ET056DOUBLE RICHNESS LOOP
STATUS
DEFINITIONACTIVE: The status indicates that the double richness loop is active.
INACTIVE: The status indicates that the double richness loop is inactive.
NOTESThere must be no present or stored faults.
Special notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running at idle speed, and engine coolant
temperature > 80˚C.
"INACTIVE"
or
ACTIVEThis status is only inactive if one of the two oxygen sensors is in poor condition.
In the event of a fault, apply the interpretation of faults DF082 Upstream oxygen
sensor heating circuit, DF083 Downstream oxygen sensor heating circuit,
DF092 Upstream oxygen sensor circuit, DF093 Downstream oxygen
sensor circuit.

ET088REQUEST TO START COMPRESSOR
STATUS
DEFINITIONACTIVE: This status indicates that the compressor is engaged.
INACTIVE: This status indicates that the compressor is not engaged.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Engine running, engine coolant temperature > 80˚C
"ACTIVE"The air conditioning request has been made by the driver when pressing one of the
air conditioning controls (Auto or AC).
Status ET088 becomes ACTIVE and the computer authorises or does not authorise
air conditioning depending on the operating conditions.
If status ET088 does not become ACTIVE when the control button is pressed, refer
to the air conditioning fault finding note (see 62A, Heating system, 62B, Climate
control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.
Conformity check with engine stopped and ignition on.
"INACTIVE"When the driver deactivates the air conditioning, status ET088 must become
INACTIVE.
If it does not, refer to the air conditioning fault finding note (see 62A, Heating system,
62B, Climate control or 62C, Manual air conditioning).
Note: Compressor operation is only authorised when the engine is running.

STATUS
DEFINITIONThis status indicates that the low-speed fan assembly relay is being actuated (ACTIVE)
or not (INACTIVE).
NOTESSpecial notes:
–Perform these checks if the parameters correspond with the system operation
programming.
–If the vehicle is equipped with air conditioning, the engine cooling fan will run at 1
st
speed as soon as the air conditioning compressor is activated.
There should be no fault detected on the coolant temperature sensor circuit when this
fault finding procedure is being carried out.
Conformity check with engine stopped and ignition on.

In the event of a fault, consult the interpretation of fault DF559 Low-speed fan
assembly control.

–that the low-speed fan resistance is correct,
–the cleanliness of the low-speed fan earth,
–the low-speed fan feed,
–the feed line between the low-speed fan and the low-speed fan relay.
Check the connection and condition of the connector of the low-speed fan assembly relay (component code 700)
and of the engine management computer (component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise change the wiring.
