Fault Code 17 troubleshooting is the nine-page fault-isolation procedure for the start-enable relay circuit on the Eaton Fuller Advantage Heavy Duty transmission. This section of publication TRTS0980 sorts the fault by FMI, verifies the configured start-enable type, tests relay voltage and resistance for 12 and 24 volt systems, and checks the circuit wiring for shorts to power and ground. The lettered steps end in a controlled crank test so the repair is proven.

Applicable truck models covered
The procedure applies to Eaton Fuller Advantage and Fuller Advantage Heavy Duty automated transmissions on chassis using a physical start-enable relay wired by the OEM. It references the 5-Way relay socket, the 38-Way Vehicle Harness pins 4, 26 and 32 and both 12 and 24 volt resistance ranges, so OEM schematics are needed. Transmission data is published on the manufacturer’s official Eaton transmissions website.
Who needs this Fault Code 17 troubleshooting manual
Truck electricians chasing a no-crank or unwanted-crank complaint use this procedure to confirm relay latching voltage, coil resistance and circuit continuity, and to prove the transmission can interrupt cranking before replacing the relay or TECU.
