Visit Geno's Garage for Truck accessories.

Date: August 25,2006

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.

Models: 2007 (DR/DH/Dl) Ram Truck (Light and Heavy Duty)

NOTE: This bulletin applies to vehicles equipped with a gasoline powered engine
and an automatic transmission that were built prior to August 13, 2006 (MDH 0813XX).

Overview:
This bulletin involves selectively erasing and reprogramming the Totally Integrated Power
Module (TIPM) with new software.

Symptom/Condition:
The vehicle operator may notice at engine start, that the automatic transmission is in its
"Limp-in" mode. For vehicles equipped with a 42RLE transmission the transmission would
remain in 2nd gear. For vehicles equipped with a 545RFE transmission the transmission
would remain in 3rd gear.

The vehicle operator may experience this condition if:

- The ignition switch is turned to the "OFF" position, the ignition key is left in the ignition
switch, the TIPM times out and enters its 'sleep" mode, and then without removing the
ignition key the engine is started.

- At engine start, when the IOD fuse has previously been removed.

The transmission will remain in its "Limp-in" mode until the ignition key is turned to the "OFF"
position and then the engine is immediately restarted (TIPM is not allowed to time out).
When this action is taken the transmission will operate normally (no longer in "Limp-in" mode).

Diagnosis:
1. Connect and power up the StarSCAN.
2. From the Home menu, select "ECU VIEW".
3. Scroll down and select 'TIPMCGW".
4. Select "MORE OPTIONS'.
5. Select "ECU DETAILS"
6. Read the "Software (code) Part Number"'.

    a. If YES >>> then perform the Repair Procedure.
    b. If NO >>> then STOP. This bulletin does not apply.
