Fail-safe function
WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
When a CPU problem or abnormal power supply voltage is detected, the MICU enters the hardware fail-safe mode, and each system output load is set to the pre-programmed fail-safe value.
