  You can read the fault codes in the security module but you will have to have the appropriate scanner for that. Many shops have that capability. Maybe you can just have them read the code for you. I do see a bunch of problems in a database I reference for information about the fuel guages (and speedometers) becoming failed, but the reason is very specific. It seems that if you have the battery disconnected (lets say that you got a new battery) and when you reattach the battery cables, if someone has left the ignition key in the on position it results in a voltage spike that can cause the fuel gauge and often the speedometer needle too to "jump" completely around past the full mark and stop "under" the empty mark. And, the fix is to take like a paper clip and insert it in through the set knob for the trip meter and reset the needle by rotating it counterclockwise. This does not seem to be related to a security light though.
