Voltages for TR1, TR2, TR4:
0=0.0Volts.
1= 9.0-14.0 volts.
Voltage for TR3A:
0 = 0.0 volts.
1 = 1.3-1.8 volts.

Wiggle Test Information For Open/Shorts

TR4, TR3A, TR2 and TR1 are all closed in PARK. PARK is a good position to check for intermittent open circuits (with scan tool monitoring TR__D).
TR4, TR3A, TR2 and TR1 are all open in OVERDRIVE, so OVERDRIVE is a good position to check for shorts to ground. To determine the shorted components while observing TR__D, unplug the TR and see if the short goes away. If the short is still present unplug the transaxle harness and see if the short goes away. If the short is still present, then the short is in the PCM or vehicle harness. Remove the suspect circuit(s) wire terminal from the PCM connector. If the short is still present, then the PCM has an internal failure, otherwise the failure is in the vehicle harness.
