Vehicle having a diagnostic system for an electrical fuse

A vehicle having a diagnostic system for an electrical fuse, comprising:

• a first voltage sensor generating a first signal indicating a first voltage level at a first end of the electrical fuse;
• a second voltage sensor generating a second signal indicating a second voltage level at a second end of the electrical fuse;
• a current sensor generating a third signal indicating an amount of electrical current flowing through the electrical fuse;
• a microcontroller determining first and second voltage values based on the first and second signals, respectively, and a current value based on the third signal;
• the microcontroller determining a first resistance value of the electrical fuse utilizing the first and second voltage values, and the current value;
• the microcontroller retrieving a first stored resistance value associated with the electrical fuse from a plurality of resistance values in a table, utilizing the current value as an index to the table;
• the microcontroller multiplying the first stored resistance value by a first value to obtain an end-of-life resistance value;
• the microcontroller generating a first diagnostic signal indicating degraded operation of the electrical fuse if the first resistance value is greater than or equal to the end-of-life resistance value;
• and
• a vehicle controller operably communicating with the microcontroller, the vehicle controller receiving the first diagnostic signal and generating a fuse servicing message that is displayed on a vehicle display device in response to the first diagnostic signal.
