The reversing lamp system consists of the following components:
When the transmission is placed in REVERSE (R), the BCM provides voltage to the reversing lamps. The reversing lamps are located within the rear lamp assemblies.
When the transmission is in REVERSE, the PCM (gasoline engine) or the Transmission Control Module (TCM) (diesel engine) sends a message over the High Speed Controller Area Network (HS-CAN) to the Body Control Module (BCM) indicating the transmission is in REVERSE. The BCM provides voltage to the reversing lamps when it receives the message that the transmission is in REVERSE and the ignition is in the RUN state. You could have a transmission range sensor problem , check to see if it is adjusted correctly ! Need to have a scan tool to make sure the BCM is receiving signal from the PCM . This is complex for someone who doesn't deal with or know about serial data communications ! All it is ,is electric inputs to a control module, then the control module configures it into data bits an bytes 1's an 0's then sends it out on the Data bus. The module that needs this info reads it an turns on the lights.This system can set codes in the bcm ,leading to a problem.

The Town & Country gets a new, simplified powertrain lineup for 2011. The new Pentastar 3.6-liter V-
6 engine that produces a best-in-class 283 horsepower and 260 lb.-ft. of torque, yet delivers excellent
fuel economy, powers the entire lineup. The Pentastar V-6 engine is mated to Chrysler Group LLC's
62TE six-speed automatic transmission. Chrysler Group was the first manufacturer to offer a sixspeed
transmission in a minivan, debuting on the 2008 Chrysler Town & Country. New for 2011 is a
fuel economizer mode switch, a driver-selectable engine economy mode which assists drivers to
maximize fuel efficiency while driving. All the economy mode really does is to take the transmission out of sort mode which means it will have lower shift points and not rev up and produce as much torque as it would otherwise that's all. You should get around 17mpg city and around 24 highway dependant on your driving habits. It is your personal preference whether you choose to use this function or not. Try using it in econo mode for 2 weeks and without for 2 weeks, to notice the difference while driving and fuel economy, then you can decide your preference. Nice vehicle
