Fail-Safe Mode

FAIL-SAFE MODE REFERENCE CHART

Mode	Description	Symptom	Possible Cause
MODE 1	FORCED ENGINE SHUTDOWN	Engine stop	ETC system can't proceed reliable algorithm procedure Fatal PCM internal programming error Faulty intake system or throttle body
MODE 2	FORCED IDLE & POWER MANAGEMENT	Forced idle state controlled by fuel quantity regulation and ignition timing adjustment	ETC system can't control engine power via throttle device Disabled throttle control or broken throttle position information
MODE 3	FORCED IDLE	Forced idle state and no response for accelerator activation	No information about the accelerator position Broken APS 1 and 2, faulty A/D converter or internal controller
MODE 4	LIMIT PERFORMANCE & POWER MANAGEMENT	Engine power is determined by accelerator position and idle power requirement (Limited vehicle running)	ETC system can't securely control engine power
MODE 5	LIMIT PERFORMANCE	Engine power varies with accelerator position, but driver perceives lack of engine power. MIL ON (Normal vehicle running)	Not reliable accelerator position signal or bad maximum power generation Faulty APS, ignition voltage or internal controller
MODE 6	NORMAL	Normal
