Ignore the previous advice as it is nonsense.
Of those 3 codes, only the first one has anything to do with the operation of the vehicle. The second 2 are EVAP emission codes. The P1698 indicates that the PCM is losing communication with the TCM which probably means the TCM is going bad but could be a wiring issue also.
