ABS CAN Message is Eaton Fault Code 22, set when the TECU loses J1939 contact with the ABS module or is told Hill Start Aid is unavailable on a Fuller Advantage Heavy Duty transmission. This two-page section of publication TRTS0980 explains how Hill Start Aid holds the foundation brakes for three seconds on grades of one percent or more, defines the SPN 563 FMI 9 and FMI 14 conditions, and lists the ABS and HSA Disable Switch causes. It underpins any lost Hill Start Aid complaint.

Applicable truck models covered
This definition covers Eaton Fuller Advantage and Fuller Advantage Heavy Duty automated transmissions with Hill Start Aid, on any chassis OEM whose ABS module communicates over the J1939 data link. Component identification refers back to OEM guidelines because the ABS wiring is proprietary. Transmission data is published on the manufacturer’s official Eaton transmissions website.
Who needs this ABS CAN Message manual
Fleet technicians investigating an inoperative Hill Start Aid use this CAN Message page to confirm J1939 communication with the ABS module and correct HSA configuration before returning to OEM guidelines. Because the fault can mean either a lost link or a deliberate not-available message, the page separates the two FMIs so a technician knows whether to chase wiring or an ABS configuration issue.
