01-24-04 - Update Programming DTC P148D Stored in Engine/Motor
Control Module -J623-

Transaction No:

2073713/1

Release date:

4/30/2024

Technical Background
Updated programming of the Engine/Motor Control Module -J623- (ECM) software is based on most
recent engineering experiences and makes this knowledge available for the monitoring strategies.

Production Solution
Updated Engine/Motor Control Module -J623- (ECM) software introduced in Model Year 2022 Production.

Service
Update-Programming Procedure:
Critical Warning: The VAS5908KIT 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 24.0.1 or higher and SW
version 2.49.18 or higher.

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 blades. Keep hands and all objects
away from the Radiator Fan(s) during the update process!

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-22-13 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
VAS6154A 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
