Device and method for detecting faults in electronic systems
First Claim
1. A fault detection device for detecting faults in an electrical system comprising at least one electrical control unit electrically connected to a plurality of electrical components, said fault detection device comprising:
- a first measuring unit configured to receive, from said electrical control unit, a first error value indicative of a fault in a subset comprising at least two of said plurality of electrical components;
a communication unit configured to provide information to a user interface;
a second measuring unit configured to be electrically connected directly and simultaneously to each of said at least two of said plurality of electrical components in said subset during a measurement; and
a processing unit connected to and configured to control said first measuring unit, said second measuring unit, and said communication unit,wherein said second measuring unit is configured to, based on said first error value indicative of a fault in said subset, determine an operational status of each of said electrical components in said subset of electrical components, andwherein, said communication unit is configured to provide, to said user interface, an indication of said operational status.

Abstract
A device and a method for detecting faults in an electrical system. The fault detection device includes, a first measuring unit configured to receive a first error value indicative of a fault in a subset of a plurality of components, a communication unit configured to provide information to a user interface, a second measuring unit configured to be electrically connected directly to each of at least two of the plurality of components, and a processing unit connected to and configured to control the first measuring unit, the second measuring unit, and the communication unit. The second measuring unit is configured to, based on the first error value, determine a operational status of each of the components in the subset.
