C0545: Electronic Stability Control Inhibit
11 vehicles · 7 makes · $250-$3,500 repair
Most Reported On
C0545 is an OBD-II diagnostic trouble code meaning “Electronic Stability Control Inhibit.” This chassis/brake code indicates the electronic stability control (ESC) system has been inhibited, meaning it has temporarily disabled itself because of a related fault or invalid condition. Stability control helps keep the vehicle from skidding by selectively braking wheels and managing engine power, and it relies on inputs like wheel speed, steering angle, and yaw sensors. When one of those inputs is missing or implausible, the system shuts itself off and sets this code. Often it is a secondary code triggered by another underlying fault rather than a problem with stability control hardware itself. This code is most commonly reported on 2005-2010 Chevrolet Cobalt, 2006-2011 Chevrolet HHR, and 2014-2017 Chevrolet SS, plus 8 other vehicles, with repair costs ranging from $250 to $3,500.
