When Monitored
- When Monitored for Signal Invalid or Missing
Ignition key is ON and the engine is not in cranking mode.
Power supply must be between 7 volts and 24 volts and the Main Micro Processor (MMP) supply diagnostics have not failed.
The Bus OFF failure is not present, the CAN communication between TCM and PCM is not lost, there are no dual port RAM faults and the CAN message was read at least once.
- When Monitored for Signal Not Rational - Engine Speed Check for Zero Value
Ignition key is ON, the engine is not in cranking mode, there is no shift in progress, a gear is engaged, the clutch speed is greater than a threshold 250 RPM.
Power supply must be between 7 volts and 24 volts and the Main micro processor (MMP) supply diagnostics are not in failure.
The clutch position sensor has no electrical faults and the clutch speed has no rationality faults.
The Bus OFF failure is not present, the CAN communication between TCM and PCM is not lost, there are no dual port RAM faults and the CAN message was read at least once.
- When Monitored for Signal Not Rational - Engine Speed Compared to Odd or Even Clutch Speed and Odd or Even Input Shaft Speed
Ignition key is ON, the engine ignition status is on, the engine is not in cranking mode, there is no shift in progress, the engine torque is less than 100 Nm or the clutch temperature is less than 170 °C, a gear is engaged and the clutch speed is stable for more than 1 sec.
Power supply must be between 7 volts and 24 volts and the Main micro processor (MMP) supply diagnostics are not in failure.
The driveline speed signal has no faults.
The Bus OFF failure is not present, the CAN communication between TCM and PCM is not lost, there are no dual port RAM faults and the CAN message was read at least once.
