It is important to note that these are just some of the error codes that can occur on CAT forklift trucks. The specific error codes that will appear will vary depending on the model of the forklift and the specific problem that is occurring. If you are experiencing an error code on your forklift, it is important to consult the owner's manual or contact a qualified technician for assistance.
