How to troubleshoot Detroit Diesel Series 60 DDEC V?
If codes were logged, troubleshoot the codes as necessary. If no codes were logged (besides Code 39), proceed to step 4 . Inspect system for any air leaks in the exhaust, EGR, or intake system (including charge-air-cooler). If leaks were detected, repair as necessary. If no leaks are present, go to step 5 .
How to troubleshoot Flash code 61 Detroit Diesel?
The following procedure will troubleshoot Flash Code 61. Perform the following steps to test alternator ground. Disable the alternator by removing the alternator belt. Start and run the engine; warm to greater than 87°F (30°C). Does the code return?
What is the SPN code for a FMI Sid?
SPN FMI PID/SID PID/SID ID FLASH CODE FAULT DESCRIPTION 634 4 SID 40 1321 Constant Throttle Valve Circuit Failed Low 634 3 SID 40 1321 Constant Throttle Valve Circuit Failed High 634 5 SID 40 1321 Constant Throttle Valve Circuit Failed Open 636 1 SID 21 1235 Crankshaft Position Sensor Signal Voltage Too Low
How is resistance measured on DDEC V Series 60?
Once a good case ground is established, keep one of the measurement probes in place and move the other probe to one of the five exposed male injector terminals on the ECM/ECU. Measure the resistance. Repeat this procedure at each of the five terminals.
When to use Detroit Diesel engine protection code?
Engine Protection Codes — This code is activated when a engine operating condition exists that can cause immediate damage to the engine and the engine should be shut down until the condition is corrected to prevent additional damage. To read codes, use the Detroit Diesel Diagnostic Link (DDDL).
What to do if your DDEC V is not working?
If the voltage measurement are incorrect, and the wiring checks are okay, try a test ECM/ECU programmed for EGR, or contact the Detroit Diesel Customer Support Center (313–592–5800). Perform the following steps to check the EGR Valve. Disconnect the oil supply from the EGR valve actuator.
What does code 147 / 14 mean on a DDEC V?
Code s 147/14 — occurs if error in actual EGR rate vs desired EGR rate (Desired – Actual) during EGR mode operation. This FMI signifies low EGR flow. This fault will illuminate the CEL/AWL for the duration of the fault being active. Reassemble the engine.
Where is the harness on a DDEC truck?
The most likely location is the primary OEM wiring harness that links the DDEC’s engine controller to the connectors on the firewall. This harness supplies the input and output signals for both the Jake and the engine fan. This is the first harness that we needed to remove from the truck and inspect.
What are the fault codes for Detroit Diesel engines?
