MATCHING THE VALVE TO THE TYRE
Whenever wheels are swapped over, reprogram the new valve positions in the UCH using the diagnostic tool.
The coloured rings will then have to be placed back in the location marked on the label on the driver's door.
Ring colours:
–Front left-hand: green.
–Front right-hand: yellow.
–Rear left-hand: red.
–Rear right-hand: black.
WINTER AND SUMMER TYRES
On leaving the factory, it is the summer wheel set that is configured in the UCH, but customers can fit their vehicle
with a winter set (winter wheels = wheel rims + sensors + special tyres).
The first time a set of winter wheels is fitted, program the codes of the four valves. Thereafter, whenever the set of
tyres is changed, recognition is automatic without having to touch the UCH.
Establishing communication between the UCH and the CLIP diagnostic tool:
–Connect the wire to the diagnostic socket and switch on the ignition.
–Switch on the diagnostic tool.
–Select the vehicle type and carry out the multiplex network test.
–Select the Tyre function.
–Follow the fault finding procedure described previously.
