Test conditions: Engine switched off, after ignition feed on, tyres inflated to correct
pressure.

status ET040 is
INOPERATIVE, refer to
the interpretation of
status ET040.
ET037:Tyre pressure

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

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.

NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Special notes: If a tyre pressure sensor is present in the wheel, precautions must
be taken when removing/refitting tyres. Failure to take the precautions specified
in Section 35 of the Workshop Repair Manual could result in the sensor being
damaged, and potential operating faults in the tyre pressure monitor.
OK:
Absent:
Over-inflated:
Punctured:
Under-inflated: The sensor is operating correctly and the pressure is correct.
The sensor does not transmit or is not present on the vehicle.
The sensor sends a "tyre over-inflated" signal.
The sensor sends a "tyre very under-inflated" signal (recommended pressure 0.6 bar) or a
rapid pressure loss signal.
The sensor sends a "tyre under-inflated" signal.
Make sure the signal sent by the sensor corresponds to the pressure measured with the pressure gauge.
If it does not, inflate or deflate the tyres and check that they change status.
IMPORTANT
Wait 90 seconds before checking the change of status.
Original status = over-inflated
Original status = punctured or under-
inflatedDeflate
InflateFinal status = OK or punctured or under-
inflated
Final status = OK or over-inflated
If the status still displays an incorrect signal as compared to the tyre inflation level, refer to the fault finding chart.
–If the original status is: over-inflated or under-inflated
See ALP 2 and 3 Pressure adjustment.
–If the original status is: Punctured
See ALP 7 Puncture: change the tyre.
–If the original status is: Absent
See ALP 4, 5 and 6 Sensor out of order.
–If the status does not change, replace the sensor on the wheel concerned by following the instructions and
programming procedure for the four valve codes, SC002 Program four valve codes (see Configuration and
programming).
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

TYRE PRESSURE MONITOR SYSTEM
NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Check that no fault is present.
ACTIVE: If the four wheel valves transmit their signal and the signal is correctly received by the UCH.
INOPERATIVE: If a component is faulty or incorrectly configured.
Check in the configuration reading menu to ensure that configuration LC017 tyre pressure monitor has been
properly entered in the UCH. If this is not the case, start configuration in the "Programming" menu with
command CF023 Tyre pressure monitor, under SC008 UCH type.
Check that there is no ABS fault.
Use status ET045 RF signal received to check that the receiving aerial works correctly by trying central door
locking with the card at 4 to 5 metres to the rear right-hand of the vehicle.
If central door locking does not work, check aerial presence and positioning on the UCH.
If, after performing all these checks, no fault has been found and status ET040 is still Inoperative, contact
Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

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.
