Here’s a breakdown of the key aspects of this fault code:
1. Diagnostic Software and Tools: The fault is diagnosed using the INSITE 8.9.2 Engine Diagnostic Software in conjunction with the Cummings INLINE 6 Diagnostic Adapter.
2. Circuit Description: The ECM has built-in diagnostics that continuously monitor the internal memory for errors.
3. Component Location: ECMs are located on both banks of the engine.
4. Diagnostic Conditions: The diagnostic for this fault code is active when the keyswitch is in the ON position and runs continuously.
5. Fault Code Setting Conditions: The fault code is set when the ECM detects a read or write error within its internal components.
6. Actions When Fault Code is Active: Upon detection of the fault, the ECM will activate the red STOP ENGINE lamp.
7. Clearing the Fault Code: To reset the fault code, turn off the keyswitch and allow the ECM to power down completely before turning the keyswitch back on. The fault code status changes to INACTIVE after the diagnostic runs successfully without detecting any errors. The red STOP ENGINE lamp turns off once the diagnostic passes. Active and inactive faults can also be cleared using the “Reset All Faults” command in the recommended electronic service tool.
