Summary
Important: This technical service bulletin (TSB) can only be completed by certified repair facilities who have met all
specific training, tool and equipment requirements pertaining to the vehicle Brand and Model serviced. Repairs must
be performed by a technician who has successfully completed the required training.
Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws
applicable to the activities it performs under this bulletin, including but not limited to handling, deploying,
preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a
conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you
must follow those applicable laws.
Transport Mode Feature, also known as Logistics mode, is used to increase the 12V Battery stand time of the
vehicle during transit and or long period of stand time at the dealerships. It is used to put modules on the vehicle into
a low power mode, reducing the electrical parasitic load on the battery when the vehicle is standing for long period of
time. In this mode, stand time can be extended up to 70 days by reducing vehicle drain down to as low as 10 mA
depending on vehicle and content.
Important: Vehicles that are shipped from the assembly plant with Transport Mode On, turning the feature Off into
Customer Mode is included in the normal PDI process time. No additional warranty claims should be submitted to
disable or enable this feature.
The modules that participate in Transport Mode are the Body Control Module (BCM), Radio, Front Camera Module,
Running Boards, Onstar, HVAC, Rear Wheel Steering Control Module and more to come in the future. The major
contributor to transport mode is the BCM; it shortens the Retained Accessory Power (RAP) time down to 1 minute,
disables Approach Detection, eye catching lighting features, comfort features like heated seats and steering wheel,
etc.
Some other features that are disabled in Transport mode if equipped are:
• HVAC and Radio features (Ignition Off)
• Passive and remote keyless entry
• Perimeter lighting

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
