Fault Code 58 troubleshooting contents
The document is organised as a set of numbered fault isolation steps, each with a stated purpose and a clear go-to branch that sends the technician to the next step, a repair or the final verification. The main sections cover:
- Recording fault codes and identifying the FMI (2, 5, 6, 8 or 10)
- Using PD Mode to find intermittent Output Shaft Speed Sensor wiring faults
- Checking Output Shaft End Yoke tightness and the Tone Wheel
- Inspecting the auxiliary case and Auxiliary Output Bearing
- Verifying the 5-volt reference at the Output Shaft Speed Sensor
- Checking sensor-circuit continuity and ground and verifying the repair
Applicable truck models
This Eaton fault isolation procedure applies to trucks fitted with the Fuller Advantage Heavy Duty automated manual transmission, its Transmission Electronic Control Unit (TECU) and Output Shaft Speed Sensor. Every step is performed with ServiceRanger, the Eaton diagnostic software, and cross-referenced to the wider TRTS0980 Fault Isolation Procedures manual. Manufacturer background and current service literature are published on Eaton’s official transmission website.
Who needs the Fault Code 58 troubleshooting manual
Technicians investigating a lost output-speed signal or a speedometer complaint use this Eaton procedure to separate a worn Output Yoke, a damaged Tone Wheel and a wiring fault before condemning the sensor.
Because it is drawn straight from Eaton document TRTS0980, the page gives shop staff the same decision trees, connector pin references and pass-or-fail values the manufacturer uses, which shortens diagnosis time and supports accurate warranty documentation.
