Conformity check with engine stopped and ignition on
INACTIVE
Status ET088 is INACTIVE when there has been no air conditioning request and
when compressor activation has not been authorised (ET004 Air conditioning
authorisation is NO or when the driver switches off the air conditioning).
If compressor activation has been requested and status ET088 remains INACTIVE
(see 62A, Air conditioning).
Note:
Compressor operation is only authorised when the engine is running.
Compressor switch-on is finally requested by the Protection and Switching Unit
(Vdiag 18, 1C, 20 only).
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

ET143
LOW-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS DEFINITIONACTVE: This status indicates that the low-speed fan assembly relay is actuated.
INACTIVE: This status indicates that the low-speed fan assembly relay is not actuated.
NOTESIf the vehicle is fitted with air conditioning, the fan assembly electrical circuit contains
2 relays. The fan assembly speed 1 relay will be actuated when the engine coolant
temperature exceeds 96° and will be dedicated to cooling the engine as long as the
engine coolant temperature does not exceed 99°.
If the engine coolant temperature exceeds 99°, fan assembly speed 2 relay will be
actuated and the engine cooling fan will run more quickly.
ACTIVE
When the coolant reaches 96°C, the diesel computer actuates the low-speed fan
assembly relay and status ET143 becomes ACTIVE.
The relay then supplies the fan assembly and the cooling fan begins to turn.
Run command AC038 Low-speed fan unit relay and check visually that the cooling
fan is turning.
If this is not the case, carry out the following operations:
– check the condition of fuse FM15 (60A) and the motor relay R09,
– disconnect the low-speed and high-speed relays, check their operation and the
condition of the connections.
– repair if necessary,
– check for a + 12 V on connection 3FB of the low speed relay when it is actuated
then check the continuity and the absence of interference resistance on connection
3JN between components 120 and 597.
If the connection or connections are faulty and there is a repair method (see Technical
Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair), repair the
wiring, otherwise replace it.
INACTIVEIf the engine temperature is less than 96°C, the engine cooling fan cannot switch on
and the low-speed fan assembly relay cannot be actuated.
Sta tus ET143 becomes INACTIVE when the control relay and the engine cooling fan
are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

HIGH-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the high-speed fan assembly relay is actuated.
INACTIVE: This status indicates that the high-speed fan assembly relay is not
actuated.
ACTIVE
When the coolant reaches 99°C, the diesel computer activates the high-speed fan
assembly relay and status ET144 becomes ACTIVE.
The relay then supplies the fan assembly and the cooling fan begins to turn.
Run command AC039 High-speed fan unit relay and visually check that the cooling
fan is turning. If this is not the case, carry out the following operations:
– check the condition of fuse FM15 (60A) and the motor relay R10,
– disconnect the fan unit relays, check their operation and the condition of the
connections,
– repair if necessary,
– check for a + 12 V on connection 49B of components 597 and 262, when the high-
speed relay is actuated.
Check the continuity and the absence of interference resistance on the following
connections:
–Connection codes 3JP and 49B between components 120, 957 and 262.
If the connection or connections are faulty and there is a repair method (see Technical
Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair), repair the
wiring, otherwise replace it.
INACTIVEIf the engine temperature is less than 99°C, the engine cooling fan cannot switch on
and the high-speed fan assembly relay should not be actuated.
Status ET144 becomes INACTIVE when the control relay and the engine cooling fan
are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

– check the condition of the cruise control/speed limiter +/- button and the condition of
its connector.
– check the condition of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.

removal-refitting).
Measure the resistance of the following connections while pressing the "+" button
(on the button tracks):
– Connection code86G, of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
