According to NASASpaceflight.com article from December 4, 2013, yes:
Another element that will heading uphill on EFT-1 will be an inert
Launch Abort System (LAS).
Most of the LAS won’t be active for the flight – not least because
there will be no humans on board the Orion.
However, the jettison motor will be active, allowing for a separation
testing during the ascent phase. As such, this will be a nominal
detachment of the LAS when it is no longer required during the flight
into space, as opposed to an actual abort test.
“The LAS will be the first actively controlled launch escape system
ever flown, and it incorporates a throttleable solid-rocket motor for
attitude control, a novel reverse-thrust abort motor, advanced solid
propellants, and lightweight composite materials in the abort motor
case and fairing,” noted LAS project manager for NASA, Kevin Rivers.
The first ascent abort test of the LAS is scheduled for around 2019,
after the uncrewed Exploration Mission -1 (EM-1), but in plenty of
time ahead of the first crewed mission where it will be required,
namely Exploration Mission -2 (EM-2).
Other sources confirm this, for example the Universe Today article on NASA Pressing Towards Fall 2014 Orion Test Flight – Service Module Complete from January 22, 2014.
