P1df8 Jeep Description

The purpose of the diagnostic is to monitor if the Powertrain Control Module (PCM) executed the torque requested by the Transmission Control Module (TCM). This is determined by comparing the PCM's executed torque to the original torque requested by the TCM over the Controller Area Network (CAN) bus. These torque requests only occur during shift operations. This diagnostic checks for engine torque reduction too high.
