Fix for the Automatic Door Locks 2006-2007

redbugdave · December 23, 2006

One of the other truck forums I read has an interesting thread on a fix for the automatic door locks. On 2006-2007 trucks you have only 2 options...Mode 1: All doors lock when the transmission is shifted into gear. Mode 2: All doors lock when the vehicle speed is greater than 8 mph. This about drove me crazy with the truck locking automatically. Especially out in the woods hunting, letting people in and out of my truck.

But, new BCM calibrations have been released for the 2006 and 2007 model years to allow a Mode 3: No Automatic door locking (Manual).

I took my truck in the other day and had it done...free under warrantee. Now, I have full control over the doors, and can go back into the other modes if I like. (Manual is best).

Here's a link to the thread from the other forum with the bulletin, and postings. Enjoy! I suggest you print a copy of the bulletin and take it to the dealer, when you go. I was the first one to have it done at the dealer here in Columbia, SC...and they did not know anything about it till I showed them the bulletin.

Subject: Disabling Auto Door Locks - keywords dic ipc lock manual mode operation program reprogram unlock #PIT3189E - (12/21/2006)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may comment that they are unable to override the automatic door locking feature. In prior model years, customers were able to select "Doors Lock Manually" from the DIC. However, starting in the 2005 model year, this selection was removed.

Recommendation/Instructions:

Since the 2005 model year, all BCM's (Body Control Modules) are programmed from the factory to allow two personalized door lock settings:

Setting 1: All doors lock when the transmission is shifted into gear.

Setting 2: All doors lock when the vehicle speed is greater than 8 mph (13 km/h).

New BCM calibrations have been released for the 2006 and 2007 model years to allow a Setting 3: No Automatic door locking (Manual). This setting should ONLY be turned on at the owner's request. At this time there is NO new calibration available for the 2005 models or vehicles with manual transmissions. Use one of the following procedures below to disable the auto door lock feature.

Use the following procedure to turn on this feature for models:

2006 Cadillac Escalade, Escalade ESV, Escalade EXT

2006 Chevrolet Avalanche, Suburban, Tahoe

2006-2007 Chevrolet Silverado Classic

2006-2007 GMC Sierra Classic

2006 GMC Yukon, Yukon Denali, Yukon XL, Yukon Denali XL

Reprogram the BCM with updated calibrations currently available in Tis2Web. When at the "Calibration Selection" screen in Tis2Web select the "locking" tab and pick the calibration listed "auto door lock option enabled on dic".

On vehicles with Steering Wheel Controls (RPO UK3) use the controls to scroll through the personalization setting to the "Auto Door Lock" feature. There will be a new "Manual" selection now available to choose, along with the two previous selections "In Gear" and "With Speed".

On vehicles Without a Steering Wheel Controls (RPO UK3) use the owners manual to enter the door lock programming mode in section

Once in the programming mode press the lock side of the drivers power door lock switch, you will hear either one, two or NO chimes. One chime indicates you are in Setting 1 (lock in gear), Two chimes you are in Setting 2 (lock with speed) and NO chimes you are in Setting 3 (Manual). Continue to press the door lock switch to scroll through the 3 different selections until you hear the desired setting and then exit the programming mode by turning the ignition key on.

Use the following procedure to turn on this feature for models:

2007 Cadillac Escalade, Escalade ESV, Escalade EXT

2007 Chevrolet Avalanche, Silverado, Suburban, Tahoe

2007 GMC Sierra, Yukon, Yukon Denali, Yukon XL, Yukon Denali XL

Reprogram the BCM with updated calibrations currently available in Tis2Web. When at the "Calibration Selection" screen in Tis2Web select the "locking" tab and pick the calibration listed "auto door lock option enabled on dic".

On vehicles equipped with steering wheel controls (RPO UK3) DIC (Driver Information Center) control buttons are included. Use the DIC buttons to scroll through the personalization settings to the "Auto Door Lock" feature. There will be to two different settings: "Lock with speed" or "Lock in gear". You will notice there is NO new setting but also there will be no "check marks" next to any of the settings. This means the auto door lock feature is disabled. If there is a "check mark" next to one of the "Auto Door Lock" selections then the only way to remove the "check mark" is to scroll to "Factory Settings" and select "Restore", this will remove the "check mark" thus disabling the "Auto Door Lock" feature.

Note: Please keep in mind that if "Factory Settings Restored" is selected it will change all of the other personalization settings back to the factory settings and they will need to be reset back to the owners settings.

On vehicles without the DIC control buttons once the BCM is reprogrammed with the new calibration the "Auto Door Locks" will be disabled and can not be turned back on unless the BCM is reprogrammed back with the previous calibration.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

Somebody must really hate me.

I OWN A 2005!!!!!!

I sure hope they will eventually find a fix for my year. I somehow get the feeling that I will be left out in the cold on this one though.

same here...I really hate that d**n auto lock feature and the fact that the 2 key fobs are marked for driver 1 & 2 but was disabled for 2005 also.

Ya, I made the mistake of asking what the 1 and 2 ment on the fob's when I first picked up my new truck. Really ticked me off when I was told what they use to do but I had the pleasure of them doing absolutely nothing for my truck.
