Issue
In the driver assistance system of heavy-duty trucks, the vehicle control ECU contains an incorrect program that prevents braking force from being maintained when the Driver Emergency Driving Stop System (EDSS) activates and brings the vehicle to a stop. If the system activates and the vehicle stops on a slope or incline, the vehicle may begin to roll.
Corrective action
On all vehicles, reprogram the vehicle control ECU with the corrected/updated software.
