SERVICE INFORMATION

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 lock all doors when the transmission is shifted into gear or vehicle speed is greater than 8 mph (13 km/h). There is no option to disable the auto door locks from the factory, but if an owner wishes to have the auto door locks disabled, the following procedure can be performed by the dealership:

NOTE:

Use the appropriate procedure below (either 1 or 2) for the Year and Model vehicle you are working.

Use the following procedure to disable the auto door locks on the models listed below:
2007 - 2014 Cadillac Escalade Models

2007 - 2013 Chevrolet Avalanche, Silverado (new body style), Suburban, Tahoe

2007 - 2013 GMC Sierra (new body style), Yukon Models

2014 Chevrolet Silverado 2500/3500, Suburban, Tahoe

2014 GMC Sierra 2500/3500, Yukon Models

A. Reprogram the BCM with updated calibrations currently available in Tis2Web. When viewing the "Calibration Selection" screen in Tis2Web, select "locking" (should be highlighted in Red) and pick the calibration listed as "(Per Customer Request Only) Auto door locks off, option no longer in DIC".

NOTE:
For the 2010 thru 2014 Model years the calibrations are no longer selectable in Tis2Web and Techline Customer Support (800-828-6860) must be contacted to obtain the calibrations.

NOTE:
Techline Customer Support MAY charge a fee for these Calibrations.

B. After reprogramming the BCM, use the DIC controls (RPO UK3) to scroll through the personalization settings to the "Auto Door Lock" feature. There will be 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 owner's preferences.

On vehicles without the DIC controls, once the BCM is reprogrammed with the new calibration the "Auto Door Locks" will be disabled and there is no way to turn the Auto Door Locks back on unless the BCM is reprogrammed with the previous calibration.
Use the following procedure to disable the auto door locks on the models listed below:
2006 Cadillac Escalade, Escalade ESV, Escalade EXT

2006 Chevrolet Avalanche, Suburban, Tahoe

2006 - 2007 Chevrolet Silverado Classic (old body style)

2006 - 2007 GMC Sierra Classic (old body style)

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

NOTE:
NO new calibrations are available for the 2005 models or vehicles with manual transmissions.

A. Reprogram the BCM with updated calibrations currently available in Tis2Web. When at the "Calibration Selection" screen in Tis2Web select "locking" (should be highlighted in Red) and pick the calibration listed "(Per customer request only) Auto Door Lock option ENABLED on DIC".

B. After reprogramming the BCM, vehicles with Steering Wheel Controls (RPO UK3) can 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".

C. After reprogramming the BCM, vehicles without Steering Wheel Controls will need to enter the door lock programming mode procedure located in section 2 of the owner's manual. Once in the programming mode press the lock side of the driver's 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.

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.
