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 is fully engaged by pushing the harness connector toward the damper. If an audible click is heard, or substantial engagement travel is noted, ensure the remaining damper connectors are fully engaged as well.
When the scan tool is used to clear the DTC, the ESCM ignition cycle counter is disabled for the remainder of the ignition cycle. This allows the DTC to set upon initial malfunction detection. Once the ignition is cycled, the counter resets to 3.
The scan tool can be used to command the suspect damper ON and OFF while actuating the suspension and noticing an increase and decrease in damping control.
