I need to deactivate the instrument panel cluster (IPC) backlight on a Fiat Tipo 2016 , but only when the night lights are off, during the day.
The IPC has an internal light sensor, but it works only when the nights lights are on.
I change the byte that comand the cluster internal light sensor ( byte 76 ) , but the lights still remain on, the only difference is that they don’t dimm automatically (with night light on).
If anyone knows if there s a way to do this, or at least activate light dimmer with car lights off.
Byte76 (IPC internal light sensor):
00 --> OFF
04 --> ON
In fact the Fiat Ducato Imala (motorhome) have the opposite problem a few years ago:
