Overview:This code indicates the Transmission ECU has detected low battery power supply to the electric shifter motors. Detection:Starting at key on and throughout operation, the Transmission ECU constantly measures the motor voltage. If the reading is low, the fault code is set. Fallback:This causes an In Place fallback. Required Tools:1) Basic Hand Tools2) Digital Volt/Ohm Meter3) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Battery bus fuse/circuit breaker is open2) Low batteries3) Corroded or loose contacts4) Failed power interface module5) Malfunctioning transmission ECU Eaton Gen 1 (AutoShift) Fault Code: 63 PID: SID 40 FMI: 6 Gear Select Motor Eaton Gen 1 (AutoShift) Fault...

Overview:This code indicates the transmission was unable to move the front box to neutral, during a shift request. Detection:The transmission detects this by attempting the same shifter actions five times and not sensing the desired position. Fallback:This causes an In Place Fallback. Required Tools:1) Basic Hand Tools2) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Low power to gear select motor2) Failed gear select sensor3) Malfunctioning electric shifter4) Malfunctioning yoke/clutch/mainshaft5) Failed shift block6) Failed or misaligned shift block7) Electric shifter calibration8) Dragging clutch9) Torque locked in gear Eaton Gen 1 (AutoShift) Fault Code: 65 PID: SID 251 FMI: 4 Low Motor Voltage Eaton...

Overview:This code indicates the transmission is unable to select the required rail during a shift. Detection:The transmission detects this by attempting the same shifter actions five times and not sensing the desired position. Fallback:This causes an In Place fallback. Required Tools:1) Basic Hand Tools2) Digital Volt/Ohm Meter3) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Low power to rail motor2) Failed rail select motor3) Failed rail select sensor4) Failed or misaligned shift block5) Malfunctioning transmission ECU Eaton Gen 1 (AutoShift) Fault Code: 71 PID: SID 60 FMI: 7 Stuck Engaged Eaton Gen 1 (AutoShift) Fault Code: 65 PID: SID 251 FMI: 4 Low...

Overview:This code indicates the transmission is unable to engage the desired gear in the front box during a shift. Detection:The transmission detects this by attempting the same shifter actions five times and not sensing the desired position. Fallback:This causes an In Place fallback. Required Tools:1) Basic Hand Tools2) Digital Volt/Ohm Meter3) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Malfunctioning electric shifter2) Malfunctioning yoke/clutch/mainshaft3) Failed shift block4) Failed or misaligned shift block5) Electric shifter calibration6) Failed gear select sensor Eaton Gen 1 (AutoShift) Fault Code: 72 PID: SID 59 FMI: 7 Failed To Select Rail Eaton Gen 1 (AutoShift) Fault Code: 71 PID:...

Overview:This code indicates the system was unable to bring input shaft to a stop using the interia brake. Detection:The System Manager monitors engine rpm before initial gear engagement. If the inertia brake is commanded on and the engine rpm does not drop below the acceptable limit this code will be set. FallbackThere is no fallback mode for this fault. Required Tools:1) Basic Hand Tools2) Hand-Held Diagnostic Tool3) 0-100 PSI Air Pressure Gauges4) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Low air pressure2) Contaminated air supply3) Clutch out of adjustment4) Damaged input shaft brake5) Malfunctioning inertia brake6) Damaged internal transmission gearing Eaton Gen...
