Torque Monitoring



Torque Monitoring

Description
The Engine Torque control is monitored to ensure that there is no large unintended Torque greater than requested by the driver. This monitor consists of an independent engine Torque measurement and engine speed monitor in idle speed control.





If the above table does not include details of the following enabling conditions: - IAT, ECT, vehicle speed range, and time after engine start-up then the state of these parameters has no influence upon the execution of the monitor.
