  1. In case people don't know, cars have communication buses on them now. Pushing a button simply signals a module which sends a message to its control module. Something has happened to the cab control module (or equiv) which is telling the vehicle to send the honk message. Where the honk button is translated to a start engine message. The fix is likely either ground wiring issue or a new control module.

  2.  @dsikid3  You need to take it to a mechanic. There is a published procedure to diagnose. They check the connector, voltages, signals, and PIDS and pull error codes. This includes whatever is proper for the attached control module. Which in turn may include connections from it to other modules. Likewise, a good device may be able to pull error codes which simply explain the nature of the root error (don't hold breath; bad voltage or ground or open connection). But these days these are mechanic class electronic tools which can range up to several thousand dollars (though less expansive is available).

  3.  @RollerBaller  Yes. A reporter had his car driven into a tree xxx'ing him.

  5.  @diamonddotzip5678  The design change limits the amount of wiring in the vehicle. This way you only require a ground, power, and signal to devices to which you which to communicate. This means you don't need 12v or 24v at the ignition switch. You can use whatever voltage is useful and common for your signal bus and then only require 12v or 24v at the ignition relay and so on. There are a lot of advantages this route. But as you can see it's not without complexity and disadvantages of its own. The diagnostic modules you find monitor at least one of these buses and looks for PIDs. Even your dash now monitors these PIDs are messages like MPG, MPH, oil pressure and so on. All from a set of common wiring. As each device does not require its own set of wiring. In older cars a cable would run from the transmission. And tubing from the engine for oil pressure. Everything is a trade.

  6.  @greenturkey7398  Different car issue. But you are correct for that one.
