Fail-safe Function
WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
When an abnormality occurs in the signal from a sensor, a switch, a solenoid valve, or from another control unit, the PCM ignores that signal and substitutes a pre-programmed value for that signal allows the automatic transmission to continue operation. This causes a Confirmed DTC to be stored and the D indicator to blink and/or the MIL to come on. The transmission may not shift normally driving fail-safe operation. Do not run the test-driving diagnosis when the MIL is ON, or the D indicator is blinking.
