Previous calibrations resulted in an immediate limp-in mode condition when a DTC is sensed during Key ON, and the vehicle speed is below 45 mph.
This calibration always sets a DTC as soon as an electrical, mechanical or hydraulic problem is identified. But the transaxle may not go into limp-in mode until the problem happens several times in a given key start or after several key starts while identifying the DTC in Park or Neutral before vehicle operation begins.
