I don't understand your apprehension.
Any car with computers and remote entry will light the bulb in your test, you still have to know the current draw to prove there is an issue or not. I lost track of the number of times since 1980 that some mechanic somewhere told me my communication gear “lit the test light” and wanted me to fix what they thought was broke. I used a meter and all read in spec.
