The Cluster Ionizer makes a disinfection and decomposition of a bad smell from the air-conditioner or inflow air. And it cleans inside air of a vehicle.
When running an air-conditioner or heater, it starts with "CLEAN MODE" on it and repeats from "CLEAN MODE" to "ION MODE" and from "ION MODE" to "CLEAN MODE" every 15 minutes.
In the CLEAN MODE, the cluster ionizer generates negative ions and positive ions and makes a disinfection and decomposition of a bad smell from the air-conditioner or an inflow air. The cluster ionizer has functions as follows; a deodorization effect, a disinfection effect, and an air-cleaning effect.
It has an operation indicator lamp on the upper side of its display area and shows whether it is operaing or not.
In the ION MODE, the cluster ionizer generates negative ions and cleans inside air of a vehicle.It has an opeation indicator lamp on the lower side of its display area and shows whether if is operating or not.
If the voltage of the cluster ionizer's diagnosis line is lower than 1.5V, the air-control module sets DTC B1688.
