Thanks in advance for your help
When you say "not starting" do you mean the engine cranks but doesn't catch, or that it won't even crank?
Maybe I or your regular host here could look up if there is a TSB or other info on your particular problem.
VISITING HOST
I apologize for the problems you are experiencing with your vehicle. By chance, have you spoken with GM Customer Assistance? Please keep me posted on any information from the dealership.
Thank you,
Caron, GM Customer Service

Supercede:This bulletin is being revised to add the 2007 Silverado/Sierra Classic models. Please discard Corporate Bulletin Number 03-05-25-007C (Section 05 - Brakes).
Condition
Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set.
Cause
The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface.
Correction
Measure AC voltage and clean the wheel speed sensor mounting surfaces.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in the General Information sub-section of the Service Manual.
2. Disconnect both the front wheel speed sensor connectors at the frame and harness.
3. Place a Digital Volt Meter (DVM) across the terminals of each wheel speed sensor connector.
4. Rotate the wheel clockwise approximately one revolution per second. The minimum reading should be at least 350 ACmV's. If the reading is less than 350 ACmV's, remove the wheel speed sensor. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual.
5. Plug the wheel speed sensor bore in order to prevent debris from falling into the hub during service.
6. Clean the wheel speed sensor mounting surface using a wire brush, sand paper, emery cloth, scotch brite, or other suitable material. Be sure to thoroughly clean the wheel speed sensor surface. There should be no rust or corrosion.
7. Check the sensor head to determine if it has been warped/distorted due to the corrosion build up or other causes. Check the mounting surface on the sensor head for flatness by placing it on the edge of a metal machinists scale or other suitable straight edge to measure the flatness. Check the sensor for flatness in multiple (minimum 3) positions/directions. If the sensor head is distorted, replace the sensor.
8. Apply (spray) two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) to the complete sensor mounting surface on the bearing hub. Allow to dry for 3-5 minutes between coats. Use ONLY Rust Penetrating Lubricant, P/N 89022217 (in Canada, P/N 89022218).
9. When the corrosion inhibitor is dry to the touch (about 10 minutes), apply a thin layer of bearing grease to the hub surface and sensor O-ring prior to sensor installation. Use ONLY Wheel Bearing Lubricant, P/N 01051344 (in Canada, P/N 993037).
10. Install either the original sensor or a new one in the hub. Ensure that the sensor is seated flush against the hub. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual.
11. Place the DVM across the sensor terminals and recheck the voltage while rotating the wheel. The voltage should now read at least 350 ACmV's.

What is the auxillary control module, where is it and how do I recalibrate the system?
Thanks
I would love to hear your advice on this. Thank you in advance.

I would love to hear your advice on this. Thank you in advance.
I'm sorry to read about the difficulties you're having with your Escalade. Are you planning on getting this looked into? We're happy to look into this further with you if you like.
Best,

The following is our process:
We would set up a Service Request through our department (would need your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your preferred dealership). If the transmissions shop you visited was not one of our dealerships, we would have you set up a diagnostic appointment with your preferred dealer (would involve a diagnostic fee) for them to look into the vehicle and determine the source of the transmission concern you're having. From that point, we would look at what it would take to repair the vehicle and we would consider any available options. I can't promise up front what the end result of the case will be, but our priority is to resolve any concern that you're experiencing and have you leave satisfied with your vehicle.
If this sounds like something you are interested in pursuing, please send the request information to socialmedia@gm.com and we will go from there.

It looks like you've already gotten some feedback from kasmir; if we can look into recall or warranty information for you, or if you would like for us to be involved in the process of you working with a dealership to get this looked into, please send the last 8 digits of your VIN as well as a brief summary of the situation to socialmedia@gm.com
All the best,

Thanks.
any one have any Idea?
Thank you
i have Escalade 07, and my problem started three weeks ago while i was driving on the highway the radio went off for a moment and then back on, and a message "Stabilitrak off" began flashing...
however, i went to the dealer trying to fix the radio disconnecting problem with no avail. no one could help me to diagnose and fix this problem!
then, while i was driving home (thre days ago), the doors locks began locking and unlocking, chiming, warning lights, and the vehicle became unstable/normal...
at that night i went home and google any info regarding to my escalade problem till i went through some posts here and i figure out that it could be from the ground cable connected to the battery.
finally, i fixed the ground cable myself and everything (till now) is fine and the car back to normal...thanks God and to you guys.
now my problem in the message "Parking assistant Off", it's still comes on the board, and the Parking Assistant Button flashing...
any idea how to fix it?
pls help, guys
thanks
Has the 6.0. Drove South to sea level from Vail CO. Would the change in altitude have anything to do with it. Do I need to make any adjustments regarding the fuel system etc. Next fill up will be 91 octane to see if that helps. If you want to copy me also pls do. tmkkel@yahoo.com
Many Thanks,
Todd Keleske
I ran the diagnostic and I got the following:
Only the Middle (amber) blinked 4 times, then stopped and the red light blinked few times... then back to blinking the normal ON-OFF-ON about 2 times.
I could be wrong but I thing the amber blinking means "reverse input wiring". What is this and what does that mean? Can I fix this code?
I know the last one...the red means the driver side corner sensor is bad but this amber "reverse input" has me confused.
Any help would be AMAZING
