Fail-safe Function

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 them that allow the automatic transmission to continue driving This causes a DTC to be stored and the D indicator to blink and/or the MIL to come on The transmission may not shift normally during fail-safe operation Do not run the test driving diagnosis when the MIL is ON, or the indicator is blinking
