The Engine Control Module (ECM) detects the following conditions:
•The duty cycle of the signal for the PTO throttle is less than 5 percent or more than 95 percent for more than two seconds.
•The PTO Configuration is programmed to “Remote Throttle”.
•The ECM has been powered for at least three seconds.
Probable Causes:
1) ECM Connection/Harness
2) Accelerator Position Sensor
3) Accelerator Position Sensor Harness
4) ECM Failure
