Eaton Fuller APMT-1234 Fault Code Charts
The Eaton Fuller APMT-1234 Fault Code Charts manual is designed as a quick-reference diagnostic resource for identifying electronic fault codes and their corresponding fault descriptions. The document is identified as APMT-1234, February 2004, and is presented under the Roadranger, Eaton Fuller and Dana branding.
The manual explains how to use MID, PID/SID and FMI numbers to locate the appropriate fault code. The introduction provides a clear workflow: first read the displayed fault information using a diagnostic tool, then use the MID and vehicle/system manufacturer to locate the appropriate chart, and finally use the PID/SID and FMI values to identify the corresponding fault code and description.

Comprehensive Fault Code Reference
The sample pages demonstrate fault-code charts for multiple vehicle systems and manufacturers. The contents include MID 128 engine fault information for CAT and Cummins, together with additional engine, transmission, braking, trailer ABS and VORAD fault-code sections referenced in the manual.
The CAT section includes fault information covering areas such as cylinder faults, throttle signals, oil pressure, boost pressure, intake manifold air temperature, coolant temperature, fuel temperature, engine overspeed, data-link faults and ECM-related faults. The Cummins section includes cylinder and injector faults, fuel supply and fuel control systems, engine timing, crankcase pressure, rack position, EGR systems and variable geometry turbocharger-related faults.
Organized Diagnostic Information
Fault information is arranged in a structured table containing PID/SID, FMI, Fault Code and Fault Description. This format makes it easier to cross-reference a displayed diagnostic code and identify the associated system or condition.
The contents page shown in the sample also references transmission fault-code charts for Eaton AC-AS1, AS2-ASX, ASW, CEEMAT, CEMT, DM2 and Lightning systems, along with Meritor FreedomLine and SureShift. Brake and ABS sections include Bendix, Eaton and Wabco systems, while trailer ABS sections include Bendix, Eaton, Haldex and Wabco.
Useful Workshop Reference
This manual is particularly useful as a workshop reference when diagnosing electronic faults on commercial vehicle systems. Its chart-based organization allows technicians to quickly move from the module identification to the relevant fault-code information.
Important: The manual itself advises users to verify the accuracy of fault codes with the individual OEMs. Always use appropriate service procedures and manufacturer information when performing diagnosis or repairs.
