Fault codes
Bobcat fault codes
Bobcat loaders show a service code on the instrument panel when a controller sees a reading outside its normal range: machine codes look like M0309 and engine codes like E000097-31. On M-Series loaders with the standard panel, press the Information button until the service code screen appears; deluxe and touch displays list codes under active warnings or service codes. Codes use a zero, not the letter O (MO309 is M0309), and the same number can mean different things on a loader and an excavator.
