Overview:Fault Code 25 indicates the TECU has determined that all transmission functions are operating normally and the transmission currently has no logged fault codes. Detection:Fault Code 25 is a TECU self-check and should be present when no other fault codes have been logged. This condition is normal and means that there are no failed circuits or components. Fault Code 25 will not display when verifying fault codes with ServiceRanger, but may appear when using the key-clicks method to verify fault codes. Conditions to Set Fault Code Active:FMI 1 – Data Valid But Below Normal: All systems report no fault codes....

Overview:The Fuller Advantage Transmission is equipped with a Heavy Duty Electronic Clutch Actuator (ECA) Clutch. The Transmission Electronic Control Unit (TECU) monitors engine speed and Input Shaft Speed Sensor values to calculate clutch slip. Fault Code 26 indicates that a clutch slip event has occurred. Detection:The TECU calculates a significant variance between the engine speed and Input Shaft Speed Sensor values. Conditions to Set Fault Code Active:FMI 10 – Abnormal Rate of Change: The TECU monitors and compares both Input Shaft Speed and engine speed. If the TECU calculates that engine speed is greater than Input Shaft Speed by over...

Overview:The Fuller Advantage Transmission receives torque input through the clutch. The amount of torque being transferred through the clutch is controlled by the Electronic Clutch Actuator (ECA), which moves the Clutch Yoke, thereby opening and closing the clutch. The Transmission Electronic Control Unit (TECU) monitors engine speed and Input Shaft speed to determine proper clutch operation. The TECU sends requests to the ECA to open or close the clutch during vehicle operation. If the ECA position is below the required value or the Input Shaft speed indicates a lack of separation from engine speed with the clutch commanded open, the...
