Hi everyone,

Received Code 0286. Says something to do with PTO deceleration switch. Not sure how to troubleshoot and fix? Truck shut down for a split second and started on its own again.

Thank you,

Derek

I doubt that fault 0286 alone is going to cause intermittent shut-off... but one never knows.

Go to the multiplexing screen to see what the 0286 is all about.

Also why so many tranny codes?.

Based on the screen shot I'd say you have a wiring issue. Abnormal update rate, abnormal update rate, abnormal update rate, data erratic, abnormal update rate. Either a bad ground somewhere, a loose or damaged wire, tarnished fuses or maybe lost a terminating resistor? Probably start by pulling up the wiring diagram on quickserve and see if there's a common element with all those faults. Also easy to check the battery connections, wires, crimps and vehicle grounds before digging deeper.
