01-23-03 Update Programming, DTC P2407 Stored in Engine/Motor
Control Module -J623-

Transaction No:

2069659/2

Release date:

6/27/2023

Technical Background
Current engine software may allow erroneous faults to be stored in ECM memory.
Note:
Current engine software may incorrectly store a P0442 DTC instead of a P2450 DTC due to the
calibration of the diagnostic.

Production Solution
Introduced improved engine software in production.

Service
Update-Programming Procedure:
Critical Warning: : The Midtronics battery charger must be connected to the vehicle battery for the
duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the
update process. If the battery drops below 12.5 volts, the programming could fail which may result in
damage to the control module. Control modules damaged by inadequate voltage will not be covered
under the warranty policy. The technician should verify the vehicle voltage prior to starting the update
process, and should monitor the voltage for the duration of the update.
The procedure may cancel itself if the hazard warning lights are not switched ON. The hazard warning
lights prevent the system from switching to bus sleep mode during the update.
ODIS-Service tester should be updated to the latest GFF technical version 11.0.0 or higher and SW
version 2.47.0 or higher.

WARNING:
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a risk that personal
injury may result if contact is made with spinning fan blades.
Keep hands and all objects away from Radiator Fan(s) during Update Process!

Control Module -J623-

Note:
Prior to launching the ODIS Service diagnostic applications and starting control module update process,
confirm tester screen saver and power settings in accordance with Diagnostic Device Hardware &
Windows® - VHW-20-02 Change Power Options After Windows®10 Upgrade. Failure to do so may result
in the tester entering power save mode during data transfer, and subsequent control module failure.
When using a VAS 6150/X or 6160/X tester in conjunction with a VAS 6154 wireless transmitter head for
a flash procedure, connect a USB cable between the transmitter head and the tester. Failure to do so
may lead to errors during the flash procedure.
VAS tools must only be used with their power adapters plugged in. Under no circumstances should they
be used on battery power alone during the programming procedure.
Tip:
To Update-Programming using Software Version Management (SVM), review and follow instructions in
Technical Bulletin Instance 2014603 “Software Version Management”.
The SVM process must be completed in its entirety so the database receives the update confirmation
response. A warranty claim may not be reimbursed if there is no confirmation response to support the
claim or action is carried out that is not explicitly stated in the Technical Bulletin.
 Update the Engine Control Module using the SVM Unit code as listed in the table below:
