ET004AC AUTHORISED
STATUS DEFINITIONYES: This status indicates that the air conditioning is active.
NO: This status indicates that the air conditioning is inactive.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
YESThe air conditioning authorisation only changes to YES if:
–the air conditioning request has been made by the driver (air conditioning switch in AC
position with minimum ventilation),
–the engine is not under full load,
–the air conditioning system is not faulty.
NOStatus ET004 remains at NO under the following conditions:
–Vehicle stopped with the ignition on,
–faults present in the air conditioning circuit,
–no air conditioning request made by the driver,
–engine under full load.
If status ET004 remains NO then the air conditioning should be authorised; check:
–that the air conditioning compressor is activated correctly,
–the air conditioning system feed fuses,
the presence of refrigerant in the air conditioning circuit.

ET006CODE PROGRAMMED
STATUS DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
NOTESThe injection immobiliser code is not written in the injection computer.
The programming of this code in the injection computer is managed by the UCH.
To carry out programming:
–establish communication with the UCH see 87B, Passenger compartment
connection unit.
–run command SC017 Program injection immobiliser code,
–follow the instructions for the procedure.
As long as this phase has not been completed, ET006 "Code programmed" is "NO".
IMPORTANT:
the immobiliser code is written in the injection computer memory at the end of the
computer auto-feed phase. Do not disconnect the battery before the end of this phase.
Conformity check: Engine stopped, ignition on or engine running.
YESStatus ET006 is YES if dialogue is possible between the UCH computer and the injection
computer and the key code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer and
if status ET003 Immobiliser is INACTIVE.
In the event of a fault, (see 87B, Passenger compartment connection unit,
conformity check).

ET007PRE-POSTHEATING UNIT CONTROL
STATUS DEFINITIONACTIVE: the status is active when the heater plugs are activated according to the
engine coolant temperature.
INACTIVE: the status is inactive after the engine has been running for a certain period.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
Conformity check: Engine running and the engine coolant temperature > 80˚C
ACTIVEWhen the ignition is switched on, status ET007 should be ACTIVE for a time that varies
according to the engine coolant temperature. Both the relay and the heater plugs are
supplied.
After starting the status should remain ACTIVE for a time that varies depending on the
engine coolant temperature. This is postheating.
If ET007 is INACTIVE when the ignition is switched on, check:
–The supply fuse FB1 (70A) of the engine fuse and relay box or F2 (70A) on the power
feed fuse board, according to the vehicle.
–The feed to the heater plugs following relay actuation, and the heater plugs
connections.
–The continuity and the absence of interference resistance between the following
connections:
●Connection code 37Z between components 257 (or 980) and 680.
●Connection code 37AA between components 257 (or 980) and 681.
●Connection code 37AB between components 257 (or 980) and 682.
●Connection code 37AC between components 257 (or 980) and 683.
–That the contacts of the pre-postheating unit connector are in good condition and
connected correctly.
If the vehicle starts, preheating is completed and status ET007 remains ACTIVE during
the engine operating phase, consult the interpretation of faults DF017 Preheating unit
control circuit and DF025 Preheating unit fault finding connection.
INACTIVEIf the vehicle does not start, the status remains INACTIVE and the preheating was not
executed when the ignition was switched on or during the starting phase, check the
following connections:
●connection code 3FY and 3FF between components 120 and 257 (or 980).
Check for + 12 V on the preheating unit.
●Connection code BP35 of component 257 (or 980).
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.

ET042CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITIONNOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off switch
is in the rest (or neutral) position.
LIMITER: This status indicates that the driver has used the main switch to select the
speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system programming
functions.
Conformity check: Engine stopped, ignition on or engine running.
NOT DETECTED If the vehicle is not fitted with cruise control/speed limiter function buttons, status ET042
is permanently NOT DETECTED. This confirms that the cruise control/speed limiter
function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main switch
is in rest (or neutral) position and the injection computer has just been programmed or
reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the cruise
control position and then in the speed limiter position.
Return to rest position.
The tool displays status ET042 INACTIVE.
If not, several steps must be checked:
1. Return to the multiplex network test page on the Clip application. Repeat the
multiplex network test. Re-establish dialogue with the injection computer. Check
status ET042. If ET042 is INACTIVE, the injection computer has detected the
various positions of the main switch. The cruise control/speed limiter is active.
2. If status ET042 is still NOT DETECTED, check that the vehicle's owner has not had
the cruise control/speed limiter function disabled in the past. Contact the Techline.
