Lamp Out Indicator With Aftermarket Pick Up Box Installation

Date: June 20, 2003

Models: 2003 DR Ram Truck

Discussion:

In situations where an aftermarket utility box is installed after the removal of the original equipment pick up box, the lamp out indicator may illuminate. This is due to the use of aftermarket rear stop and turn signal lamps which use a dual filament bulb instead of separate circuits for the stop and turn indictor. The Front Control Module (FCM), monitors the current flowing through the stop and turn signal circuits to operate the lamp out feature. Most aftermarket rear stop and turn signal assemblies use dual filament bulbs with a common stop and turn circuit. The current flow through these units will be different than the original equipment lamps.

A new feature has been added to the FCM to allow the use of dual filament rear stop and turn signals. This feature is called, “Combined Rear Stop and Turn lamps” . It can be programmed into the FCM using the DRB® III on vehicles built after Aug. 6, 2003 (MDH - 0806XX). To program the feature, connect the DRB® III and make the following menu selections:

Item No.	Description
1	DRB Stand Alone
2	Body
3	FCM/IPM
9	Miscellaneous
4	Comb R Stop & Turn

Vehicles built prior to Aug. 6, 2003 with earlier version FCM’s are not equipped with this capability. The later version FCM, (p/n 56049681AB) can be installed in these vehicles to provide the feature. Vehicles purchased as “Cab Chassis” or “Box Off" are shipped with the feature activated from the factory and do not require programming.
