HINT:

The VIN is in the form of a 17-digit alphanumeric vehicle identification number. An intelligent tester is required to resister the VIN.

1. DESCRIPTION 

   This registration section consists of three parts, Input Instructions, Read VIN and Write VIN.

   1. Input Instructions: Explains the general VIN input instructions using an intelligent tester.
   2. Read VIN: Explains the VIN reading process in a flowchart. This process allows the VIN stored in the ECM to be read, in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle's ECM, are the same.
