** SOLUTION **
Cause

Hardware, software, and programming information for converting Incandescent lamps to
LED. Applicable to vehicles model year 2008 and newer.

Solution

Change Parameters
When Changing lights from Incandescent to LED change the following parameters and
parts on trucks build after 2008 and with US 2007 Emmisions.

Requirements
Light Control Module (LCM) Hardware part numbers - 20865208, 20976406,
21326144, 21803280, 23274017
Software part number - 21501276 or 21965197 or higher ( Update software
as needed )
Note: If parameters are not changed, the LCM will set an current below normal, or open
circuit fault
