Allison WTEC II Fault Code: 44 PID: SPN: 12 FMI: Short-to-ground, A solenoid circuit
Main code 44 indicates the ECU has detected a short-to-ground in a solenoid or its wiring. The DO NOT SHIFT response is activated when this code is detected and all solenoids are turned off. Neutral start is inoperable.
If solenoid resistance is about 1?2 Ohms, a short-to-ground code may not be set but could cause a burned-out solenoid driver in the ECU. Replace the solenoid when this occurs (see appropriate transmission Service Manual for replacement procedure). If the solenoid driver is burned out, 69 XX codes will be set. See the troubleshooting procedure for 69 XX codes.
