where is ecu located on 1999 cummins
« on: March 6, 2011, 09:42:46 AM »
Howdy, I have a 1999 RAM 3500 with a cummins 4x4 auto. I need to replace ecu/ecm. I believe its located on floor under stereo ac controls behind cover with 2 screws. Is this or is it some where else. What is all entailed with replacement. Some one said it hastily be bin flashed and I saw an online computer exchange that said they can send me a pre flashed unit with my bin number. If this is case is it a simple plug n play. Plus theirs is only 650 whereas dealer is 2000. Any all help appreciated! Thanks, have good day..

The Engine Control Module (ECM) is bolted to the left side of the engine behind the fuel filter.
Now according to TSB# 18-033-04, they have phased out pre-programmed ECM's. Meaning it would have to be programmed after installation.

 Maybe the dealer near you has some left that are programmed? Or you know of an independant that has the capability of programming.

THIS BULLETIN SUPERSEDES SERVICE BULLETIN 18-030-03 REV. A DATED OCTOBER 17, 2003, WHICH SHOULD BE REMOVED FROM YOUR FILES.

THE DRBIII FLASH FILES FOR THIS BULLETIN ARE AVAILABLE ON DealerCONNECT.

FOR MARKETS OUTSIDE OF THE UNITED STATES AND CANADA, THE FLASH FILES AND REPROGRAMMING INSTRUCTIONS WILL BE AVAILABLE ON ITIL/ISIS DVD OCTOBER, 2004.

Models: 1998.5-2005 (BR/BE, DH/DR) Ram Truck

1998 1/2 - 2002 (BE/BR) Ram Truck
2003 - 2005       (DH/DR) Ram Truck

NOTE: This bulletin applies to all ram trucks equipped with the 5.9L Cummins 24-valve diesel engine (sales codes ETC or ETH).

Overview:
This bulletin involves programming a generic Cummins ECM with software

Discussion:
Mopar is 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 TechCONNECT. 1998 1/2 - 2002 modules will cause the "Wait to Start" light to flash, indicating the module has not been programmed.

CAUTION: Extreme care must be taken when changing the calibration of an unprogrammed ECM. Do not randomly select a calibration. If in doubt, contact the STAR Center for assistance. Installing an incorrect calibration into an ECM can cause severe engine damage. Once a calibration version is selected and programmed, the controller cannot be reprogrammed to a different calibration. The module can only be reprogrammed to a more recent version of the same released calibration.

a.       Simultaneously press the "MORE" and "YES" keys.
b.    A screen will appear requesting a "COLD BOOT".
c.    Follow the on screen instructions by selecting the "F4" key.
d.    the DRBIII reboots to the MAIN MENU, proceed to Step #2
2.         With the ignition switch in the "RUN" position, determine and record the ECM part number of the ECM currently in the vehicle. Using the DRBIII select.
a.       "DRBIII Standalone"
b.    "1998 - 2005 Diagnostics"
c.    "All (Except Below)"
d.    "Engine"
e.    On 1998 1/2 - 2003 vehicles, select "Cummins". 2004 and later vehicles, proceed to next step.
f.    "Module Display"
g.    Record the "ECM part number, on the repair order for later reference.
NOTE: If the ECM is not operational, the "ECM part number" can be obtained from the label on the controller. For 1998 1/2 - 2002 vehicles, if the label on the controller is not legible, proceed to next step. For 2003 and later vehicles, 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 below. The Engine Data Plate is located on the intake side of the breather cover or affixed to the APPS bracket.
