DDEC ENGINE TROUBLESHOOTING
Troubleshooting the DDEC engine and related systems is preformed by locating the malfunction within the trouble-
shooting symptom index (WP 0005 00), then referring to WP 0006 00 or WP 0007 00 for the required test or inspection
steps. The troubleshooting table in WP 0006 00 contains general procedures to identify and correct an engine or engine
related malfunction. The table also references the use of Check Engine Lights (CEL) and Stop Engine Lights (SEL)
flash codes to identify a problem. The information to utilize a Diagnostic Data Reader is also provided to aid in identify-
ing a malfunction.
Also available to troubleshoot the DDEC engine is The Detroit Diesel Data Link diagnostic CD Rom, used with a PC or
the SPORT computer.
