I had my security module replaced 2 times. Well, when I checked the work orders, it was a different part number both times.
The first one they replaced was 1S4Z-15K600-CC, and the second one they replaced was 1S4Z-15K600-JC. Where are these boxes located, and secondly, why would they both fail about a week apart. The first one caused problems when I armed my car, the lights wouldnt flash. The second module caused problems when I braked, my brake lights would not illuminate. I hope the problems are fixed for good.

Reason for failure:
You have two completely different part numbers
listed for two different applications.
If the EXACT correct part isn't ordered,
you will encounter all sorts of strange electrical
problems...If you still have problems, you may still
not have the correct module for your car.
