status ET040 is
INOPERATIVE, refer to
the interpretation of
status ET040.
ET037:Tyre pressure
appropriate for
speedYES, if the pressure is
appropriate for the
vehicle speed.– If status ET037 is NO,
consult the
interpretation of status
ET037.
PR008:Vehicle speedX = 0 (in km/h)If the vehicle speed signal
is incorrect, carry out fault
finding on the ABS.
ET036:Wheel

imbalanceNONE, if the pressures of
the two front-axle and two
rear-axle tyres are
balanced.
(pressure difference
between the two tyres on
the same axle < 0.5 bar)
⇒ Readjust the pressure.
– FRONT, if the
pressures of the two
front tyres are not
balanced.
– REAR, if the
pressures of the two
rear tyres are not
balanced.
– FRONT/REAR, if the
pressures of the two
front-axle and two rear-
axle tyres are not
balanced.
⇒ See the interpretation of
status ET036.
ET045:Radiofrequency
signal receivedNO– Status ET045
becomes YES when the
receiver integrated into
the UCH receives a
signal.
To check whether the
receiver is functioning
normally, carry out a door
locking request with the
card and check that the
status switches to YES.

interpretation of
parameters PR003 to
PR006.
Ensure that the
recommended pressure
values (PR009 to PR012)
are correct for your
vehicle.
Following a battery cut-off,
it is normal that all
temperature values
should be 50 °° ° °
C and
pressure values 0 bar.
Perform a road test so that
the valves emit their true
temperature and pressure
values.
It may be that the
temperatures of all the
tyres are not exactly the
same, depending on the
load distribution and
whether or not they are
exposed to sunlight. PR004:Front right-hand

ALP 1 No dialogue with the computer
NOTESNone
Try the diagnostic tool on another vehicle.
Make sure the tool update version is more recent than CD-ROM No. 32.
Check:
–the connection between the diagnostic tool and socket (connection and cable in good condition).
–the computer power supply
–the engine and passenger compartment fuses.
Make sure that the CLIP sensor is fed by tracks 16 (+ 12 V), 4 and 5 (earth) of the diagnostic socket, which
can be seen by the two red warning lights on the sensor lighting up.
Make sure that the CLIP sensor is connected to the computer's USB port.
Make sure that the CLIP sensor is communicating properly with the vehicle's computers; this can be seen by
the two green diodes on the sensor lighting up.
Check the following tracks on the diagnostic socket:
track 1 + After ignition feed
track 16 + battery feed
tracks 4 and 5 Earth
Repair if necessary.
Check the continuity, insulation and absence of interference resistance on lines:
multiplex line H (diagnostic socket track 6)
multiplex line L (diagnostic socket track 14)
With a multimeter, make sure that the voltages at the diagnostic socket terminals are:
–2.5 V between CAN H (track 6) and the earth (tracks 4 and 5)
–2.5 V between CAN L (track 14) and the earth (tracks 4 and 5)
If dialogue with the UCH still has not been established after all the checks, contact your Techline.
AFTER REPAIRCheck that no faults are still present.
Check that the system is operating correctly.
