Campaign - Engine Serial Number Not In ECM: Overview

SERVICE UPDATE

Bulletin No.: 12218

Date: October 22, 2012

Subject: ---12218 Service Update for Inventory and Customer Vehicles Engine Serial Number Not Present in ECM Expires with Base Warranty

Models:
2013 Chevrolet Express
2013 GMC Savana
4500 Series Cutaway Vans

This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.

Purpose

This bulletin provides a service procedure to manually enter the engine serial number (ESN) into the engine control module ECM on certain 2013 model year Chevrolet Express and GMC Savana 4500 Series Cutaway vans. In the future, the ESN will be required for vehicle inspection and maintenance I/M testing in some states and provinces.

This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.

Vehicles Involved

All involved vehicles are identified by VIN in the Global Warranty Management System - Investigate Vehicle History Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

Additionally, a list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility.
