Saturn OUTLOOK vehicles that are equipped with a 2.8L/3.6L V6 engine (LP1/LY7/LLT), under
certain driving conditions, and with the vehicle's original oil change intervals, the timing chain
could wear prematurely and cause the illumination of the Service Engine Soon light
SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 120,000
miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in

information in SI.
Refer to the appropriate diagnostic
• If the timing chain does NOT require replacement, proceed to Step 2 to determine if the
ECM requires reprogramming. This special coverage will cover this ECM reprogramming.
Inform the customer that any additional diagnosis and repairs are not covered under this
special coverage.
• If the timing chain requires replacement, refer to the appropriate timing chain replacement
procedure in SI. After the timing chain has been replaced, proceed to Step 2.
2.
Determine if the ECM was reprogrammed by searching the warranty transactions for labor
code V2385 or T5900. If the ECM was reprogrammed (labor code V2385 or T5900 found),
no further action is required.
•
If the ECM was NOT reprogrammed (labor code V2385 or T5900 NOT found), proceed to
Engine Control Module Programming (Cadillac Vehicles) or SEQ Programming Sequence

below.
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.
1. Capture and record Engine Oil Life information. Write down remaining oil life as a
percentage.
2. 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.
3. Reprogram the engine control module (ECM) . Refer to SI and Service Programming System
(SPS) documentation for programming instructions, if required .

5. 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 .
Engine Control Module Recovery Steps
1.
Disconnect the programming device.
2.
Power down the control modules connected to the GMLAN bus by disconnecting the positive
battery cable for 2 minutes.
3.
Reconnect the positive battery cable.
4.
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.
5.
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.
6.
Reprogram the engine control module. Select Replace and Reprogram from the Select
Diagnostic Tool and Process Screen.

COURTESY TRANSPORTATION - For US and Canada
The General Motors Courtesy Transportation program is intended to mm1m1ze 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.

Cadillac CTS, SRX, or STS; 2009 model year Bpick Enclave; Chevrolet Traverse, GMC Acadia,
or Saturn OUTLOOK, your satisfaction with our product is very important to us.
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.
In April of this year, we sent you a letter informing you of a Customer Satisfaction Program to
correct this condition. That program was available until October 31, 2012, and has now expired.
However, General Motors is providing owners with additional protection for the timing chain. If
premature wear of the timing chain occurs on your 2007 model year GMC Acadia or Saturn
OUTLOOK; 2007.:2009 model year Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave,
Chevrolet Traverse, GMC Acadia, or Saturn OUTLOOK vehicle, equippect with a 2.8U3.6L V6
engine, equipped with a V6 engine; within 10 years of the date your vehicle was originally placed
in service or 120,000 miles, whichever occurs first, the condition will be repaired. for you at no
charge. Diagnosis or repair for conditions other than the condition described above is not
covered under this special coverage program.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that
the Service Soon Engine light has illuminated due to timing chain wear.
What You Should Do: If you believe that your vehicle's Service Engine Soon light has
illuminated due to timing chain wear, repairs and adjustments qualifying under this special
coverage must be performed by a GM dealer. You may want to contact your dealer to find out
how long they will need to have your vehicle so that you may schedule the appointment at a time
that is convenient for you. This will also allow your dealer to order parts if they are not already in
stock. Keep this letterwith your other important glove box literature for future reference.
Reimbursement: If you have paid for repairs for the condition described in this letter and have
not submitted for reimbursement, please complete the enclosed form and pr?sent itto your dealer
with all required documents. Working with your dealer will expedite your request, however, if this
is not convenient, you may mail the completed form and all required dbcurnents to
Reimbursement Department; PO Box 33170, Detroit, Ml 48232-5170. The completed form and
required documents mustbe presented to your dealer or received by the Reimbursement
