JAKO SCAN is a diagnostic scanner which works on Japanese (Toyota, Honda, Nissan and Mitsubishi) and Korean (Hyundai and Kia) made vehicles. It performs the following functions: - Read Diagnostic Trouble Codes (DTC) - Erase DTC - Read Current Data stream - Activation Test (Unit Test) Unlike many other scanners, JAKO SCAN operates on an embedded operating system which uses internal Flash Memory instead of cartridges to store the car programs. This eliminates the hassle of changing and keeping a wide selection of program cartridges. The unit is power up through the Diagnostic Link Connector (DLC) most of the time but some older car models where there was no power supplied then it needs to be powered through the cigarette lighter adaptor which is provided.
