DATE: May 31, 2006
THE StarSCAN(R) FLASH FILES FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET.
StarSCAN(R) UPDATE CD 6.05 WAS THE LAST CD TO CONTAIN FLASH FILES.
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 18-005-06 REV. A, DATED APRIL 26, 2006, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT:
Flash: DTC Correction, Turbocharger Protection, And Clutch Durability Improvement
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the PCM (Cummins) with new software.
MODELS:
2006 DH/D1 Ram Truck Heavy Duty
NOTE:
This bulletin applies to Ram trucks equipped with the 5.9L Cummins 24-valve diesel engine (sales code ETH) built on or after June 9, 2005 through and including May 31, 2006 (MDH 0609XX and 0531XX).
SYMPTOM/CONDITIONS:
The PCM software has been revised to address the following issues:
1. A MIL may illuminate due to one or more of the following Diagnostic Trouble Codes (DTC's):
a. P0071 - Inlet Air Temperature Sensor Rationality
b. P0111 - Intake Air Temperature (IAT) Sensor Rationality
c. P0514 - Battery Temperature Sensor Rationality
d. P0191 - Fuel Pressure Rationality
2. Turbocharger durability improvement. Implemented a engine speed limitation when cold, to protect the turbocharger bearings.
3. Clutch durability improvement. Implemented a minimum engine speed limitation when launching vehicle from a stop, to protect the clutch.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
Before performing this Repair Procedure, the operating software in the StarSCAN(R); must be programmed with software release level 6.06 or higher.
The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. Make sure the StarSCAN(R) is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN(R) for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation", or refer to the StarSCAN(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the 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(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Power ON the StarSCAN(R).
5. Retrieve the old PCM (Cummins) part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the PCM (Cummins) 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:
If the PCM (Cummins) is not operational, the "PCM (Cummins) part number" can be obtained from the label on the controller. If the label on the controller is not legible, record the "Reference No." for use later. The "Reference No." is located in the Reference No. box at the top, center of the Engine Data Plate (Fig. 1). Do not use the reference number shown in the figure. The Engine Data Plate is located on the intake side of the breather cover or affixed to the APPS bracket.
6. Is "WCM - Wireless Control Module" displayed in the "ECU Overview" screen list of modules?
a. Yes >> go to Step # 7.
b. No >> go to Step # 8.
7. Enter the Wireless Control Module (WCM) Secret Key information. Using the StarSCAN(R) at the "ECU Overview" screen:
a. Select "WCM"
b. Select "Misc. Functions"
c. Select "PCM Replacement"
d. Follow the on screen instructions.
e. When complete proceed to Step # 9.
8. Enter the VIN into the ECM. Using the StarSCAN(R) at the "ECU Overview" screen:
a. Select "PCM"
b. Select "Misc. Functions"
c. Select "Check PCM VIN"
d. Follow the on screen instructions.
e. When complete proceed to Step # 9.
NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules (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.
NOTE:
The following step is required by law when reprogramming a ECM and/or TCM.
9. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label (Fig. 2).
