SERVICE UPDATE
SUBJECT:

Service Update for Inventory and Customer Vehicles
Heated and Ventilated Front Seats Inoperative with Remote Start
Expires with Base Warranty

MODELS:

2016 Chevrolet Corvette
Equipped with Automatic Transmission (RPO M5U) and Heated and
Ventilated Front Seats (RPO KQV)

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 body control module on certain 2016
model year Chevrolet Corvette vehicles equipped with an automatic transmission (RPO M5U) and
heated and ventilated front seats (RPO KQV). While the engine is running during a remote start,
and the remote start heated and ventilated seat feature is turned on in the vehicle personalization
menu, the heated and ventilated seats may not activate.
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 can be found in GlobalConnect,
under Departments, Service, Field Action Inventory Reports (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.
PART INFORMATION
No parts are required for this repair.

SERVICE PROCEDURE
Note: Carefully read and follow the instructions below.


DO NOT attempt to order the calibration number from GM Customer Care and Aftersales.
The calibration numbers required for this service procedure are programmed into control
modules via a Multiple Diagnostic Interface (MDI) with the calibration update. If you cannot
access the calibration, call the Techline Customer Support Center and it will be provided.



DO NOT program a control module unless directed to by a service procedure or a service
bulletin. If the control module is not properly configured with the correct calibration software,
the control module will not control all of the vehicle features properly.



Ensure the programming tool is equipped with the latest software and is securely connected
to the data link connector. If there is an interruption during programming, programming failure
or control module damage may occur.



Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. When required install the EL-49642 SPS
Programming Support Tool to maintain system voltage. If not available, connect a fully
charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT
connect a battery charger.



Turn OFF or disable systems that may put a load on the vehicles battery such as; interior
lights, exterior lights (including daytime running lights), HVAC, radio, etc.



During the programming procedure, follow the SPS prompts for the correct ignition switch
position.



Clear DTCs after programming is complete. Clearing powertrain DTCs will set the
Inspection/Maintenance (I/M) system status indicators to NO.

1. Install EL-49642 SPS programming support tool.
2. Access the Service Programming System (SPS) and follow the on-screen instructions.
3. On the SPS Supported Controllers screen, select K9 Body Control Module - Programming
and follow the on-screen instructions.
Note: When performing the Tire Pressure Monitor Sensor Learn during BCM setup, the EL46079 tire pressure monitor diagnostic tool must be used to activate each tire pressure sensor
for vehicles with UJM.
4. On the SPS Supported Controllers screen, select K9 Body Control Module - Setup (or
K9 Body Control Module - Configuration & Setup) and follow the on-screen instructions.
5. Check the driver information center display for additional messages regarding further
calibration instructions. If there are no additional driver information center instructions
present, programming is complete.
6. At the end of programming, choose the “Clear DTCs” function on the SPS screen.
7. If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the
K17 Electronic Brake Control Module after performing BCM programming and setup, do the
following:
7.1. Disconnect the scan tool from the X84 Data Link Connector.

DEALER PROGRAM RESPONSIBILITY
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your facility
for service in the future, and the vehicle is still covered under the New Vehicle Limited Warranty,
you must take the steps necessary to be sure the service update correction has been made before
selling or releasing the vehicle.
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in
dealers' possession and subject to this bulletin must be held and inspected/repaired per the
service procedure of this bulletin before customers take possession of these vehicles. Involved
vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for
demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned
Inventory System (CPOIS) will be de-certified and must be held and remedied per the service
procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global
Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS
system, or once again be used in the CTP program.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
