Overview:The Fuller Advantage transmission is equipped with an Electronic Clutch Actuator (ECA) Speed Sensor that provides a secondary engine speed signal to the Transmission Electronic Control Unit (TECU). The ECA Speed Sensor is installed in the clutch housing. The ECA broadcasts the ECA Speed Sensor signal to the TECU through the High Integrity Link (HIL) contained within the transmission harness. The TECU uses the ECA Speed Sensor signal to determine engine speed when the J1939 engine speed signal is not available. Early models have a thread-in ECA Speed Sensor installed in the flywheel housing. Fault Code 65 indicates either a...

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 66 indicates battery power to the ECA is outside of the acceptable ECA operating range. 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...
