Circuit/System Testing

WARNING: This page is about a different car, the 2010 GMC Yukon, 2010 Chevrolet Tahoe, and 2010 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect for DTC P1AC6, P0335, or any communication DTCs.
  2. Program the PIM with the latest software version and recheck for DTCs.
    • If the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM.
