WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- With a scan tool, recalibrate the BPP, clear all DTCs, and operate the vehicle within the Conditions for Running the DTC.
- If DTC P0573 resets as current, test the stop lamp switch signal circuit for an open or short to voltage.
- If circuits test OK, replace the ECM.
