[sr3jan]

If you just disconnect this module will the truck still run?

Wondering.... Could I change the pedestrian warning sounds?

I picked up a spare to play with via ebay.... This is located under the glove box.

Pretty simple device, 6 wires in and out. Power, Ground, CANBUS high and low and a speaker.

Cracked it open and identified the chips..

ARM processor, Amp chip on one side:

Op Amp, Line Driver and Flash memory on the bottom.

Dumped the Flash chip and low and behold... Our truck sounds.

Interestingly how they did it...

The Left Channel is the running sound.

While the Right Channel is the backup sound.

Which sounds like this:
(Couldn't upload audio files here.... so converted them to blank videos).

Backing up (Left Channel)

Driving (Right Channel)

You could get rich by locating and disabling all of the goofy noises / sounds mytruck make. silence is golden.

Since the sounds are on the chip, if you can just re-flash the chip to make them blank (to not cause errors) or something else might be better.

If we can reprogram it, maybe get "ED-209" to voice a warning - "Step away from the Lightning...you have 20 seconds to comply"

Or the classic... "This is Viper, stand back"

Amazing work. Unsure your truck does, love to hear the fix. When my spouse riding with me I get directions even though I put nothing in the navigation system,.
