IF THE IGNITION IS TURNED ON AND THE FUSE FOR THE ELECTRONIC CONTROL MODULE (ECM) POWER FEED LINE IS REMOVED OR BURNED OUT, THE SAFETY FEATURES DESIGNED TO PREVENT INJURY TO PERSONS WORKING IN THE VICINITY OF THE ENGINE WILL BE BYPASSED, AND UNINTENTIONAL CRANKING OF THE ENGINE WILL OCCUR.
Risk
IF UNINTENTIONAL CRANKING OF THE ENGINE OCCURS, PERSONS WORKING IN THE VICINITY OF THE ENGINE COULD BE INJURED AND THE VEHICLE COULD MOVE.
What owners should do
DETROIT DIESEL DISTRIBUTORS WILL REWIRE THE VEHICLES USING A REVISED ECM WHICH WILL ELIMINATE UNINTENTIONAL CRANKING.
