Check For Active Codes; Verification - Detroit Diesel Series 60 EGR Technician Manual

Check for Active Codes

Check for active codes as follows:
1. Turn ignition ON.
2. Plug in DDDL or a DDR.
3. Read active codes.
4. Record or print codes. Ensure that PID, SID, and FMI are recorded. Refer to the proper
code section of the DDEC III/IV Single ECM Troubleshooting Guide, (6SE497) to
troubleshoot that code.
NOTE:
FMIs listed as 14 are diagnostic information codes and no troubleshooting is required.
For example, an engine derates due to high TCO temperature; a 404/14 code will be
stored. This would indicate that conditions warranted having the ECM derate the fueling
to the engine. If the customer complaint was a power loss, it could be explained that loss
of power was done by the ECM to protect other engine components.
5. If the issue is not related to the EGR system components, or if assistance is needed, contact
Detroit Diesel Customer Support Center at 313-592-5800.
Verification
Follow these steps to test:
1. Reassemble connectors or components.
2. Start and run the engine.
3. Perform a road test if this is necessary to duplicate original complaint.
[a] If symptoms/codes are gone, repairs are complete.
[b] If any codes display, review this section again; contact Detroit Diesel Customer
Support Center at 313-592-5800.
