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
• Automatic running boards
• Liftgate or tailgate
• eTrunk (if equipped)
• Active safety features
• Charging above approximately 30% (program
specific value)

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.
