Overview:This code indicates an electrical failure of the relay used to inhibit the engine brake during shifts. Detection:Starting at key-on and throughout operation, the System Manager constantly measures this circuit. A failure mode of a short to battery, short to ground, or open circuit is detected. Fallback:There is no fallback mode with this fault. Required Tools:1) Basic Hand Tools2) Digital Volt/Ohm Meter3) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Relay coil open or shorted2) Damaged tower or OEM harness3) Malfunctioning system manager ECU Eaton Gen 1 (AutoShift) Fault Code: 17 PID: SID 237 FMI: 4 Start Enable Relay Coil Eaton Gen 1...

Overview:This code indicates the system manager has detected that the battery power supply is low. Detection:The fault is detected immediately after power-up. This fault causes the service lamp to flash, but cannot be retrieved via key clicks (because turning the ignition key off at this point results in an immediate shutdown). Fallback:This fault 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) Damaged tower or OEM harness4) Damaged transmission harness5) Malfunctioning power connect relay6) Malfunctioning system manager ECU Eaton Gen 1 (AutoShift) Fault...

Overview:This code indicates the AutoShift failed to receive information from the engine or the engine failed to properly respond to throttle control during a shift as commanded by the engine J- 1939 data link. Detection:75 seconds after key-on and throughout the operation, the System Manager constantly monitors the communication with the engine ECM. If a communication fault occurs for more than five seconds, fault code 35 is set. Fallback:If the fault occurs while moving, it causes a 1-speed fallback. Once vehicle has stopped, the starting gear and reverse can be engaged. If the failure occurs at system initialization, it causes...
