This is what I managed to get from our database.

Failure Conditions
1. ECM will set DTC P1401 and illuminate MIL if a DM- TL system malfunction is detected.
2. ECM will set DTC P1402 and illuminate MIL if a DM- TL over-pressure motor malfunction is detected.
3. ECM will set DTC P1403 and illuminate MIL if a DM- TL change- over valve malfunction is detected.

Testing for P1401, P1402 or P1403 not available from manufacturer.

P1623 = Diagnostic Lamp Power Stage Malfunction. ( This code is supposedly only for Sonata 2.5 L only)
