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.
