Without the HDS (use only if HDS is not available)
WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
The self-diagnostic function of the driving position memory system detects system problems. If a system problem is detected, the buzzer built into the power seat control unit sounds for 5 seconds. This information can be retrieved through the driving position memory switch indicators.
