Circuit/System Verification

WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that DTC C0277, C0297, or B3445 is not set.
  2. Ignition ON, observe the scan tool BPP parameter while applying and releasing the brake pedal. The reading should change between Applied and Released.
    • If the parameter does not change between applied and release, replace the BPMV and verify DTC does not reset. If DTC reset, replace the EBCM.
