M1A1 tank DSESTS software

PS: The Preventive Maintenance Monthly, Dec, 2005

Have you had DSPS 32.1 software loaded on your Direct Support Electrical Systems Test Set (DSESTS) with a Combined Support Function Module (CSFM)? Without it, you won't be able to check the tank commander's panel (TCP), PN 12549797-3, on tanks that have had MWO 9-2350-264-50-12 applied. A faulty TCP won't alert the commander when the NBC system overheats or is clogged.

Nor will it automatically shut down the NBC system to avoid a possible fire.
