This registration section consists of 3 parts: Input
Instructions, Read VIN and Write VIN.
(a) Input Instructions: Explains the general VIN input instructions when using the intelligent tester.
(b) 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.
(c) Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is changed, or the vehicle VIN and ECM VIN do not match, the VIN can be registered or overwritten in the ECM by following this procedure.
