Scion IGI relay freezing

Some 2005-2008 tC and 2008-2009 xD and xB Scion vehicles may exhibit a condition with multiple warning lights illuminated, vehicle not shifting from Park to Drive, and/or other accessories becoming inoperative after the vehicle has cold-soaked in sub-freezing ambient air temperatures (below 14 degrees F).

A newly designed IG1 relay has been made available to address this concern.
