Their location was designed to provide operators immediate feedback to prevent damage to the machine. Either operators or technicians can quickly address issues, reducing downtime and maintaining operational efficiency and support.  

Guide to locating error codes on some common models:  

R-Series Models 

Depending upon the machine and model, it may be equipped with a touchscreen or standard (non-touch) display screen. To access the “service codes” on these models, complete the following:  

• Touch Display: Touch the screen and choose “service codes”   
• Standard Display: Use the jog shuttle (knob) to navigate and select “service codes”  

M2-Series Models 

Depending upon the machine and model, it may be equipped with a deluxe panel or a standard instrumentation panel that features only gauges and a display. To access the “active warnings” on these models, complete the following:  

• Deluxe Panel: Use the jog shuttle (knob) to navigate and select “service codes”  
• Standard Instrumentation Panel: Press the information button to reach a screen that shows an open book symbol with a wrench overlay. This screen will show active error codes, and you can cycle through if there are multiple entries.  

Please refer to the Bobcat Service Codes and Deluxe Panels informational video to learn more about finding your service codes.  

Other Bobcat Machine Models  

Not all Bobcat machines and models may have a touchscreen or standard display for warning lights and symbols. Instead, traditional instrumentation panels may display errors, issues or warnings. Please consult the operator guide of your machine’s make and model to understand what each light and symbol means.
