Default Honk the horn, zr4 goes off

I have a zr4 system installed and powering a 9500ix in a 2007 Corvette. If my engine is around 1000 rpms and i honk the horn, the zr4 goes off saying shift sent. What's up with that?

EMI..........Electromagnetic interference.

The transformer in your Vette's horn puts out a huge magnetic field that induces noise into the wire leading to your shifter which is setting a false alert.

Possible solutions.

#1. Check the routing of your shifter wires. If they run near the horn try re-routing them away from it.

#2. Check the ground connections on the 9500ci's controller box and on the car horn. Make sure both are solid connections (tight) and that there is no corrosion where the ground connects to chassis (bare metal).

#3. If correcting problems found in 1 & 2 above don't help, then get yourself a couple ferrite (iron) chokes (aka. torroids) from radio shack and place them on the shifter wires leading into the controller box. You wrap the shifter wires 2 or three turns around and through the center of these metal donuts (chokes) and that should filter out the noise being induced into the wire by the horn.
