Fault finding - Conformity check62B
MAIN SCREEN
NOTESOnly carry out this conformity check after a full check using 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:
This page lists the statuses and parameters provided by the climate control computer
but which are not associated with the three sub-functions given in the conformity
check (PASSENGER COMPARTMENT VENTILATION, COLD LOOP and HEATING
sub-functions).

SUB-FUNCTION: PASSENGER COMPARTMENT VENTILATION
NOTESOnly carry out this conformity check after a full check using the diagnostic tool
(fault reading and configuration checks).
Application conditions: engine running, AIR CONDITIONING ON (air conditioning
compressor 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).

ET002
+ 12 V SIDE LIGHTS FEED
NOTESNone
This status indicates the presence of + 12 V side lights feed on connection LPD of component 419.
If ET002 displays ABSENT when the side light are lit, check for + 12 V between connection LPD and the earth
connection NAM of component 419.
If + 12 V is present on connection LPD and ET002 displays ABSENT.
If the status does not operate, carry out fault finding on the UCH (see 87B, UCH).
If + 12 V is not present on connection LPD, consult ALP No. 13.
AFTER REPAIRRepeat the conformity check from the start.

NOTESNone
This indicates the status of the compressor actuated by the injection computer.
If ET020 displays ACTIVE, the compressor activation request is authorised.
If ET020 displays INACTIVE, the compressor activation request is not authorised.
If the “AC” indicator light is lit and if ET020 displays INACTIVE, run fault finding on the injection computer
(see 13B, Diesel injection or 17B, Petrol injection) and UCH (see 87B, UCH).
AFTER REPAIRRepeat the conformity check from the start.
