Eaton Fuller Advantage (2017) Fault Code: 68 PID: SID 227 SPN: FMI: 14 Grade Sensor: Special Instructions
Posted by PerDiezel Solutions on
Overview:The Fuller Advantage is equipped with a Grade Sensor which calculates vehicle incline. The grade position is used for the Hill Start Aid (HSA) feature and provides information to assist in vehicle launch and shifting. The Grade Sensor is internal to the Transmission Electronic Control Unit (TECU). Fault Code 68 indicates an issue with either the Grade Sensor or the Grade Sensor calibration. Note: Initial calibration of the Grade Sensor must be completed at the OEM assembly plant or anytime the TECU is replaced in the field. See Grade Sensor Calibration procedure in TRSM0980. Detection:Starting at key on, the TECU...
Eaton Fuller Advantage (2017) Fault Code: 71 PID: SPN: 560 FMI: 7 Unable to Disengage Gear: Mechanical System Not Responding
Posted by PerDiezel Solutions on
Overview:The Fuller Advantage transmission uses the X-Y Shifter to engage and disengage a gear based on the driver’s selected mode of operation. Gear disengagement is achieved by activating the X-Y Shifter Gear Motor, which controls the fore-and-aft movement of the Shift Finger. Pushing the Shift Finger against one of the Shift Bar Housing Shift Blocks guides the Shift Yoke to disengage the Sliding Clutch from a gear. The position of the X-Y Shift Finger is monitored by the Transmission Electronic Control Unit (TECU) by way of the X-Y Gear Position Sensor and Rail Position Sensor. Fault Code 71 is set...

Eaton Fuller Advantage (2017) Fault Code: 72 PID: SPN: 772 FMI: 7 Failed to Select Rail: Mechanical System Not Responding
Posted by PerDiezel Solutions on
Overview:The Fuller Advantage transmission uses the X-Y Shifter to engage and disengage a gear based on the driver’s selected mode of operation. Rail selection is achieved by activating the X-Y Shifter Rail Motor, which controls the lateral movement of the X-Y Shift Finger within the Shift Bar Housing. Certain shifts require the transmission to engage a different rail on the Shift Bar Housing. These rail shifts require the X-Y Shifter to move to Neutral prior to selecting another rail and allowing the next gear engagement. The Shift Bar Housing Interlock physically prevents the engagement of two gears at the same...
