Symptom:
P1793-TRD LINK COMMUNICATION ERROR
When Monitored and Set Condition:
P1793-TRD LINK COMMUNICATION ERROR
When Monitored: The transmission controller pulses the 12 volt TRD signal from the
PCM to ground, during torque managed shifts with the throttle angle above 54 degrees.
The TRD system is also tested whenever the vehicle is stopped and the engine speed is at
idle.
Set Condition: This code is set when the Transmission Control Module (TCM) sends two
subsequent torque reduction messages to the Powertrain Control Module (PCM) via the
TRD link circuit and does not receive a confirmation from the PCM over the communica-
tion bus.

1NOTE: Low fluid level can be the cause of many Transmission problems. If
the fluid level is low locate and repair the leak then check and adjust the
fluid level per the Service Information.
