Abstract
In one aspect of the invention there is provided a device comprising electrical connector means adapted releasably to connect the device to an electrical circuit overload protection apparatus of a motor vehicle, the device comprising means for measuring an amount of electrical current flowing therethrough and means for outputting from the device a signal corresponding to the amount of electrical current flowing therethrough.
Claims15
A motor vehicle, comprising:
- a current measuring device comprising an electrical connector adapted to releasably connect the current measuring device to an electrical circuit overload protection apparatus of the motor vehicle, the electrical circuit overload protection apparatus being arranged to allow at least one current measuring device to be removably connected thereto, wherein the current measuring device is configured to measure an amount of electrical current flowing therethrough and
- a communications controller configured to output from the current measuring device a signal corresponding to the amount of electrical current flowing therethrough, the vehicle being configured to determine whether a vehicle communications signal indicative of an operational state of one or more components of a motor vehicle is erroneous in dependence on the signal corresponding to the amount of electrical current flowing through the current measuring device.
A method of testing a vehicle comprising:
- releasably connecting a current measuring device to an electrical circuit overload protection apparatus of a motor vehicle;
- measuring, via the current measuring device, an amount of electrical current flowing therethrough and outputting from the device a signal corresponding to the amount of electrical current measured;
- and
- determining whether a vehicle communications signal indicative of an operational state of one or more components of the motor vehicle is erroneous in dependence on the signal corresponding to the amount of electrical current flowing through the current measuring device.
