The VIN is in the form of a 17-digit alphanumeric vehicle identification number. The Techstream is required to register the VIN.

  1. DESCRIPTION 
    NOTE:

    The Vehicle Identification Number (VIN) must be input into a replacement ECM.

    HINT: 

    This registration section consists of two parts: Read VIN and Write VIN.

    1. Read VIN: This process allows the VIN stored in the ECM to be read in order to confirm that the two VINs, the one provided with the vehicle and the one stored in the vehicle's ECM, are the same.
    2. Write VIN: This process allows the VIN to be input into the ECM. If the ECM is changed, or the ECM VIN and vehicle VIN do not match, the VIN can be registered or overwritten in the ECM by following this procedure.
