High Integrity Link is Eaton Fault Code 16, the loss of the proprietary CAN data link that connects the TECU, Electronic Clutch Actuator and, if fitted, the Push Button Shift Control device on a Fuller Advantage Heavy Duty transmission. This five-page section of publication TRTS0980 defines the SPN 625 FMI 2 condition, explains the five-second detection window, lists the many wiring and connector causes and shows the component layout. It is the definition companion to the Fault Code 16 troubleshooting steps.

This definition covers Eaton Fuller Advantage and Fuller Advantage Heavy Duty automated transmissions with an Electronic Clutch Actuator and, if equipped, an Eaton PBSC. The link runs through the transmission harness to the ECA and the vehicle harness to the PBSC, with a terminating resistor, all following OEM routing. Transmission data is published on the manufacturer’s official Eaton transmissions website.
Who needs this High Integrity Link manual
Driveline technicians tracing lost communication between the TECU, ECA and shift control use this Integrity Link page to understand the wiring, terminating resistor and connector causes before starting the continuity tests. The long causes list spans the harnesses, connectors, terminating resistor, batteries and both power supplies, which is why the companion troubleshooting page needs eleven pages to isolate the break.
The complete PDF, published under Eaton document TRTS0980, is available in the DiagTechPro manuals library; a free account is required to download it.
