Circuit/System Verification

WARNING: This page is about a different car, the 2008 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
  • Repair any brake system related symptoms and DTCs before performing this diagnostic.
  • Electromagnetic interference (EMI) on the speed sensor signal circuit may cause erratic cruise control operation.

Engine ON, while rotating the steering wheel to both steering stops, observe the scan tool Cruise Control Switch parameter while pressing each of the cruise control switches. The parameter should toggle between On, Off, Resume, Set, and Cancel as the applicable switch is pressed.
