The U1600 code is a Diagnostic Trouble Code (DTC) that sets when the Adaptive Cruise Control (ACC) module is reprogrammed with a corrupted flash file or if the reprogramming is interrupted before completion.

When the ACC module detects this fault code, it disables the ACC system and displays a message in the Electronic Vehicle Information Center (EVIC) indicating that the Adaptive Cruise Control has been disabled. The ACC system will return to normal operation once the DTC goes to stored, and the DTC will be cleared after a 100 consecutive ignition cycles with no active detection. The U1600 code is related to ECU Application Software Mismatch.
