Fail-safe Mode
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
1.
Engine power varies with accelerator position, but driver perceives lack of engine power.
2.
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
