NOTESOnly refer to this customer complaint after a full check of the multiplex network
and the air conditioning with the fault finding tool.
Special notes:
With the ignition on, the control panel screen is permanently on but the panel buttons
only light up when the sidelights are switched on.
Note:
If the external temperature sensor is faulty, the climate control computer is
switched on 5 seconds after the ignition is switched on (this allows a fault to be
identified as fault finding cannot be performed on the external temperature sensor
by the UCH).
Is the fault common to other components (instrument panel,
multifunction display, electric window buttons, etc.)?
YES
Switch on the ignition and switch on the side lights to check
there is a 12 V supply on track 6 of the brown 12-track
