Subject:11160 - Loss of Air Conditioning - Reprogram Body Control Module

Models:2011 Chevrolet Camaro

*THIS PROGRAM IS IN EFFECT UNTIL MAY 31, 2013*

Condition:

Certain 2011 model year Chevrolet Camaro vehicles may have a condition in which the air conditioning compressor may not turn on or turn off. This could cause the compressor to fail, resulting in a loss of air conditioning.

Correction:

Dealers are to reprogram the body control module.

Vehicles Involved:

Involved are certain 2011 model year Chevrolet Camaro vehicles.

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty Management system. Not all vehicles may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

Parts Information:

No parts are required for this program.

Service Procedure:

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. When using a MDI for reprogramming, ensure that is updated with the latest software version. Use TIS2WEB on or after 05/16/11 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.



For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.

1. Verify that there is a battery charge of 12 to 15 volts. The battery must be able to maintain a charge during programming. Only use an approved Midtronics® PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming. <LI type=1>Reprogram the body control module (BCM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
   2.1. Connect the MDI to the vehicle.
   
   
   
   
   
   
   2.2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
   
   
   2.3. Select BCM Body Control Module -- Programming from the Supported Controllers screen.
   
   
   2.4. Follow the on-screen instructions.

1. 
   Clear all diagnostic trouble codes (DTCs).
2. 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.

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 equipment, tools, 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 GM dealer for information on whether your vehicle may benefit from the information.

yeah i took my car in to have a few things done pro bono and the techs came across that TSB and thought it was a great idea to "update" the car, now i have tac control, stability control, and abs lights on in my dash. was told there was no fix for it yet. im more mad about the fact that there was nothing wrong with my car that would warrant the update and they went ahead and thought it was a good idea to just update the car.

No, i got a letter from GM saying my coupe is affected and eligible for the update. Anyone heard what exactly causes the problem and what they change in the BCM to fix it?

[Moriartii]

Mine was affected and I have a coupe.

Received my letter yesterday. Will bring in next week.

[Bob 2011]

Just got mine back today from having it done. The BCM is reprogrammed to make sure the compressor cycles as it was intended to. Otherwise you may have a compressor failure. I'd rather have a reprogram done than have a compressor replaced. It took maybe 30 minutes and all is fine.
