The switch
H35
sends the signal for
activating the rear fog lamps to the check device inside the rev
counter
E15
(pin 1 of connector
B
).
The supply for the check device inside
E15
arrives
directly from the battery (maxifuse
J/B2
of
B99
) at
pins 10 and 16 of connector A, through fuses
F2
and
F3
of
the junction unit
B1
; the former protects the circuits for
the lights on the left hand side, the latter those on the right.
the former protects the circuits for the lights on the left hand
side, the latter those on the right.
The check device only controls (pin 4 and
pin 17 of connector A) the supply of the rear fog lamps in the centre
rear light clusters on the left
F35
and the right
F36
if
one of the two go ahead signals arrives from the dipped beam headlamps
or the front ghts.
The first signal arrives from the dipped
beam headlamps circuit at pin 8 of connector A (
See E2011 DIPPED HEADLAMPS
).
The second signal is supplied by the circuit
inside the module
E15
: it is the same signal which lights
up the "front fog lights on" warning light.
At the same time as the lights are switched
on, the "rear fog lamps on" warning light - inside
E15
-
is also switched on with pin 14 of connector A providing the earth.
In the case of failures in the circuit,
the "lights failure" warning light - inside
E15
-
comes on, with the supply controlled by the ignition (IINT), pin
15 of connector A, of the line protected by fuse
F4
of the
additional fuse box
B98
.
The switch
H35
is lit up when the
side lights are switched on by means of the line coming from the
switch for the steering column switch unit
H5
.
