Section D – Update Gateway Control Module Software
(this only applies to vehicles with criteria 01 that did not have the green LED illuminate after the
12V battery disconnect and reconnect procedure outlined in Section C)
CRITICAL REPAIR INFORMATION
STOP!
Operating mode “Diagnosis” will be used for this action. Some models will not allow the update to start after changing
the communication path to DoIP using operating mode “Flash.”
NOTE
Prior to launching the VAS Diagnostic Tester and starting an update, ensure the following conditions are met;
The ODIS software is completely up to date.
Refer to the “Alerts” section on ServiceNet home page for the current ODIS version.
The battery charger is connected to the vehicle battery and remains connected for the duration of the
software update.
•
Battery voltage must remain above 12.5 volts for the duration of the software update. Failure to do
so may cause the update to fail, which could result in damage to the control module. Control modules
damaged by insufficient voltage will not be covered.
The screen saver and power saving settings are off.
•
Failure to do so may result in the tester entering power save mode during the software update, which
could result in damage to the control module.
The VAS Diagnostic Tester is plugged in using the supplied power adapters.
•
Under no circumstances should the tester be used on battery power alone during the software
update. Failure to do so may result in the tester powering off during the update, which could result
in damage to the control module.
The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.
•
Performing a software update using a Bluetooth or WiFi connection increases the risk of losing
connection during the update, which could result in damage to the control module.
It also greatly increases the time required to perform the update. Requests for additional time or
parts will be denied if the GFF log shows the update was performed using Bluetooth or WiFi.
NOTE
•
All campaign software updates must be completed during a single, standalone ODIS Diagnostic Session.
You must fully complete this campaign and send all logs before beginning any other campaigns or
operations.
•
If there are any ODIS “Hot-Fix” patches installed, they must be removed from the scan tool before beginning
this operation. ODIS “Hot-Fix” patches may affect the update process.

WARNING
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a serious 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!
TIP
To Update-Programming using SVM, review and follow instructions in Technical Bulletin 2011732: Software
Version Management (SVM) Operating Instructions.
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.
TIP
As a best practice, customer presets should be documented prior to performing any update in the event these
settings are lost during the update.
•

NOTE
Vehicles with Battery Monitoring Control
Module -J367- and/or an EFB Battery:
When connecting the charger to the battery,
connect the positive cable to the positive terminal of
the battery and connect the negative cable to the
grounding lug on the chassis. DO NOT connect the
ground cable directly to negative terminal of the
battery.
•
Turn the hazards on.
CAUTION
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.
