Defect
The SSAM (Single Signal detect and Actuation Module) software was developed with insufficient consideration, causing the microcomputer inside the SSAM to repeatedly reset itself upon startup or during operation after incorrectly detecting an internal fault. As a result, the engine may fail to start, fail to restart, or fail to shut off, and electrical components may become inoperative or may activate involuntarily. (The SSAM is a body controller unit that integrates electrical component control and power distribution functions for the cab and body-mounted equipment.)
Corrective action
On all vehicles, reprogram the SSAM software with the corrected updated software.
