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.
