| I was getting my new to me 2623vt ready last night and I am running it on a 9120. The tool came with accu-depth so I installed the harness on the tractor so I could use it. I plugged it in last night and I get the hydraulic light flashing and SCU 99 code whenever the tool is plugged in. The book says a failed calibration, can anyone point me in a direction as to what to look for? I have checked harness and sensor connections and they look clean and tight. Tia | |
