Visit Geno's Garage for Truck accessories.

Date: June 02, 2006

THE StarSCAN® FLASH FILES FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET.

StarSCAN® UPDATE CD 6.05 WAS THE LAST CD TO CONTAIN FLASH FILES.

NOTE: This bulletin applies to vehicles equipped with an Overhead Console (sales
code CUS) built on or before May 30, 2006 (MDH 0530XX).

Models: 2006 (DR/DH/D1) Ram Truck

Overview:
This bulletin involves selectively erasing and reprogramming the Cabin Compartment Node (CCN) with new software.

Symptom/Condition:
The vehicle operator may describe that the ambient temperature first displayed in the
overhead console is not accurate (displays -40°C or -40°F), when the ignition switch is
turned to the “On” position, then slowly updates to the outside ambient temperature as the
vehicle is driven.

NOTE: DO NOT reprogram the CCN if the overhead displayed temperature stays at
the -40°C (-40°F) reading after driving the vehicle for MORE THAN 3 minutes
and at speeds greater than 32 Km/h (20 mph). Check the system for an open
circuit condition.

Diagnosis:
Using a Scan Tool (StarSCAN®) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTC's are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.

If the vehicle operator describes or experiences the Symptom/Condition, perform the
Repair Procedure.
