For Trailer Tow Lamps Inoperative Indicating Short Circuits In The Wiring
On The Trailer Or P1277 For No Crank - Starter Solenoid Current Excessive.

Visit Geno's Garage for Truck accessories.

Date: May 10, 2006

THIS BULLETIN IS BEING PROVIDED IN ADVANCE. THE StarSCAN® FLASH FILES
FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET ON OR AFTER
MAY 15, 2006.

NOTE: The StarSCAN® must be updated to software release level 6.06 or higher,
available May 15, 2006. The software release level is visible in the blue
header at the top of the StarSCAN® screen.

Models: 2006 (DR/DH) Ram Truck

Overview:
This bulletin involves Flash Reprogramming the Totally Integrated Power Module (TIPM).

Symptom/Condition:
Customer may experience any of the following TIPM Diagnostic Trouble Codes (DTC's)
with associated symptoms:

• B178C - Left Stop Turn Over Current - Load on Left Stop/Turn circuit has exceeded 15 amps.
• B166C - Right Stop turn Over Current - Load on Right Stop/Turn circuit has exceeded 15 amps.
• B2215 - Internal Fault - An Internal Fault code counter has exceeded its limit and an output is disabled.
• P1277 - Fault Code Counter Reaches Upper limit Start Solenoid Circuit Over Current (Start Solenoid Current has exceeded the Upper Limit of 75 amps). Can be accompanied by fault code B2215, indicating that the faulted condition has been seen by the TIPM more than 250 times. If the B2215 fault code is present, the Output circuit of the TIPM will not function, resulting in a no-crank condition.

Discussion:
DTC'c B178C, B166C and P2215 indicate that short circuits exist in the wiring on
the trailer. The fault is set when the TIPM has seen loads on the circuit greater than
15 amps. TIPM retries the output on each ignition cycle or request (brake or turn
signal activation) to attempt to enable the output in case of an intermittent faulted
condition. The short circuits are usually intermittent and will require diagnosis and
repair. If Present, the B2215 fault code indicates that the TIPM has seen the faulted
condition >250 times and has turned off the output to protect the system. TIPM
trigger points for the trailer tow outputs has been increased from 15 amps to 17.5
amps, and the fault reporting strategy has been changed to be less susceptible to
trailer wiring problems. With this service flash, the TIPM will no longer permanently
deactivate the trailer tow outputs and the B2215 DTC will no longer be set.
- Each of these DTC's, including B2215 - Internal Fault, can be cleared from the
TIPM module memory but this can only be done a maximum of 5 times. The TIPM
module will be rendered inoperative on the sixth attempt and must be replaced.
- DCT B2215 - Internal Fault does not mean that the TIPM module is defective.
- DCT P1277 - Start Solenoid Circuit Over Current - The TIPM Module Monitors
starter Solenoid Current and contains a set point of 75 amps to trigger the DTC.
When this DTC is set, the TIPM renders the starter solenoid inoperative for that
ignition cycle, to protect the wiring. If the B2215 fault code (FCM Internal Fault) is
shown in addition to the P1277 code, this means that the Over Current Condition
has been seen by the TIPM module more than 250 times. On Diesel engine
equipped trucks there can be normal situations where the starter solenoid current
can exceed 75 amps. This software will change the DTC trigger to 100 amps.

Diagnosis:
If any of the DTC's listed above are present, perform the Repair Procedure.

Special Tools/Equipment Required:

NPN	Battery Charger
9097A	Special Tool, Bluetooth UConnect Flash Adapter
CH9401	StarSCAN® Tool
CH9404	StarSCAN® Vehicle Cable
CH9409	StarSCAN® Documentation Kit
CH9410	StarSCAN® Ethernet Cable, 12 ft.
CH9412	StarSCAN® Software Update Device Kit
	TechCONNECT PC or equivalent

NOTE: StarSCAN® Update CD 6.06, available May 15, 2006, is required to perform
this Flash.

Repair Procedure: 

USING THE INTERNET TO RETRIEVE THE FLASH FILE:

NOTE: When performing this Repair Procedure, the software release level in the
StarSCAN®; must be programmed with 6.06 level software or higher. The
software release level is visible in the blue header at the top of the
StarSCAN® screen.

NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, to take advantage of this feature you must first configure the
StarSCAN® for your dealership's network. Make sure the StarSCAN® is
configured to the dealership's network before proceeding. For instruction on
setting up your StarSCAN® for the dealer's network refer to either:
“DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online
Documentation”, or refer to the StarSCAN® Quick Start Networking Guide.
The StarSCAN® Quick Start Networking Guide is also available on the
www.dcctools.com website under the "Download Center".

NOTE: If this flash process is interrupted/aborted, the flash should be restarted.

1.	Install a battery charger and verify that the charging rate provides approximately 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete.
2.	Connect the CH9410 StarSCAN® ethernet cable to the StarSCAN® and the dealer's network drop.
3.	Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle.
4.	Power ON the StarSCAN®.
5.	Retrieve the old TIPM part number. Using the StarSCAN® at the “Home” screen:     a. Select “ECU View”     b. Touch the screen to highlight the TIPM in the list of modules.     c. Select “More Options”     d. Select “ECU Flash”     e. Record the part number at the top of the “Flash PCM” screen for later reference.     f. Select “Browse for New File”. Follow the on screen instructions.     g. Select “Download to Scantool”.     h. Select “Close” after the download is complete, then select “Back”.     i. Highlight the listed calibration.     j. Select “Update Controller”. Follow on screen instructions.     k. When the update is complete, select “OK”.     l. Verify the part number at the top of the “Flash PCM” screen has updated to the new part number.
NOTE: Due to the TIPM programming procedure, a DTC may be set in other modules (PCM, TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the “Home” screen select “System View”. Then select “All DTCs”. Press “Clear All Stored DTCs” if there are any DTCs shown on the list.

Policy:    Reimbursable within the provisions of the warranty.
