11195B - ROUGH IDLE, POOR DRIVEABILITY - REPROGRAM ENGINE CONTROL MODULE

SERVICE CAMPAIGN BULLETIN

CONDITION

General Motors has decided to conduct a Voluntary Emission Recall involving certain  2011 Buick LaCrosse, Regal; Chevrolet Equinox; and GMC Terrain vehicles equipped with a 2.4L gas engine (LAF). On these vehicles, the camshaft position actuator solenoid may stick, resulting in the illumination of the malfunction indicator light, rough idle, poor driveability, and/or possible stalling at low throttle opening.

CORRECTION

Dealers are to reprogram the engine control module and, if necessary, replace the camshaft position actuator solenoid valves.

VEHICLES INVOLVED

Involved are certain  2011 model year Buick LaCrosse, Regal; Chevrolet Equinox; and GMC Terrain vehicles equipped with a 2.4L gas engine (LAF).

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 recall 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 recall.

PARTS INFORMATION

Parts required to complete this recall are to be obtained from General Motors Customer Care and Aftersales (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

Determine the vehicle status.

• If the vehicle is still in dealer inventory, reprogram the ECM with the latest calibration. Refer to ECM Programming in this bulletin. Do NOT replace the camshaft position actuator solenoid valves.
• If the vehicle has been delivered to the customer, reprogram the ECM and replace the camshaft position actuator solenoid valves.  Refer to Engine Controls - Camshaft Position Actuator Solenoid Valve Replacement  in SI.

ECM Programming 

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) or Tech 2 R diagnostic scan tool and TIS2WEB with the calibration update. Use TIS2WEB on or after 6/23/11  to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided. Make sure your Tech 2 R diagnostic scan tool is updated with the latest software version or verify that the multiple diagnostic interface (MDI) that is being used is configured to the PC that will be used. Clear any codes and verify the condition has been corrected.

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 R PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage during programming.
2. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
   1. Connect the MDI to the vehicle. Connect the MDI to the programming terminal with a cable (USB or LAN).
   2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
   3. Select ECM Engine Control Module-Programming from the Supported Controllers screen.
   4. Follow the on-screen instructions.
3. Clear all DTCs.
4. If the vehicle has been delivered to the customer, replace the camshaft position actuator solenoid valves. Refer to Engine Controls - Camshaft Position Actuator Solenoid Valve Replacement  in SI.
5. CALIFORNIA, CONNECTICUT, MARYLAND, MASSACHUSETTS, MAINE, OREGON, VERMONT, & WASHINGTON vehicles only:  Install a Recall Identification Label.

RECALL IDENTIFICATION LABEL - CALIFORNIA/CONNECTICUT/MARYLAND/MASSACHUSETTS/MAINE/OREGON/VERMONT/WASHINGTON VEHICLES ONLY
