Overview:The Fuller Advantage transmission is equipped with a Low Capacity Inertia Brake (LCIB) to slow Input Shaft speed for more efficient gear engagement. As the Electronic Clutch Actuator (ECA) pulls the Heavy-Duty ECA Clutch Release Bearing back against the LCIB, the friction plates contained within the LCIB make contact with the outer plates and slow the Input Shaft down to allow smoother gear engagement. Fault Code 45 indicates the LCIB failed to reduce Input Shaft speed. Detection:The Transmission Electronic Control Unit (TECU) commands the ECA to open the clutch and contact the LCIB. If the TECU does not see a...

Overview:The Fuller Advantage X-Y Shifter is equipped with a Rail Position Sensor. The X-Y Rail Position Sensor reports lateral movement of the Shift Finger to the Transmission Electronic Control Unit (TECU) as a voltage signal. The X-Y Rail Position Sensor is connected to the TECU via the Transmission Harness. The TECU performs continuous diagnostics on the circuit to detect a shorted circuit, open circuit or incorrect position reading. Fault Code 51 is set when the TECU has detected either an electrical failure of the X-Y Rail Position Sensor circuit or a mechanical failure within the X Y Shifter. Detection:The TECU...
