Automatic Shutoff Problem

06-03-2003, 05:28 PM

'95 Regency, Cummins 300 and have a Kysor-Cadillac panel with auto shut off for three systems in case of malfunction. However, it looks like the panel is not working properly and it shuts off the engine while driving down the road at 65+ mph. Anyone know of source for replacement or tech help? Thought it was fuel problem but Cummins in Bakersfield, CA says engine and fuel OK.
Thanks!

I think you are talking about an L-10 motor. I believe the platform is the Celect. The motor is designed to shut down or derate for the following 6 items.
1)low oil psi. 2)high coolant temp. 3)high boost air temp 4)high oil temp 5)Low coolant level 6)Very low oil psi.

Trouble codes ...
low oil psi is 143
high coolant temp 151
high boost air temp 155
high oil temp 214
low coolant level 235
very low oil psi 415

If you can read the flash codes this will help. They will flash on the engine protection light.

Turn the ignition switch on but do not start or crank over - the check engine light and shutdown lights should come on and then go off � press the engine diagnostic switch and hold it. The �check engine� & �stop engine� lights will flash the active error code. As follows - The yellow �check engine� light will flash once then the red �stop engine� light will flash out the error code. For error code (low oil psi) 143, the �check engine� light will flash 1 time followed by the �stop engine� light flashing - FLASH (1 second pause) FLASH FLASH FLASH FLASH (1 second pause) FLASH FLASH FLASH - then the �check engine� light will flash once and repeat all over again. To see if there is more than one active trouble code press the idle up/resume switch to go to the next active code. If you turn your key on and no lights come on then you lost your wiring to the ECM.

If you were driving down the road and it shuts off on you - do not turn the key off - attempt to read the trouble codes before attempting a restart.

I hope this helps.
