Customer Question

I am working on a cummins ism 350st engine #35189861. I can't run a manual regen becuase it says the brake or clutch is depressed. I went into the parameters to see which one it was and it shows both depressed. I have disconnected the switches, used a
jumper wire to bypass them, and they still show depressed. How do u go about troubleshooting this

Ok

Sorry for the delay ! Got tied up later at work ! Are your brake lights staying on ? This would tell us your brake pedal may be stuck from a seized pedal pivot . Try cleaning around the pedal with a blow gun and lubing the pivot and make sure you pull up on the pedal .

Brake lights are not on.
Expert:  Andy replied 2 years ago.
