Summary
Some customers may experience that the air conditioning system stops working. Upon inspection, DTC B1082:19 [DASH_ESU] (Air mix actuator (RH) circuit malfunction) is stored in memory. DTC B1082:19 is stored as a past malfunction and continues in one drive cycle, then returns normal at the next drive cycle. Due to the electrical noise caused when the air mix actuator is driven too quickly, a false malfunction may be detected. To eliminate this concern, the control software of the dash-electrical supply unit has been modified.
