Our 2004 Crossfire has been trouble free for about two years (20,000 mi).

About a month ago the BAS/ESP light came on intermittently. This happened about once a week. The cruise control also would not work. Now the Brake Lamps are on all the time. The iCarsoft meter reads "C1207 S9/1 Stop Lamp Switch A7/7b BAS Diaphram Travel Sensor Implausible Signal From Component."

Does anyone have a similar experience, or a suggested troubleshooting sequence for this problem?

Thank you
John
