This informational bulletin provides information on Some technicians may comment that they are unable to break a vehicles build information down using investigate vehicle history (IVH). This may be due to a technical error within the database. If you encounter a vehicle that is unable to be broken down within the IVH system, cross reference the SPID (Service Parts ID Label) (located on the passenger front door) with RPOs listed within Service Information (SI) or the Electronic Parts Catalog (EPC).
