SERVICE PROCEDURE

Engine Control Module Programming (Cadillac Vehicles)

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® and TIS2WEB with the calibration update. When using a MDI or Tech 2® for reprogramming, ensure that it is updated with the latest software version.

Use TIS2WEB on or after 1/9/11 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.

Capture and record Engine Oil Life information. Write down remaining oil life as a percentage.
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.
Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the MDI or Tech 2® to the vehicle. If using MDI, connect to programming terminal with the cable (USB or LAN).
2. Select J2534 MDI or J2534 Tech 2® 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.
Clear all DTCs using the Tech 2® or GDS.
Use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before completing the programming event.

NOTE:

If a programming failure occurs, refer to Engine Control Module Recovery Steps in this bulletin.

NOTE:

Repeat Steps 1-8 above IF another programming failure occurs. If the second attempt to reprogram in unsuccessful when following the Steps 1-8 above, then contact Techline Customer Support Center.

Engine Control Module Recovery Steps

Disconnect the programming device.
Power down the control modules connected to the GMLAN bus by disconnecting the positive battery cable for 2 minutes.
Reconnect the positive battery cable.
Determine which programming device will be used to perform the recovery steps.
- If using MDI, connect to the programming station or Notebook using a cable (LAN). Proceed to Step 5 and then Steps 6-8.
- If using a Tech 2® proceed to Steps 6-8.
Reboot the programming station or Notebook. This is to make sure nothing is in memory.
NOTE:
Selecting Replace and Reprogram from the Select Diagnostic Tool and Process Screen is REQUIRED because some of the calibrations may be erased from the initial attempt to reprogram the module.
Reprogram the engine control module. Select Replace and Reprogram from the Select Diagnostic Tool and Process Screen.
Follow the on-screen instructions to complete the programming event.
Clear all DTCs using the Tech 2® or GDS.

SEQ Programming Sequence ECM/TCM (Buick Enclave, Chevrolet Traverse, GMC Acadia, Saturn OUTLOOK)

Use TIS2WEB on or after 02/21/11 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.

Capture and record Engine Oil Life information. Write down remaining oil life as a percentage.
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.
Reprogram the engine control module (ECM) and the transmission control module (TCM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the MDI or Tech 2® to the vehicle. If using MDI, connect to programming terminal with the cable (USB or LAN).
2. Select J2534 MDI or J2534 Tech 2® and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3. Select SEQ Programming Sequence ECM/TCM from the Supported Controllers screen.

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.

OWNER LETTER

April, 2012

Dear General Motors Customer:

This notice is sent to inform you that General Motors is conducting a Customer Satisfaction Program that affects 2007 model year GMC Acadia; Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn OUTLOOK vehicles equipped with a V6 engine.

Your vehicle was designed and built to meet GM's high standards for quality and reliability. However, we have determined that under certain driving conditions, and with your vehicle's original oil change intervals, the timing chain could wear prematurely and cause the illumination of the Service Engine Soon light. Timing chain wear can be affected by the age of the engine oil and driving conditions.

What We Will Do: To ensure that your vehicle will not experience this condition, your GM dealer will change the calibration of the engine control module, including the engine oil life monitor, which in most cases will recommend more frequent oil changes. This calibration change will be performed for you at no charge until October 31, 2012 .

What You Should Do: The sooner your vehicle receives this new calibration, the more effective it will be, and so we recommend that you contact your GM dealer as soon as possible to schedule an appointment for this repair. Failure to complete this repair by October 31, 2012, may affect your eligibility for future repair coverage for the timing chain.

If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below.
