Explorer 4WD V6-4.0L (2009)
allows the powertrain control strategy to optimize fuel control and transmission shift schedules while delivering the requested wheel torque.
The ETC monitor system is distributed across two processors within the PCM: the main powertrain control processor unit (CPU) and a separate
monitoring processor. The primary monitoring function is carried out by the independent plausibility check (IPC) software, which resides on the main
processor. It is responsible for determining the driver-demanded torque and comparing it to an estimate of the actual torque delivered. If the generated
torque exceeds driver demand by a specified amount, appropriate corrective action is taken.
ETC System With A 3-Track APP Sensor Failure Mode And Effects Management:
a - ETC illuminates or displays a message on the message center immediately; MIL illuminates after 2 driving cycles
