activated).
Note:
–Read the parameters when the vehicle is cold (in the morning) to check the
conformity of the temperature parameters (without thermometer). The two
temperatures should be practically the same (as should the coolant temperature
given by the injection system).
–The invalid values given in this check correspond to the value sent by the diagnostic
tool (substitute value) when the sensor in question is faulty. A sensor fault can be
detected when these invalid values are displayed (this is an important point for
sensors on which fault finding cannot be performed, e.g. exterior temperature
sensor).
Delayed illumination of the exterior temperature sensor LCD indicates that an invalid
value has been received concerning the exterior temperature sensor.
