Supplies working voltage to the Steer
Position Prox when is present on
the STM.
If
not present, check voltage at
STM and see
if
is lit.
Output of Home Sensor Prox used by the
ESM
to determine
if
the drive unit is C W
or CCW of center. When over metal
(CW), the switch is closed and the output
is low. When not over metal (CCW), the
switch is open and the output is hi.
DGND is the B- for the Steer Position Prox
switch. It is connected through the STM.
Not connected to any circuitry on the
STM.
The
B-
for the Steer Controller. It is
connected through the STM.
The wire that carries the positive
component of the digital communications
between the STM and the Wire Guidance
manager. N o usable information can be
gained by measuring the voltage on this
wire.
The wire that carries the negative
component of the digital communications
between the STM and the Wire Guidance
manager. N o usable information can be
gained by measuring the voltage on this
wire.
