Inside the Eaton Fault Code 11
- Record fault codes, FMIs, occurrences and timestamps
- If the code sets active or inactive, replace the TECU
- Clear codes with ServiceRanger and test drive
- Verify repair (Step V)
- Contact Eaton at (800) 826-4357 for further diagnostics
This is a short, decisive procedure. After recording the transmission codes, FMIs, occurrences and timestamps from the Service Activity Report, the reader is told that if the code sets either active or inactive the correct action is to replace the control unit, then proceed to the verify-repair step. Verification means reconnecting all connectors, confirming components are properly installed, clearing codes with ServiceRanger and road-testing the vehicle to try to reproduce the complaint. If no code sets and the truck operates properly the test is complete; if the code returns during the drive, the manual directs the technician to contact Eaton at (800) 826-4357 for further diagnostics, and any other code is routed through the Fault Code Isolation Procedure Index on page 14.
Applicable truck models
The step applies to Fuller Advantage transmissions built around the Transmission Electronic Control Unit and diagnosed with ServiceRanger. It cross-references the Fault Code Isolation Procedure Index on page 14 for any code other than 11. Verify coverage against your VIN and build sheet on the Eaton Vehicle Group site.
