KL 58g is an outputpulse width modulated control signal from the LCM III. The duty cycle changes when theLCM III detects a change in the voltage drop at the light dimmer input signal.Interior Door Handle Lighting is on whenever the vehicles lights are switched on.139EXTERIOR DOOR HANDLE LIGHTINGCOMPONENTS/OPERATIONControl Module:The Visual Entry AidControl Module is located in the electricalcarrier forward of the glovebox.To control the system, the Visual Entry Aidcontrol module requires:••••KL 30KL 15KL 31Interior Light control signal (GM Output)CONTROL MODULEThe GM III controls the soft on/off feature of the vehicle interior lights bya pulse width modulated control signal (IB). Signal IB is also an inputsignal for the Visual Entry Aid control module which is an input requestto simultaneously control (soft on/off) each exterior door light source.Control Module Function:Lights ON:Lights OFF:The exterior visual entry aid lighting is activated “on” when the vehicle interi-or lights are activated “on” automatically by the GM III.Immediately after KL 15 recognition (immediate off -- no soft off function).Soft off after a short delay once all doors are closedAfter a maximum of 20 seconds “on” time (control module switches exteriorvisual entry aid lighting off regardless of interior light status).140Light Source Modules:Mounted in each door are thelight source modules.
