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.

ALP 2"Adjust tyre pressure" message lights up (the wheel concerned
fills in on the display)
NOTESCheck that all the faulty tyres are fitted with tyre pressure monitor valves.
Check that the tyres are cold (vehicle immobilised for approximately 2 hours) and if not,
add 0.3 bar to the recommended pressures.
Make sure the tyre has the
recommended pressure as specified
on the label or in the driver's
handbook (not under- or over-
inflated).
Are the tyres at the recommended
pressures?
YES
Read the pressures under PR003 to
PR006
Do PR003 to PR006 match the
readings taken with a pressure
gauge (within 0.2 bar)?
NO
Check the tyre pressure with another
gauge.
Does the new reading indicate
dispersal by the first gauge?
YES
Adjust the tyre pressure, taking into
account the pressure gauge
variation.
Replace the faulty sensor(s).
AFTER REPAIRCarry out a complete check with the diagnostic tool.

one or both rear wheels, intermittent event)
NOTESCheck that all the faulty tyres are fitted with tyre pressure monitor valves.
Use status ET045 RF signal received to check
that the receiving aerial works correctly by
requesting central door locking with the card 4
to 5 metres to the rear of the vehicle, right-hand
side.
If central door locking does not work, check
receiving aerial presence, positioning and
connection on the UCH.
