Abstract

A vehicle may include a body controller programmed to limit operation of at least one vehicle feature to reduce battery consumption during transit of the vehicle in response to a vehicle flag indicating a transport status, and to enable operation of the at least one vehicle feature during manufacturing in response to the vehicle flag indicating a factory status.

Claims

1. A vehicle comprising:

a body controller programmed to limit operation of at least one vehicle feature to reduce battery consumption during transit of the vehicle in response to a vehicle flag indicating a transport status, and to enable operation of the at least one vehicle feature during manufacturing in response to the vehicle flag indicating a factory status, wherein limiting operation of the feature includes slowing response sampling associated with the feature.

2. The vehicle of claim 1, wherein the body controller is further programmed to receive an ignition status, and to limit or enable the operation of the at least one vehicle feature in response to receiving an off ignition status.

3. The vehicle of claim 1, wherein limiting operation of the at least one vehicle feature includes disabling the at least one vehicle feature.

4. A vehicle comprising:

a body controller programmed to receive a life cycle indicator and at least one other factor and to limit or enable at least one vehicle feature based on the life cycle indicator and at least one other factor, the at least one other factor including at least one of a time since vehicle key-off and a battery status, wherein limiting the at least one vehicle feature includes slowing response sampling associated with the at least one feature.

5. The vehicle of claim 4, wherein limiting the at least one vehicle feature includes disabling the at least one vehicle feature to reduce battery load.

6. The vehicle of claim 4, wherein the at least one vehicle feature includes at least one of a delayed accessory, approach detection, passive entry and tire pressure monitoring.

7. A vehicle comprising:

a body controller programmed to limit operation of at least one vehicle feature in response to a vehicle flag indicating a manufacture status and to enable the at least one vehicle feature in response to the vehicle flag indicating a consumer status, wherein limiting operation of the at least one vehicle feature includes slowing response sampling associated with the at least one feature.

8. The vehicle of claim 7, wherein the body controller is further programmed to receive an ignition status, and to limit or enable the at least one vehicle feature in response to receiving an off ignition status.

9. The vehicle of claim 7, wherein limiting operation of the at least one vehicle feature includes disabling the at least one feature.

10. The vehicle of claim 7, wherein the manufacture status indicates that the vehicle is one of in transit or in production.
