What kind of Fuse is the IoD fuse?
The IOD fuse is a standard 15 amp blade fuse; there’s a diagram on the inside of the IPM lid showing the fuse positions. The fuse pulls straight up and out – no tabs or anything to release to remove it – and reinserts the same way.
Where is the IoD fuse on a minivan?

How many milliamperes does a low amperage IoD need?
The low-amperage IOD should not exceed twenty-five milliamperes (0.025 ampere). If the current draw exceeds twenty-five milliamperes, isolate each circuit using the fuse and circuit breaker remove-and-replace process in step 4.
