320GC caterpillar excavator. After replace solenoid proportional for stick out, bucket close, and left travel forward. I need to do calibration 1. pump pressure & 2. Implement with pressure pump For pump pressure calibration has been successfully calibrated. but for implement calibration it always fails and error code 12A0 appears: stick unload minimum current out of range high. I followed the instructions in the error code to replace the stick unload solenoid. but error code 12A0 persists and implement calibration fails again.
