RING-SEAL 1390567 - Caterpillar

Which Generate This Code:The "PTO Configuration" is a Customer Parameter. The "PTO Configuration" is programmed to "Remote Throttle". The ECM is not receiving a correct signal for the PTO Accelerator.Note: If the "PTO Configuration" is programmed to "Remote Throttle", the ECM must receive a proper signal from the remote accelerator position sensor at all times. The remote throttle signal must be present even when the PTO ON/OFF switch is in the OFF position.System Response:Electronic System Response The ECM returns the engine to low idle when the problem is detected.Service Tool Display or Lamps Caterpillar Electronic Technician (ET) will display "0%" and "DIAG" next to "Throttle Position" on the status screen while the diagnostic code is active.Engine Response The engine will remain at low idle while the diagnostic code is active.The diagnostic code is probably caused by an open circuit in the signal circuit for the accelerator pedal position or an open circuit in the 12 volt sensor supply voltage circuit. An abnormal change in the signal frequency can also cause this code.Test Step 1. Perform the following test: Remote PTO Accelerator Position Sensor Circuit - TestResults:
OK - Stop.
