THIS BULLETIN IS BEING PROVIDED IN ADVANCE **AS INFORMATION**. DO NOT ORDER PARTS OR PERFORM ANY ACTIONS RELATED TO THIS BULLETIN.
Models: 1998.5-2003 (BR/BE, DR) Ram Truck
19981/2-2002 (BE/BR) Ram Truck
2003 (DR) Ram Truck
NOTE. THIS BULLETIN APPLIES TO ALL RAM TRUCKS EQUIPPED WITH THE 5.9L CUMMINS 24-VALVE DIESEL ENGINE (ETC & ETH SALES CODES).
Mopar is currently phasing out pre-programmed Cummins Diesel Engine Control Modules (ECM). New modules will no longer be preprogrammed when received from Mopar. Replacement of future ECM's will require programming utilizing the DRBIII and MDS2. 1998 1/2 - 2002 modules will cause the "Wait to Start" light to flash, indicating the module has not been programmed.
NOTE: EXTREME CARE MUST BE TAKEN WHEN CHANGING THE CALIBRATION OF AN UNPROGRAMMED ECM. DO NOT RANDOMLY SELECT A CALIBRATION. IF IN DOUBT, CONTACT THE S.T.A.R. CENTER FOR ASSISTANCE. INSTALLING AN INCORRECT CALIBRATION INTO AN ECM CAN CAUSE SEVERE ENGINE DAMAGE.
1. If possible, record the old ECM part number through the module info screen.
2. Install the new ECM.
3. Install a battery charger and verify battery charge is above 11.5 volts.
4. Connect the DRBIII and the MDS2 to the vehicle. Verify "DRBIII Status: Connected".
5. Verify that the VIN displayed on the screen is correct. If the VIN is not displayed or is not correct, manually enter the VIN. Select "OK".
6. Enter the information requested by the "New Session Setup" window. Select "OK".
7. If the old ECM PN is known, proceed to step 10. If the old ECM PN is not known, proceed to step 8.
8. On the MDS2, select the "History" tab and select "General Information" at the bottom of the screen.
9. Under the "Equipment" window, identify and record:
a. Emissions (Federal or California)
b. Transmission (Automatic, 5-speed manual, 6-speed manual)
10. Select the "Flash" tab.
11. Select "Use Currently Selected Vehicle".
12. Select the proper calibration:
a. If the old ECM PN is known, locate and select the ECM calibration part number that corresponds to the old ECM part number.
b. If the old ECM PN is not known, select the correct calibration based on the information that was recorded from "Vehicle History".
13. Select "Update Controller Software".
14. Monitor the "Status" window on MDS2 and follow the instructions.
15. Follow the instructions on the DRBIII to complete the calibration download process.
16. For 2003 and later modules, determine if the vehicle is equipped with
a SKIM (Security Key Immobilizer Module) module.
a. If the vehicle is equipped with SKIM, the DRBIII must be used to transfer the VIN and Security Key from the SKIM to the ECM. This is accomplished by selecting "Cummins ECM Replaced" under the "Miscellaneous" section of the "SKIM" menu.
b. If the vehicle is not equipped with SKIM, the VIN must be manually programmed by selecting "CM845 Check VIN" under the "Miscellaneous" section of the "Cummins Controller (ECM/ENGINE)" menu."
NOTE: ALL OTHER NORMAL REPROGRAMMING (FLASH) PROCEDURES, AND AFFIXING SOFTWARE UPDATE AND MODIFICATION LABELS, MUST STILL BE FOLLOWED WHEN INITIALLY PROGRAMMING THESE MODULES.
There are three (3) part numbers available for order, based on Model Year of vehicle.
