Reason For Update

NOTICE
DO NOT diagnose or replace any components for the above fault(s) before performing the update function
as explained in this bulletin.

Technical Background
Updated ECM software to improve thermostat performance.

Production Solution
Improved ECM software implemented in production.

Service
Update-Programming Procedure:
WARNING
Critical Warning: The Midtronics battery charger with at least 70A charging current 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.

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 objects away from Radiator Fan(s) during update process.

NOTICE
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 # VHW-22-13. 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/X 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.

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.
