44. FUEL FILTER / WATER SEPARATOR
If the vehicle is switched to contact, a voltage is
applied through wire 1010 and fuse E170 both
to connection point 1 of the electronic unit
(D855) and to connection point 6 of the fuel
filter/water separator switch (C747). If the switch
is operated, relay G234 is activated through wire
5048. Now a voltage is also applied, through
wire 1000, fuse E171, wire 1179, contacts 3 and
1 of relay G234 and wire 5051, to connection
point rdzt1 of fuel filter/water separator sensor
(B241). If the heating element is switched on
with switch C747, the LED “ON” in the electronic
unit D855 will be lit.
If the sensor in the fuel filter/water separator
section detects water, the LED “DRAIN” in the
electronic unit (D855) is activated through wires
5049 and 5050.
