Circuit/System Verification

WARNING: This page is about a different car, the 2008 Saturn Outlook, 2008 GMC Acadia, and 2008 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Verify that B3794 is not set as current or history before performing this diagnostic. If B3794 is set as current or history, go to DTC B3794 .
  1. Engine ON, observe the scan tool Cruise Control Switch parameter in the BCM while pressing the cruise control switch ON and OFF. The reading should change between ON and OFF.
    • If the parameter does not switch between ON and OFF, replace the BCM.
  2. Engine ON, test drive the vehicle and attempt to engage cruise. Verify that cruise control engages properly and that DTC P0575 is only set as a history code.
    • If cruise control does not engage and the DTC P0575 sets as current, replace the ECM.
  3. If the cruise control system tests normal, clear all codes. The vehicle is OK, do not replace the ECM or BCM.
