WARNING: This page is about a different car, the 2011 Honda CR-V, 2010 Honda CR-V, 2009 Honda CR-V, 2008 Honda CR-V, and 2007 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.
When any of the data from the B-CAN circuit cannot be received within a specified time, or an unusual combination of the data is recognized, the MICU defaults to its software fail-safe mode, and replaces the missing or unusual data with a pre-programmed value.
