When Monitored: When the ignition is turned from the "off" position to the "run" position and/or the ignition is turned from the "crank" position to the "run" position.
Set Condition: This DTC is set if the Transmission Control Module (TCM) senses voltage on any of the pressure switch inputs prior to the TCM energizing the relay. Note: Due to the integration of the Powertrain and Transmission Control Modules, the transmission part of the PCM has its own specific power and ground circuits.
