System Revisions

The 2005 MTC system remains mostly carryover from 2004. Revisions to the 2005 MTC system include:

• a new telltale in the instrument cluster for RG vehicles equipped with a Cabin Heater. The telltale illuminates when the Cabin Heater is operational. Messages bussed from the MTC Module tell the instrument cluster when to illuminate the telltale and when to shut it off.
