HVAC Control Module
As the data shown in the following table are standard values of normal operation vehicle measured by SUZUKI scan tool, use them for reference. Even if a vehicle is in good condition, there may be cases where the measured values do not fall within the standard range depending on the condition. Therefore, judgment as abnormal should not be made by checking just with this data.
