Bulletin 06-08-64-014 originally applied to the 2007 Escalade, Tahoe and Yukon.
The 2006-07 Lucerne and DTS have now been added.
Some customers may comment on any of the following conditions:
- Front door locks inoperative
- Passenger power window inoperative
- Door courtesy lamps inoperative
- Heated/cooled seat indicators inoperative
- Or any other driver or passenger door function issue that can be resolved by an ignition cycle.
TIP: Customers may comment that a vehicle ignition cycle typically cures the symptoms.
Do not replace the driver door switch or passenger door switch. These conditions may be due to a software anomaly within the driver and passenger door switches.
Reprogramming
Using SPS and Pass-Thru method, reprogram the driver door switch (DDS) and passenger door switch (PDS) with updated software calibrations.
TIP: As always, be sure your Tech 2 is updated with the latest software version. New service calibrations were released with TIS satellite data update version 2.75 / 2006.
After the reprogramming is completed, check and clear all DTCs that may have set as a result of the programming process.
