Active Codes Test; Final Test - Detroit Diesel Series 60 EGR Technician Manual

Active Codes Test

Perform the following steps to test for active codes.
1. Turn ignition ON.
2. Connect either a DDDL or a DDR reader.
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 V Single ECU Troubleshooting Guide, (6SE565) 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 ECU 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 ECU to protect other engine components.
5. If the issue is not related to the EGR system components, or if technical support is
required, contact the Detroit Diesel Customer Support Center at 313-592-5800.
6. Perform a Final Test.

Final Test

Follow these steps for a final test:
1. Reconnect all disconnected sensors and wiring harnesses and assemble all disassembled
components.
2. Start and run the engine.
3. Perform a road test to try and duplicate the original complaint.
[a] If original symptoms and codes are not detected, repairs are complete.
[b] If any original codes are detected, review this section again and contact the Detroit
Diesel Customer Support Center at 313-592-5800.
