iS Module Installation
The installation is the reverse of the removal pro-
cedure.
iS BUTTON
iS Button Overview
The iS button contain a series of 4 diodes for the
UP and DOWN arrow switches.
The center wire to the switches (pin C), is com-
mon for iS button and VTS button. The other two
wires (pins A and B), act as signal wires for each
set of switches to the gauge. They actually each
form one branch of an electronic circuit within the
gauge.
Each diode (in circuit) drops a nominal 0.6 Vdc
when conducting electricity. If the circuit current
passes through all four diodes (if the iS switch
is open), a drop of 2.4 Vdc would be measured
across the 4 the diodes (pin B to pin C). This
2.4 Vdc at pin B tells the gauge the iS switch is
open.
If the iS UP switch is pressed, 2 diodes are by-
passed. The remaining two diodes in the circuit
drop 1.2 Vdc (at pin B).
If the iS DOWN switch is pressed, 1 diode is by-
passed. The remaining three diodes in the circuit
drop 1.8 Vdc (at pin B).
The gauge senses these voltages through pin 14
of its connector, and interprets them as signals
that tell it which switch is activated.
If the command generated by the closure of a
switch concerns the iS module, a circuit within
the gauge will translate it to CAN protocol and
