Summary
Supersedes Technical Service Bulletin Group 46 number 12-26 dated October 23, 2012. The yellow warning for electromechanical parking park (EPB) appeared once in the instrument cluster. The warning turned off after the ignition was cycled, and there have not been additional occurrences. EPB function was not affected. The adaptive cruise control (ACC) was inoperative once, but it resumed proper operation after the ignition was cycled, and there have not been additional occurrences. DTCs are logged in the EPB control module. There is an issue with the software in the EPB control module that occurs one time. Because the issue only occurs once, replacing the control module could cause an additional occurrence.
