Condition

Update Programming Electromechanical Steering Gear
A pulling sensation may be perceived in the steering wheel while driving on flat roads. Be aware that road crown
can have a significant impact on the customer’s perception of a pulling sensation while driving.
Note:
This bulletin only applies to vehicles with an electromechanical steering rack.
This update should be performed before any additional repairs are made to the vehicle; such as TSB 2031087 for
selective tire placement or a vehicle alignment.
The condition of the vehicle should be re-evaluated after the programming update to determine if additional
diagnosis is necessary.

Technical Background
A new software map for the power steering control module was developed to reduce the retention force necessary
to keep the vehicle driving straight ahead.
Note:
Be aware that vehicles tend to follow the natural crown of the road. Road crown can have a significant impact on
the customer’s perception of the pulling sensation while driving.

Service
Update-Programming Procedure:
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 Special Tools and Equipment - Service Information
Circular # VVT-12-02. 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 5054A wireless transmitter head for a flash
procedure, please 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.
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.
Step 1
To perform the procedure click on the control module tab in the upper left hand portion of the screen once all
control modules have been identified.
