Request Switch.
Active codes will be flashed on the RSL (Stop Engine) first, followed by inactive
codes being flashed on the AWL (Check Engine). The codes will continue to flash
and repeat as long as the Diagnostic Request Switch is held in the ON position.
Both CPC and MCM faults are included.
Active Codes
The active codes will be flashed on the RSL (Stop Engine) in the order of most
recent to least recent occurrence based on engine hours.

Detroit Diesel Electronic Control System Features

The electronic engine control system offers a variety of features and options
designed to warn the operator of any engine or Aftertreatment System (ATS)
malfunction. Options can range from warning panel lights to automatic reduction in
engine power followed by automatic engine shutdown. The electronic engine
control system has the ability to perform diagnostics for self-checks and
continuous monitoring of other system components.
Depending on the application, the electronic engine control system can monitor oil
temperature, coolant temperature, oil pressure, fuel pressure, coolant level and
remote sensors (if used).
The electronic engine control system activates the Amber Warning Lamp (AWL) /
Check Engine and the Red Stop Lamp (RSL) / Stop Engine to provide a visual
warning of a system malfunction.
Data Recording Capability
The electronic engine control system contains the ability to extract detailed data on
engine use and performance using DDEC Reports software. This detailed data (or
DDEC Data) is stored in the CPC and contains information on engine performance
such as fuel economy, idle time, and time in top gear. Critical incidents such as
detailed diagnostic data records and hard braking events are also stored. DDEC
Data can be downloaded using DDEC Reports software to produce reports.
NOTE: As the diagnostic and reprogramming software applications have
evolved, the requirements for additional computer storage capacity and
memory has increased. Please review these computer specifications
carefully and take any necessary steps to update your hardware as needed.
