Overview:
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (Cummins PCM) with new software.

Symptom/Condition:
The customer may experience the illumination of the "Check Gauges" lamp on the

          P2503 - Charging System Output Low - Diesel
          P2509 - Powerdown Data Lost Error - Diesel

Diagnosis:
Using a Scan Tool (StarSCAN) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTCs are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.

If the vehicle operator describes or experiences the Symptom/Condition, perform the
Repair Procedure.

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. 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.dectools.com website under
the "Download Center".

to perform the Repair Procedure, or use the StarMOBILE, in its CONNECTED made
to perform the Repair Procedure.

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

1.	Open the hood and install a battery charger. Using a voltmeter, verify that the charging rate provides 13.2 - 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.
NOTE: Do not allow the charging voltage to climb above 13.5 volts during the flash process.

17.	Verify the part number at the top of the "Flash PCM" screen has updated to the new part number.
18.	The Wireless Control Module (WCM) requires updating of the Secret Key information using the PIN information obtained earlier. From the StarScan Home Menu:     a. Select "ECU View"     b. Select "WCM".     c. Select "Miscellaneous Functions"'.     d. Select "PCM Replace".     e. Follow the on-screen prompts to complete the updating process.
