Starting the Engine for the First Time

Starting the Engine for the First Time - Gen 5 DD15 Ops - #7628

To start the engine, the transmission should be in neutral and the ignition key turned to the ON position.

At the start of every ignition cycle, the instrument panel indicator lights will come on. This is the result of the electronic engine control system, called Detroit Diesel Electronic Control® (DDEC®), diagnosing the system to ensure everything is functional, including the cluster for the warning indicators. If no faults are detected, all indicators will go out in approximately five seconds.

The warning indicators must go out before starting the engine. If the warning indicators stay on, or do not come on momentarily after turning on the ignition, contact an authorized Detroit™ service outlet. Operating the engine under these circumstances may result in engine damage.
