DTC 3E3-04-ECU internal failure - Rail pressure plausibility
Control Module : ECU
Context:
The Engine Control Unit (ECU) A-9000 monitors fuel pressure in the common rail. This monitoring is performed using
two software levels of monitoring because fuel pressure monitoring is a critical functionality. If the ECU A-9000 sees
an error in the level two monitoring but not in level one monitoring, this fault will occur.
Solution:
1. Check the ECU A-9000 for the appropriate software and re-flash, if necessary.
A. If the fault has been resolved, return the machine to service.
B. If the fault has not been resolved, escalate an ASIST concern.
