Fault Code 19 troubleshooting is the eight-page fault-isolation procedure for an ECA power or communication problem on the Eaton Fuller Advantage Heavy Duty transmission. This section of publication TRTS0980 identifies whether a Gen1 or Gen2 Electronic Clutch Actuator is fitted, checks for a failed software download, then verifies the 3-Way and 8-Way ECA connectors, ignition voltage and High Integrity Link continuity. Every measurement carries a specified range so the fault is isolated methodically.

Applicable truck models covered
The procedure applies to heavy-duty trucks with the Eaton Fuller Advantage or Fuller Advantage Heavy Duty automated transmission and either a Gen1 or Gen2 ECA. It references the 3-Way ECA Connector, the 8-Way ECA Connector, the 40-amp fuse and the 2-Way terminating resistor, all needing the OEM chassis wiring diagrams. Transmission specifications are published on the manufacturer’s official Eaton transmissions website.
Who needs this Fault Code 19 troubleshooting manual
Driveline technicians use this procedure after an ECA software update fails or a clutch actuator stops responding, to confirm ignition voltage, HIL positive and negative continuity and terminating-resistor values before replacing the ECA or transmission harness.
