Tech Tips
The VIN is a 17-digit alphanumeric vehicle identification number. The GTS is required to register the VIN.
DESCRIPTION
Tech Tips
This registration section consists of 2 parts: Read VIN and Write VIN.
Read VIN: This process allows the VIN stored in the ECM to be read in order to confirm that the 2 VINs, provided with the vehicle and stored in the vehicle ECM, are the same.
Write VIN: This process allows the VIN to be input into the ECM. If the ECM is replaced, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
