NOTESFor radio versions with remote display.
The radio operates but the display does not
light up.
Check the functions of the display that are not
connected to the radio by switching on the “+
side lights feed” (screen backlighting and
exterior temperature).
Does the backlighting or exterior temperature
display work?
YES
Check the continuity and insulation of the wiring
between the radio and the display using a
multimeter (see Wiring Diagrams Technical
Note for New Twingo, code 261).
