Cause

Correction
DO NOT REPLACE THE DRIVER DOOR SWITCH OR PASSENGER DOOR SWITCH.
Using SPS and Pass-Thru method, reprogram the driver door switch (DDS) and passenger door switch (PDS) with updated software calibrations. These new service calibrations were released with TIS satellite data update version 2.75 / 2006. As always, make sure your Tech 2(R) is updated with the latest software version.
After the reprogramming is completed, check and clear all DTCs that may have set as a result of the programming process.
