Door Lock System
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
The system has a pair of circuits between door lock actuators and the MICU to improve safety of the system. One is for driver's side door lock actuators, and another is for front passenger's side door lock actuators. Each circuit has two fuses, and even if one of the fuses is blown, at least the driver's side, or the front passenger's side actuators continue to work normally. When one fuse is blown, another fuse in the same circuit must be checked (for example, when the under-dash fuse/relay box No. 35 fuse is blown, the No. 49 fuse also must be checked).
