Eaton Fuller Advantage (2017) Fault Code: 96 PID: SPN: TBH FMI: 3 ECA Battery Voltage Gen2 ECA: Voltage Above Normal or Shorted High

Overview:
The Fuller Advantage transmission is equipped with an Electric Clutch Actuator (ECA) that controls the position of the clutch assembly. The ECA operates on a non-switched battery power supply.Fault Code 96 indicates battery power to the ECA is outside of the acceptable ECA operating range, but is specific to systems that use a Gen2 ECA. Troubleshooting for this procedure is specific to the Gen2 ECA and associated harnesses.

Note: The troubleshooting procedure for Fault Code 66 may direct users to use this troubleshooting procedure if the vehicle is equipped with a Gen2 ECA, even if Fault Code 96 was not set by the transmission. This is because some transmission software versions do not set Fault Code 96.

Detection:
ECA monitors the battery voltage supply it receives. If the supplied voltage falls below operating range or spikes significantly above operating range, the ECA will broadcast a fault condition to the TECU, which sets the fault code Active.

Conditions to Set Fault Code Active:
FMI 3 Voltage Above Normal or Shorted High: ECA battery voltage rises above 34 volts for 2 seconds or longer

Fallback:
All FMIs
F flashes in gear display.
Service light flashes (if equipped).
Engine does crank and/or start.
Transmission does not engage a gear from neutral.
When the transmission is in gear, it will not allow up shifts.
ECA may maintain the current clutch position using the clutch holding device.
ECA may move the clutch to the closed position (clutch engaged against engine flywheel).

Conditions to Set Fault Code Inactive:
FMI 3: ECA battery voltage drops below 32 volts for 6 seconds.

Possible Causes:
FMI 3
1) Starting/Charging System
- Alternator/Generator failure
- Improper vehicle jump-start
