Prerequisite for activation The ISG system operates in the following situations. The driver's seatbelt is fastened The driver's door and hood are closed The brake vacuum pressure is adequate The battery sensor is activated and the battery is sufficiently charged Outside temperature is not too low or too high The vehicle is driven over a constant speed and stops The climate control system satisfies the conditions The vehicle is sufficiently warmed up The incline is gradual The steering wheel is turned less than 180 degrees and then the vehicle stops Information If the ISG light (white) is turned on on the instrument cluster and does not meet the ISG system operating conditions, the ISG system is not activated.
The ISG system may not operate: When there is a malfunction with the ISG sensors or the ISG system. The followings occur, when there is a malfunction with the ISG system: The auto stop indicator ( ) will illuminate in yellow on the instrument cluster.
Description and operation DescriptionThe evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator from freezing by excessive cooling. The evaporator temperature sensor has the Negative Temperature Coefficient (NTC).
TroubleshootingDiagnosis with Diagnostic tool1.In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool).The diagnostic system (Diagnostic tool) provides the following information.1)Fault Code Searching : Checking failure and code number (DTC)2)Data Analysis : Checking the system input/
