Eaton Gen 2 (AutoShift) Fault Code: 11 PID: SID 254 FMI: 12 Shift Controller

Overview:
Fault Code 11 indicates an internal failure of the Shift Controller.

Detection:
The Shift Controller checks the program memory every time the key is turned on. If the Shift Controller detects a failure within the program memory, it sets this fault code.

Fallback:
This fault causes an in-place fallback while operating and a self-check failure if it occurs during power up.

Possible Causes:
1) Improper configuration software
2) Shift Controller

Shop Talk:
Key on. If the fault is present, the system should automatically detect the problem and set the code. If the fault is not present at key on, operate the vehicle and attempt to duplicate the driving conditions that triggered the fault code. Possible triggers include heat and vibration.

Eaton Gen 2 (AutoShift) Fault Code: 17 PID: SID 237 FMI: 3 Start Enable Relay Coil

Overview:
Fault Code 17 indicates an electrical failure of the relay that allows the engine to start after start-up conditions are met.

Detection:
Starting at key on and throughout operation, the Shift Controller
constantly measures the circuit. If a condition of short to battery, short to ground or open circuit is detected, Fault Code 17 is set.

Fallback:
The Start Enable Relay has no fallback; however, if the failure occurred before the engine was started, it is possible the engine will not start.

Possible Causes:
1) Relay Coil Open
2) Vehicle Harness
3) Shift Controller
4) Operator too quick on key (not waiting for a “N”)

Eaton Gen 2 (AutoShift) Fault Code: 26 PID: SID 55 FMI: 10 Clutch Slip

Overview:
Fault Code 26 indicates the clutch is not performing as expected. The Transmission Controller detected excessive clutch slip.

Detection:
When the transmission is in gear and the clutch is fully engaged, engine speed and Input Shaft speed are compared. If the engine speed is significantly different from the Input Shaft speed for a period of 1 second, the Fault Code is set.

Fallback:
This fault causes a down-shift fallback. Once the vehicle is stopped, starting gear and reverse gear can be engaged. The fault will clear at power down and up shifts will be allowed until the fault is detected again.

Possible Causes:
1) Worn or broken clutch

Shop Talk:
Operate the vehicle under load in highest gear possible with engine speed above 1500 RPM. At a steady speed, quickly and fully press the throttle. The failure is detected when clutch slip occurs.

Eaton Gen 2 (AutoShift) Fault Code: 27 PID: SID 55 FMI: 7 Clutch Disengagement

Overview:
Fault Code 27 indicates the clutch has not disengaged as expected.

Detection:
1) Starting at key on and throughout operation, the Shift Controller
constantly measures engine RPM and idle torque from the engine.
2) When engaging a start gear, if the engine speed falls significantly
below idle or engine torque rises significantly above idle torque the fault is set.
3) If in gear and the vehicle is brought to a stop and engine speed falls significantly below idle, the fault is set.

Fallback:
There is no fallback associated with this failure; however, it may be difficult to achieve gear engagement or disengagement

Possible Causes:
1) Worn or broken clutch

Shop Talk:
Operate the vehicle. If the fault is present, the system should automatically detect the problem and set the code. If the fault is not present, operate the vehicle and attempt to duplicate the driving conditions that triggered the fault code. Possible triggers include heat, vibration and aggressive stops.
