Allison WTEC II Fault Code: 44 PID: SPN: 12 FMI...

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...

Allison WTEC II Fault Code: 43 PID: SPN: 26 FMI...

Main code 43 indicates the ECU has detected an open solenoid low side driver (switch) or a low side (ground) solenoid wire shorted-to-ground. An open or short prevents the ECU...
