    The VSI-2534 is a SAE J2534 interface that allows technicians to manage reprogramming activities on automotive vehicles from 1996 to current model years. This activity is typically accomplished by accessing OEM reprogramming sites to obtain detailed information for ECU reflashing.

    DG Assist

    Provides vehicle status reporting functionality along with unique features for Chrysler including VIN and SRI read/write capabilities.

    • VIN: Reads the VIN that is on the ECU. This can be used to verify the VIN number is correct to the VIN plate on the vehicle.
    • Current Calibration: Shows the current calibration on the ECU. This can be used to identify and confirm whether a newer/later update is available for the specific vehicle when compared to the new, available OEM calibration information.
    • DTC's: This area will provide a DTC Count, the specific DTC's that are stored and also give the ability to Clear DTC's. If a DTC is present, the MIL indicator will be illuminated in red. The DTC Definition link will take you to a spreadsheet to search for the definitions to those DTC's. Remember, in several cases, a successful reprogramming event may actually set a DTC, which must be cleared after completing the reprogramming event. Some OEM applications will also allow the clearing of DTC's as part of their process.
    • Get/Set Oil Life: For vehicles equipped with this feature, reading and writing new values is available upon the oil change.
    • Inspection / Maintenance: This feature will display the various IM monitors that are specific to the ECU/Vehicle the device is connected to. For the most accurate reading, the VSI-2534 should be connected directly to the vehicle.
