Circuit/System Verification

IMPORTANT: Repair any brake system related symptoms and DTCs before performing this diagnostic.
  1. Rotate the steering wheel to both steering stops while activating each cruise control switch separately. With a scan tool, observe all cruise control switch parameters in the ECM. Ensure that each cruise control switch activated and that each displayed switch position parameters do not match or reads Error, as the steering wheel is turned.
    • If the parameters match with each depressed switch accordingly, go to Diagnostic Aids .
