Upon receiving clearance from Dallas Clearance; the crew loaded the SID for the JPOOL6 Departure from DAL in the Collins FMS. The clearance given was 'cleared to [destination] via JPOOL6 ACT As Filed; Climb 4000 Expect 6000; Departure Freq 124.3 [and a squawk]'. The flight crew briefed the SID per the Jeppesen Chart prior to Takeoff from 31R. Dallas Love tower...cleared [us] for takeoff RW31R' without any additional heading or instruction. Upon takeoff climb; the autopilot was selected above 700ft AGL and began a left turn to intercept a course to TTT VOR. Upon noticing the error; the captain disconnected the autopilot simultaneously while being queried by Departure Control about the clearance. Departure then issued a heading of 150 degrees which was complied with immediately. Upon further examination on the ground [at our destination]; the FMS is not correctly loading the JPOOL6 departure and commanded an erroneous course to the autopilot and flight director upon selection.
The reporter advised he had programmed and flown the JPOOL SID on a number of previous occasions without problems. This was his first use since the latest chart and database revision. The crew had briefed the departure and were anticipating flying the initial charted headings '310 to 5.5 DME' thence 'hdg 010.' Instead TTT immediately became an active waypoint and when the autopilot was engaged it attempted to turn direct TTT.
A CL30 flight crew cleared to depart DAL on the JPOOL SID off Runway 31R was surprised when the autopilot attempted to turn left direct to TTT vice fly the charted 'headings for vectors' northeast of TTT.
