View faults

Review prioritized, secondary, and unprioritized engine faults and open available diagnostic information.

Expected result

The current fault status, details, and available snapshot or FIS information are visible for the connected engine.

Important notes / prerequisites

Connect to and identify the correct engine before opening Faults. Fault analysis and Fault Information System content require internet connectivity.

Understanding fault information

A fault code identifies a malfunction or abnormal condition detected by the controller. Review the fault information to understand the reported condition and choose the next troubleshooting action.

DTK groups faults as Primary, Related, and Unprioritized to help you organize the investigation. Review the available Fault Details and fault-specific troubleshooting information before deciding on a repair.

Windows procedure

Open Faults from the engine Device Dashboard.
Review the Primary, Related, and Unprioritized fault groups.
Select an individual Cummins fault code to open Fault Details and the snapshot, when supported.
Select the underlined fault code number on the left side of the screen to open the applicable Fault Information System file in a web browser.
Use the fault information to guide troubleshooting and the next diagnostic action.

Fault categories

Primary faults: Critical faults that should be repaired first.
Related or secondary faults: Faults that may be resolved when the primary fault is corrected.
Unprioritized faults: Faults that do not have the same primary-fault priority.

Fault Details, snapshots, and FIS

Select a Cummins fault code entry to open Fault Details and its snapshot, when supported. A fault snapshot contains parameter values captured in association with the fault. Use the available values as context for the reported condition.

Select the underlined fault code number to open the corresponding Fault Information System (FIS) information in a web browser. Use the fault-specific guidance to plan troubleshooting. Internet access is required. See View FIS.

Common problems

If fault data is missing, confirm the connection and verify that the correct engine is selected. If FIS content does not open, check internet connectivity.

DTK Mobile differences

From the ECM Device Dashboard, select Faults to open Faults and Analysis. The same Primary, Related, and Unprioritized groups, Fault Details, supported snapshots, and FIS workflow apply to DTK Mobile. Internet access is required for Faults and Analysis and FIS.
