Eaton Gen 1 (AutoShift) Fault Code: 35 PID: SID 231 FMI: 2 Engine Control Failure
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 an AutoSelect fallback mode.
Required Tools:
1) Basic Hand Tools
2) Hand-Held Diagnostic Tool
3) Digital Volt/Ohm Meter
4) AutoSelect/AutoShift Troubleshooting Guide
5) Data Link Tester
Possible Causes:
1) Faulty J-1939 data link
2) Faulty vehicle interface harness or connections
3) Faulty engine harness or connections
4) Excessive radio interference
5) Faulty engine ECM
6) Faulty engine fuel pump
