Diagnostic Fault Information

Circuit Description

The heated oxygen sensor (HO2S) heater reduces the time required for the oxygen sensor to reach operating temperature and maintains the

operating temperature during extended idle periods. When the ignition is turned to the ON position, ignition voltage is supplied directly to the

sensor heater. The Engine Control Module (ECM) controls the heater operation by first modulating the control circuit to ground when the sensors

are cold. This prevents the possibility of thermal shock to the sensor, from condensation build-up on the sensor, by controlling the sensors rate of

heating. After a predetermined amount of time, the ECM commands the heaters ON continuously. Once the sensor reaches operating temperature,

the ECM may modulate the heater control circuit to ground, to maintain a desired temperature.

The ECM controls the heater by grounding the control circuit with a solid state device called a driver. The driver is equipped with a feedback

circuit that is pulled-up to voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring

the feedback voltage.

2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Technical Service Bulletin # 01-07-30-042G Date: 110922

A/T - 2-3 Upshift or 3-2 Downshift Clunk Noise

INFORMATION

Bulletin No.: 01-07-30-042G

Date: September 22, 2011

Subject: Information on 2-3 Upshift or 3-2 Downshift Clunk Noise

Models:

2012 and Prior GM Passenger Cars and Light Duty Trucks

Equipped with 4L60-E, 4L65-E or 4L70-E Automatic Transmission (RPOs M30, M32, M70)

Supercede:

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 01-07-30-042F (Section 07 - Transmission/Transaxle).

Important

For 2005 model year fullsize utilities and pickups, refer to Corporate Bulletin Number 05-07-30-012.

Some vehicles may exhibit a clunk noise that can be heard on a 2-3 upshift or a 3-2 downshift.

During a 2-3 upshift, the 2-4 band is released and the 3-4 clutch is applied. The timing of this shift can cause a momentary torque reversal of the

output shaft that results in a clunk noise. This same torque reversal can also occur on a 3-2 downshift when the 3-4 clutch is released and the 2-4

band applied. This condition may be worse on a 4-wheel drive vehicle due to the additional tolerances in the transfer case.

This is a normal condition. No repairs should be attempted.

A new class of fuel called TOP TIER Detergent Gasoline is appearing at retail stations of some fuel marketers. This gasoline meets detergency

standards developed by six automotive companies. All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the

"Lowest Additive Concentration" recommended by the Canadian General Standards Board (CGSB). Those vehicles that have experienced deposit

related concerns may especially benefit from use of TOP TIER Detergent Gasoline.

Top Tier Fuel Availability

Chevron was the first to offer TOP TIER Detergent Gasoline in Canada. Shell became the first national gasoline retailer to offer TOP TIER

Detergent Gasoline across Canada. Petro-Canada began offering TOP TIER Detergent Gasoline nationally as of October 1, 2006. Esso began

offering TOP TIER Detergent Gasoline in May of 2010.

Gasoline Brands That Currently Meet TOP TIER Detergent Gasoline Standards

The following gasoline brands meet the TOP TIER Detergent Gasoline Standards in all octane grades :

- Chevron Canada (markets in British Columbia and western Alberta)

- Shell Canada (nationally)

- Petro-Canada (nationally)

- Esso-Canada (nationally)

- Sunoco-Canada (Ontario)

What is TOP TIER Detergent Gasoline?

TOP TIER Detergent Gasoline is a new class of gasoline with enhanced detergency and no metallic additives. It meets new, voluntary deposit

control standards developed by six automotive companies that exceed the detergent recommendations of Canadian standards and does not contain

metallic additives, which can damage vehicle emission control components.

Where Can TOP TIER Detergent Gasoline Be Purchased?

The TOP TIER program began in the U.S. and Canada on May 3, 2004. Some fuel marketers have already joined and introduced TOP TIER

Detergent Gasoline. This is a voluntary program and not all fuel marketers will offer this product. Once fuel marketers make public announcements,

they will appear on a list of brands that meet the TOP TIER standards.

Who developed TOP TIER Detergent Gasoline standards?

TOP TIER Detergent Gasoline standards were developed by six automotive companies: BMW, General Motors, Honda, Toyota, Volkswagen and

Audi.

Why was TOP TIER Detergent Gasoline developed?

TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. In the U.S., government regulations require

that all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep

engines clean. In Canada, gasoline standards recommend adherence to U.S. detergency requirements but do not require it. In fact, many brands of

gasoline in Canada do not contain any detergent additive. In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is

needed than what is required or recommended, and no metallic additives are allowed. Also, TOP TIER was developed to give fuel marketers the

opportunity to differentiate their product.

Why did the six automotive companies join together to develop TOP TIER?

All six corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency and the

intentional addition of metallic additives is an issue of concern to several automotive companies.

What are the benefits of TOP TIER Detergent Gasoline?

TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" recommended by

Canadian standards. Clean engines help provide optimal fuel economy and engine performance, and also provide reduced emissions. Also, the use

of TOP TIER Detergent Gasoline will help reduce deposit related concerns.

Who should use TOP TIER Detergent Gasoline?

All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the "Lowest Additive Concentration" recommended by

Canadian standards. Those vehicles that have experienced deposit related concerns may especially benefit from use of TOP TIER Detergent

Gasoline. More information on TOP TIER Detergent Gasoline can be found at this website, http://www.toptiergas.com/.

Body - Tapping/Clicking/Ticking Noise at Windshield Area

TECHNICAL

Bulletin No.: 08-08-48-003G

Date: January 28, 2013

Subject: Tapping, Clicking or Ticking Noise at Windshield Area (R&R Right and Left Windshield Side Reveal Moldings to Add Double Sided

Tape)

Models:

2007-2013 Cadillac Escalade Models

2007-2013 Chevrolet Avalanche, Silverado, Suburban, Tahoe

2007-2013 GMC Sierra Models, Yukon Models

Supercede:

This bulletin is being revised to add the 2013 model year. Please discard Corporate Bulletin Number 08-08-48-003F (Section 08 - Body and

Accessories).

Condition

Some customers may comment on hearing a tapping, clicking or ticking noise at the windshield area. This condition occurs more frequently while

driving at highway speeds and could be exaggerated on vehicles with front bug guard deflectors.

Cause

This condition may be caused by air/wind causing the windshield side reveal moldings to move, generating a noise.

Correction

Remove both windshield reveal moldings, add double-sided tape and re-install the moldings following the steps below:

1. Using tape (1) or a grease pencil, mark the position of the inboard edge (2) of both left and right reveal moldings onto the windshield,

following the contour of the molding.

2. Remove the left and right windshield side reveal moldings. Refer to Windshield Side Reveal Molding Replacement in SI.

3. Being careful not to affect the tape or grease pencil marks, clean and prep the glass at the seal interface with Glass Adhesion Promoter, P/N

12378555 (in Canada, use 88901239).

2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 343

4. Apply 3M Automotive Adhesion Promoter 06396, or equivalent, to the underside of the reveal molding seals.

Tip

An approximate 600 mm (24 in) length of tape should allow for overlap at the top to be trimmed back leaving a tail of release liner (1) and, at

minimum, should reach the fender cut line at the bottom.

5. Apply a 600 mm (24 in) length of 3M Automotive Acrylic Plus Attachment Tape 06386 (1.14 mm (0.045 in) thick x 6.35 mm (0.25 in)

wide), or equivalent, to both sides of the windshield. Ensure the tape (1) position is centered between the windshield edge (2) and the

tape/grease pencil line (3). Do not remove the release lining from the tape yet.

6. Reinstall the reveal molding to one side by sliding the molding downward and ensuring that the top lip is engaged at the upper edge of the

windshield.

2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 344

7. Install the fasteners to the reveal molding, starting from the top. Refer to Windshield Side Reveal Molding Replacement in SI.

8. Lifting the top edge of the reveal molding, grab the tail of the release lining and pull downward removing the lining.

9. Press or roll the reveal molding against the windshield ensuring adhesion of the tape to the glass.

10. Repeat steps 6-9 on the opposite side.

11. Remove tape or clean the grease pencil marks from the windshield.

12. If positioned correctly, trimming of the double sided tape should not be necessary, however inspect the reveal moldings for any tape not

covered and trim off any exposed tape.

Important

After taping the windshield reveal moldings, avoid washing the vehicle as well as excessive contact with the windshield reveal moldings for

a minimum of 72 hours.
