This Preliminary information communicates 2 diagnostic tips for the illuminated sill plate lights not working after installation



1 Affected Product





Some technicians may notice that the Sill plate lightening is inoperative after installing the LPO Illuminated Sill Plate kit.



This may be caused by one of the following reasons:

1) The light sensor needs to see a dark condition. To insure the vehicle is in the night mode, cover the ambient light sensor, and ensure the headlights tell tale is illuminated on the IPC.

2) The Ambient light sensor setting in personalization under the lighting tab is turned Off. Enable ambient lighting.



Before extensive diagnostics are performed, please check the two items listed above.
