# Service bulletin 07\-002\-24a

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's 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.
