Meter Illumination does not Dim at Night
DESCRIPTION
In this circuit, the combination meter assembly auto dimmer signals from the
main body ECU using the CAN communication system (CAN V1 Bus). When the combination
meter assembly an auto dimmer signal, it dims the meter illumination (warning and
indicator lights). The main body ECU ( ...
