The hazard
On certain trucks with an ISX15 engine and a 1.9 M cab, the engine wiring harness is missing circuits to allow the illumination of Check (CEL) and Stop (SEL) Engine Lamps and sounding of the Stop Engine Alarm. A failure to notify the operator of a serious engine problem may result in an engine failure without warning, and loss of motive power while the vehicle is in motion, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will inspect and/or test the engine harness for the missing circuits, and if found missing, an overlay jumper harness will be installed.
