new GCS controls do show fault codes with letter and number. example: G021. these are the generic codes that are shown without using a pass through tool. with a pass through they will show the regular 4 digit fault number.
What is a pass through tool? I just had a G021 fault, drive shutdown POR required, and I can’t find any info on that particular fault. Reset it and it runs fine. I guess time will tell if it returns...
