Thousands of bobcats are being retired after decades of devoted service. This might turn out to be the most crucial “fault code” you’ve ever needed since not only do you run the risk of running out of bobcats when you need them, but you might not even be able to identify the issue. After all, bobcat systems are an entirely different animal than those seen in other cars.
The bobcat’s error codes are listed below along with brief descriptions of each one. “Diagnostic Trouble Codes (DTCs)” are another name for the fault codes provided. Only informational in nature, this list. It does not take the place of the necessity for a skilled Bobcat mechanic to diagnose broken Bobcat equipment.
