13417: Service Update for Inventory and Customer Vehicles - Engine Protection Mode Activated During Aggressive Driving - Expires with Base Warranty - (Jan 24, 2014)

Subject: 13417 – Service Update for Inventory and Customer Vehicles — Engine Protection Mode Activated During Aggressive Driving — Expires with Base Warranty

Models: 2014 Chevrolet Corvette
Equipped with a 6.2L Engine (LT1), 7-Speed Manual Transmission (MEP), and Wet Sump Oiling System

--------------------------------------------------------------------------------

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 reprogram the ECM, instrument cluster and on some vehicles, the BCM, HVAC, and radio modules, on certain 2014 model year Chevrolet Corvette vehicles, equipped a 6.2L engine (LT1), 7-speed manual transmission (MEP), and wet sump oiling system.

During very aggressive driving, such as right-hand turn maneuvers at high g forces, and when the driver stays in a low gear and forces high engine revs and high g forces for a sustained period of time, the engine protection mode (OSTER) will activate as designed. This mode will cause a reduction in engine power to prevent oil starvation and engine damage; however, there is no indication to the driver, in advance, that the mode has been activated.

In addition to the reprogramming, dealers will also provide the customer with an owner manual insert that describes a new DIC warning message that will appear when the engine protection mode is activated.

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.
