(1) Will read "Drive" if O/D is canceled
  1. TR___V is the voltage at the PCM pin 64 (TR3A Circuit) to signal return.
  2. "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.
  3. TR___D: 1= Open digital TR switch, 0= Closed digital TR switch.
  4. EEC-V Control System Breakout Box Readings: Taken from PCM signal pins for TR1, TR2, TR3A, TR4 to signal return.
    • Voltages 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.
