Detroit Diesel MBE EGR Technicians's Manual The most essential tool to properly diagnose and troubleshoot an MBE EGR engine is the Detroit Diesel Diagnostic Link® (DDDL). This tool will provide all the help needed as it contains proper troubleshooting information for all products.
Detroit Diesel MBE EGR Technicians's Guide This section provides tips on troubleshooting complaints of low power, excessive oil consumption, exhaust smoke, coolant loss, and intermittent concerns. The following lists of questions are only guidelines. The service outlet need not consider every question to resolve the complaint. The questions to consider should depend upon the circumstances surrounding the vehicle symptoms. The technician should ask the operator questions for these seven basic concerns. They are Low Power, Fuel System, Air System, Oil Consumption, Exhaust Smoke, Coolant Loss, and Intermittent Concerns.
NOTE:
It is absolutely critical that you understand the EGR system to be qualified to offer any type of proper diagnostics. Do not waste time trying to troubleshoot a DDC product you are not qualified to troubleshoot. Your company may incur wasted labor hours. If you are qualified to perform a troubleshooting task and have spent more than one hour on that task, STOP, and contact the Detroit Diesel Customer Support Center at 313-592-5800. Once you have discussed your options with a technical support person, you can perform the required tests and evaluations. Please keep in contact with your technical support person. This allows you to stay on track.
