ALP 6"Tyre sensor inoperative" message lights up (disappearance of
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.
NO
Is the aerial correctly positioned and
connected?
YES
If the fault is still present, the UCH is faulty, and
you should contact the Techline.
Replace and reconnect the aerial on the UCH.
