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,orTR4.
C. TR_D: 1= Open Digital TR switch, 0=Closed Digital TR Switch.
D. Breakout Box Readings: Taken from PCM signal pins for TR1,TR2,TR3,TR4 to signal return.
^Voltage for TR1,TR2,TR4:
^0=0.0 volts.
^1=9.0-14.0 volts.
^Voltage for TR3A:
^0=0.0 volts.
^1=1.3-1.8 volts.
^1.8-5.0 volts=Invalid reading (Open in wires or bad resistor in digital TR Sensor).
