Subject: 11137 - Product Enhancements

Models:
2011 Chevrolet Volt

**********THIS PROGRAM IS IN EFFECT UNTIL SEPTEMBER 30, 2013.**********

Condition

A software update is available for certain 2011 model year Chevrolet Volt vehicles. This software update will address several customer concerns, including the operation of the Heating, Ventilation, and Air Conditioning (HVAC) blower motor after using the remote start feature, intermittent navigation radio issues, and reduced fuel economy under certain conditions. A revised fuse location label is also available for installation.

Correction

Dealers are to reprogram various modules with updated software and calibrations, and install a revised fuse location label.

Vehicles Involved

Involved are certain 2011 model year Chevrolet Volt 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 dealers through the GM GlobalConnect Recall Reports. 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

Important
A supply of labels required to complete this program were pre-shipped to involved dealers of record. This pre-shipment began the week of July 18, 2011 and was 100% of each dealer's involved vehicles. Pre-shipped parts will be charged to dealer's open parts account.

Additional labels, if required, are to be obtained from GMCC&A Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.





Service Procedure

Note
A vehicle charge cord is required to complete the programming event. If your dealership does not have a vehicle charge cord, contact the customer to inform them that a vehicle charge cord is required to complete the programming event. Ensure the customer brings their vehicle charge cord on the scheduled service date for the programming event.

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) and TIS2WEB with the calibration update. When using the MDI for reprogramming, ensure that it is updated with the latest software version. Use TIS2WEB on or after 08/04/11 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.

Note
Some modules may require up to 10 minutes to program. Do not interrupt module programming. The programming of these modules may take in excess of 1 hour to complete.

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(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming.
2. Reprogram the modules listed in the Module Programming Table. Refer to SI and Service Programming System (SPS) documentation for programming instructions.

1. Connect the MDI to the vehicle. Connect the MDI to the programming terminal with a cable.
2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.

Caution
Program the modules in the order indicated in the programming order section of the Module Programming Table. Carefully read and follow on-screen instructions in TIS2WEB to avoid module damage.

3. Select the appropriate module from the Supported Controllers screen. Refer to Module Programming Table for module programming order and module description information.

Note
Carefully read and follow on-screen programming instructions in SPS.

4. Follow the on-screen instructions.

3. Clear all DTCs after programming the last module.

Note
After programming the seven (7) modules, a window relearn calibration may be required. Refer to PIC 5523 if you are not successful in programming the seven modules, the vehicle will not crank, or the "Waiting to Initialize" message is displayed. If one of the modules locks up during SPS programming, please contact TCSC for further assistance.

4. Write warranty codes for module programming events in the repair order (RO).
5. Proceed to the Rear Compartment Fuse Block Label procedure below.





Rear Compartment Fuse Block Label





The rear compartment fuse block label is on the left side (driver's side) of the rear compartment behind a removable cover (1). Open the latch to remove the cover and access the fuse block label (2).

1. Inspect the part number, located in the bottom right corner of the label.

- If the label part number is 20972788, the label is correct. No further action is required.
- If the label part number is 20878465, the label is incorrect. Proceed to the next step and install the new label.





2. Clean the existing rear compartment fuse block label with isopropyl alcohol and paper towel or shop cloth.
3. Wait 30 seconds before affixing the new rear compartment fuse block label over the old label.
4. Install the rear compartment removable cover.
5. Close the rear compartment hatch.

Courtesy Transportation - For US and Canada

The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
