REGISTRATION
NOTICE:
The Vehicle Identification Number (VIN) must be input into the replacement ECM.

The VIN is in the form of a 17-digit alphanumeric vehicle identification number. A hand-held tester is re-
quired to register the VIN.
1. DESCRIPTION
This registration section consists of three parts, Input Instructions, Read VIN and Write VIN.
(a) Input Instructions: Explains the general VIN input instructions using a hand-held tester.

hicle'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 VIN and VIN do not match, the VIN can be registered, or over-
written in the ECM by following this procedure.
