VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. A WIRE THAT CONNECTS THE ENGINE CONTROL MODULE (ECU) TO THE AUTOMATIC BRAKING CONTROL SYSTEM (ABS) CONTROLLER IS MISSING. THE ENGINE BRAKE CAN LOCK UP THE REAR AXLE WHEELS ON A SLICK PAVEMENT, AND THE ABS WOULD NOT PREVENT THE LOCK UP.
IF THE WHEELS LOCKED UP, THE POTENTIAL FOR A VEHICLE CRASH COULD OCCUR.
DEALERS WILL INSTALL THE MISSING WIRING CIRCUIT ON THE ABS BRAKES.
