a Will read DRIVE if O/D is canceled.
A. TR_V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
B. "In Between" reading could be caused by a shift cable or digital TR sensor misaligned or a digital TR sensor circuit failure of TR1, TR2, TR3A, or TR4.
C. TR_D:1 = Open Digital TR switch, 0=Closed Digital TR switch.
D. Breakout Box Readings: Taken from PCM signal pins for TR I, TR2, TR3A, TR4 to signal return.
Voltages for TR1, TR2, TR4:
-0 = 0.0 volts (circuit shorted to ground).
-1= 9.0 - 14.0 volts (open circuit).
-Voltage for TR3A:
-0 = 0.0 volts (circuit shorted to ground).
-1= 1.3-1.8 volts (open circuit).
-1.8-5.0 volts = Invalid reading (open in wires or bad resistor in digital TR sensor).
