I have IGBT module BSM15GD60DLC. It is installed in 3-phase VSD and I suspect that one output phase is faulty.
Does anyone has data sheet?
Is it possible to test this module with multimeter?

The BSM15GD60 data sheet can be downloaded from:
http://www.datasheetcatalog.com/datasheets_pdf/B/S/M/1/BSM15GD60DN2.shtml

As far as in-circuit testing of IGBT is concerned, you will be able to test for shorts and free-wheel diodes ..
For a proper test you will have to remove module from the circuit and test each IGBT using the following procedure:
Testing IGBT
Basic testing IGBTs (Insulated Gate Bipolar Transistors) should be similar to an enhancement mode N-channel MOSFET except that the threshold voltage may be larger than a typical MOSFET (e.g., 8 V instead of 4 V).

Check for shorts with an ohmmeter.
Put a current limited supply across C-E with an ammeter in series.
Apply at least 10 V G-E. The transistor should turn on.
Ground the gate. The transistor should turn off.
