Troubleshooting Section

An input is available to the ECM for connecting a

switch to shut down the engine while the engine

is operating in PTO mode. To use this feature,

the parameter "PTO Configuration" must be

programmed to "Cab Switches", "Remote Switches",

or "Remote Throttle". The following conditions must

also be met in order to use this feature.

"PTO Engine Shutdown Switch" must be

programmed to "P1/J1:7" or "P1/J1J1:23".

The PTO On/Off Switch is in the ON position and

the PTO is active.

PTO Engine Shutdown Switch is in the ON

position.

186-04 PTO Engine Shutdown Short Circuit is

not active.

The vehicle speed is equal to zero.

No vehicle speed faults are active.

If the vehicle speed is not equal to zero, or if there

are active vehicle speed faults, the engine will go

to low idle. The engine will not shut down when

the vehicle speed falls to zero. When the PTO

Engine Shutdown Switch is pressed, a 186-14 PTO

Shutdown Switch Occurance will become active.

The code will stay active until the engine shuts

down. When the engine shuts down, the code will

be logged.

connected to P1/J1:7 Input # 4. The parameter "PTO

Engine Shutdown Switch" must be programmed to

"P1/J1:7".
