Normal Level
STEER POSITION A (S8)
Output of Home Sensor Prox. used by the STM to determine if the drive unit is CW 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.
Over metal= less than 1V Not over metal= 6.5V

DGND
DGND is the B– for the Steer Position Prox. switch (S8). It is connected through the STM via B– cable at the TPA.

BUS+
The wire that carries the positive component of the digital communications between the STM and the Guidance Manager. No usable information can be gained by measuring the voltage on this wire.
No useful voltages are measurable
