Diagnostic Aids
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
Before proceeding with the diagnostics, ensure the electrical harness connector at the suspect damper or sensor is fully engaged by pushing the harness connector toward the damper or sensor. If an audible click is heard, or substantial engagement travel is noted, ensure the remaining damper and sensor connectors are fully engaged as well.
