1. A maintenance device for a vehicle system, the maintenance device comprising:
- a sensor configured to measure a measurable characteristic of the vehicle system, and to transmit a sensor signal indicative of the measured value of the measurable characteristic;
an electronic control unit configured to receive the sensor signal and to generate data representative of the measured value of the measurable characteristic, and to selectively transmit said data in response to one or more predefined prompts;
a recorder module adapted to receive the selectively transmitted data and to transfer the data in a convenient manner such that vehicle operation can be evaluated remotely from the vehicle; and
a power supply circuit adapted to temporarily power the recorder module after the vehicle has been turned off such that any data that has not been transferred may be preserved, and thereafter the power supply circuit is configured to power-down the recorder module such that energy is conserved while the vehicle is off.

Abstract
A maintenance system for a vehicle including a component or system having a measurable characteristic is provided. The maintenance system monitors, stores and/or transmits data representative of the operation of the component or system, whereby the transmitted data may be analyzed and vehicle performance improved through the analysis thereof.

11. A maintenance device for a vehicle system, the maintenance device comprising:
-
a sensor configured to measure a measurable characteristic of the vehicle system, and to transmit a sensor signal indicative of the measured value of the measurable characteristic;
an electronic control unit configured to receive the sensor signal and to generate data representative of the measured value of the measurable characteristic, and to selectively transmit said data in response to one or more predefined prompts;
a recorder module adapted to receive the selectively transmitted data and to transfer the data in a convenient manner such that vehicle operation can be evaluated remotely from the vehicle;
a global positioning system adapted to provide the analyst the location of the vehicle; and
a power supply circuit adapted to temporarily power the recorder module after the vehicle has been turned off such that any data that has not been transferred may be preserved, and thereafter the power supply circuit is configured to power-down the recorder module such that energy is conserved while the vehicle is off. - View Dependent Claims (12, 13, 14)

15. A method for monitoring a vehicle system, the method comprising:
-
measuring a measurable characteristic of the vehicle system;
generating data representative of the measured value of the measurable characteristic;
selectively transmitting said data to a recorder module in response to one or more predefined prompts;
transferring said selectively transmitted data in a convenient manner such that vehicle operation can be evaluated remotely from the vehicle;
supplying power to said recorder module after the vehicle has been turned off such that any data that has not been transferred may be preserved; and
powering-down said recorder module after said data has been preserved such that energy is conserved while the vehicle is off. - View Dependent Claims (16, 17, 18)
