Threshold Value | Case1 |
•
Throttle position for the lower return spring check is not reached within a limit maximum time(Difference between throttle position and setpoint > 0.48%°) | |
Case2 |
•
When ETC power stage is off, Throttle can not return by spring power in the limp-home position within a limit maximum time(Difference between Throttle position and adapted voltage in limphome position >0.18 V) | ||
Case3 |
•
Throttle position for the upper return spring check is not reached within a limit maximum time(Difference between throttle position and setpoint >0.48%) | ||
Case4 |
•
When ETC power stage is off, Throttle cannot return by spring power in the limp-home position within a limit maximum time(Difference between Throttle position and adapted voltage in limphome position >0.18 V) | ||
Case5 |
•
Throttle flap cannot reach the setpoint within the hysteresis within a limit maximum time(Difference between throttle position and requested position >0.48%) | ||
Case6 |
•
When ETC power stage is off, Throttle cannot return by spring power in the limp-home position within a limit maximum time(Difference between Throttle position and adapted voltage in limphome position >0.18V) | ||
Diagnostic Time |
•
0.8~1.2 sec. | ||
Limp-Home |
•
Forced limited RPM mode : The PCM/ECM limits engine speed to 1500rpm
•
Electrical check of the ETC system is prohibited | ||
MIL On Condition |
•
Immediate | ||
