Test Description
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.
The number below refers to the step number on the diagnostic table.
- 2. If the system does close properly, then suspect either the sunroof limit switch soft stop signal circuit or the sunroof limit switch low reference circuit for a poor connection or intermittent.
