Mode | Symptom | Possible Cause |
[Mode 1] Forced engine shutdown | ● Engine stop | ● ETC system can’t proceed reliable algorithm procedure - Fatal ECM 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 | ● No response for accelerator activation ● Forced idle state | ● 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 ● Driver perceives lack of engine power. ● MIL ON (Normalvehicle running) | ● Not reliable accelerator position signal or bad maximum power generation - Faulty APS, ignition voltage or internal controller |
[Mode 6] Normal | ● Normal |
