Example of Cat ET Error Code
Note: A common root cause of a failed "Hystat Pump and Motor Solenoid Calibration" is contamination of the solenoid(s), pump, or motor controller(s). Contamination will restrict motion and/or cause hysteresis and will prevent a steady gear ratio to be attained during calibration. If the calibration fails, do NOT adjust the "Min" or "Max" stops of the forward or reverse pumps. Refer to Table 2 for additional information of each error code.
Table 2
Cat ET Error Codes for Hystat Pump and Motor Solenoid Calibration
Error ID and Description Reasons for the Error Codes Possible Causes
"10D4 - Left Pump Minimum Current Out of Range Low "
"10DA - Right Pump Minimum Current Out of Range Low" Pump starts to stroke or is always on stroke at a current outside the lower end of the calibration range. "Pump Null" adjustment may be off
Contamination in the pump control
Motor speed sensor is disconnected
Malfunctioning or sticking solenoid
"10D5 - Left Pump Minimum Current Out of Range High"
"10DB - Right Pump Minimum Current Out of Range High" Pump does not start to stroke at a current outside the upper end of the calibration range. "Pump Null" adjustment may be off
Contamination in pump control
Motor speed sensor is disconnected
Malfunctioning or sticking solenoid
"10D6 - Left Pump Maximum Current Out of Range Low"
"10DC - Right Pump Maximum Current Out of Range Low" Current is not detected when the pump reaches maximum displacement. This occurs because the pump does not destroke from the maximum displacement within the calibration range. Contamination in pump control
Sticking solenoid
"10E0 - Left Motor Minimum Current Out of Range Low"
"10E6 - Right Motor Minimum Current Out of
