The only "reset" that I know of is the fuel maps. Disconnect the negative terminal of the battery for 5 minutes.

But I don't think that will fix it. Did you unplug any connectors or tap into any?

TSB:

EL03-004 NTB03-012 February 6, 2003

2003 MURANO; INTERIOR COURTESY LAMPS INOPERATIVE

APPLIED VEHICLE: 2003 Murano (Z50)

APPLIED DATE: Built before November 25, 2002

APPLIED VIN(S): Built before JN8AZ08T(*)3W103076, or JN8AZ08W(*)3W207958

IF YOU CONFIRM:
The interior “courtesy lamps” are inoperative on an applied vehicle.

NOTE: Courtesy lamps include map/dome and vanity lights.
DETERMINE IF: The Body Control Module (BCM) needs to be replaced.

ACTIONS:
• Follow the service procedure in this bulletin to diagnose the incident.

• If necessary, replace the BCM with the part number listed in the Parts Information.

NOTE: Before starting this Service Procedure, collect all vehicle keys and remote controls from the customer. If BCM replacement is needed, all the vehicle keys and remotes will need to be programmed into the new BCM.

My car was delivered that way. The dealer had to order a new circuit board and replace it. Be sure and take BOTH keys with you because they have to be re-programmed when the board is replaced
