1. DTC P0602 is stored in the TCM history.
2. The TCM does not illuminate the CHECK TRANS light (non-OBD II strategy).
3. The TCM returns to the boot program, and then waits to be recalibrated.

5. DTC is stored in the TCM history.
CONDITIONS FOR CLEARING THE DTC:
TCM must be recalibrated with a valid VEPS calibration.
