C15 – 0030-08 PTO Throttle signal invalid (29)

Conditions Which Generate This Code:

The ECM detects the following conditions:
• The “PTO Configuration” is programmed to “Remote Throttle”.
• The ECM is not receiving a valid signal from the PTO throttle.
• The ECM has been powered for at least three seconds.

Note: If the “PTO Configuration” is programmed to “Remote Throttle”, the ECM must receive a proper
signal from the remote throttle at all times. The remote throttle signal must be present even when the PTO ON/OFF switch is in the OFF position.

System Response:
The ECM returns the engine to low idle when the problem is detected. “DIAG” will be displayed next to the status for “Throttle Position” on the electronic service tool.

Possible Performance Effect:
The engine will remain at low idle while the diagnostic code is active.


Perform the following diagnostic procedure:
“Remote PTO Accelerator Position Sensor Circuit – Test”

• OK – STOP.
