Control Unit
See "Stop lights check".
Rear fog lights check
Control unit N59 is connected to the rear
fog light power supply - fuse F11 and
relay I25, both in the fusebox G1 - and
to the rear fog lamp through pins 3 and
10 of connector C in fusebox G1 (see
"Rear and Front Foglamps").
Through these signals the control unit
checks for a possible malfunction of a
single bulb or a failure in the power
supply to fuse . If an anomaly is
detected, the control unit sends a signal
to pin 3 of connector D of C16 and lights
up the relative warning lamp.
