System Operation Description:Use this procedure if either of the following diagnostic codes are indicated:
30-8 PTO Throttle Signal Invalid (29)
30-13 PTO Throttle Out Of Calibration (29)Also, use this procedure if the remote accelerator position sensor is suspected of improper operation.Remote Accelerator Position SensorA remote accelerator position sensor may be used for PTO purposes. The remote accelerator position sensor must be connected to J1/P1-31 Auxiliary Input 3. Before the ECM will respond to the remote accelerator position sensor, the ECM "PTO Configuration" must be programmed to "Remote Throttle".The remote accelerator position sensor is used to provide a throttle position signal to the ECM. Sensor output is a constant frequency signal with a pulse width that varies with the pedal position. This output signal is referred to as either a duty cycle or a pulse width modulated signal (PWM) and this output signal is expressed as a percentage between 3 and 100 percent.

Schematic for PTO configuration "Remote Throttle"Test Step 1. Inspect the Electrical Connectors and the Wiring
Connect Caaterpillar Electronic Technician (ET) to the service tool connector. Verify that the parameter for the PTO configuration is programmed to the "Remote Throttle".
Thoroughly inspect ECM vehicle harness connector J1/P1, the firewall bulkhead connector and the connector for the remote accelerator position sensor. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the remote accelerator position sensor:
J1/P1-31
J1/P1-30
Check the allen head screws for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque value.
Check the harness and wiring for abrasion and for pinch points from the remote accelerator position sensor to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following diagnostic procedure:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the Cat ET to the data link connector.
Turn the keyswitch to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check and record active diagnostic codes.Note: When the ECM automatically calibrates new duty cycle values for the low idle throttle position and for the high idle throttle position the ECM assumes 22 percent duty cycle at low idle and 75 percent duty cycle at high idle. As a result, you may notice that the status of the "PTO Throttle Position" reaches 100 percent well before the PTO accelerator is fully depressed. This is normal. After some cycling of the accelerator pedal to the high idle position, the ECM will adjust the calibration automatically. The ECM will adjust the calibration automatically provided that the high idle stop position is within the
