lack of audible tone for keyless entry

[Shroomster]

I was looking at a yaris LE today at work and hooked it up to our techstream. I wanted to see if maybe the dealership/factory forgot to set our keyless entry up. Well they didn't. I couldn't find anything in any of the modules or even under customization options, to add a beep for lock and 2 beeps for unlock. Why did they cut that feature from this car? Wife gets paranoid thinking she didn't lock the car, cuz she didn't hear a beep.

It's light flash only for the 2012 with remote locking. With it all being CAN based, you can't even grab the output from the keyless entry system to make it beep something else.

Maybe I should create a CAN lock beeper for you 2012 people.

I just need to get my hands on a 2012 to sniff the CAN bus messages to see if body ECU ones are the same as for the prior generation.

While you're checking the code out, I wonder if you can see if the flashing can be turned off during locking and unlocking activities. I would prefer not to have any signs at all.

Many thanks.

For the 2012's here are the "customize parameters" via TechStream:

Wireless Control - Function that turns wireless door lock / OFF or ON

Hazard Answer Back - When the doors are locked by wireless operation, the hazard warning lights flash once.
When the doors are unlocked by wireless operation, the hazard warning lights flash twice.

Unlock 2 Operation - Function that unlocks driver door when unlock switch on door control transmitter module set sub-assembly is pressed once, and unlocks all doors when pressed twice. If setting is OFF, pressing unlock switch once makes all doors unlock.

Panic Function - Function to operate theft deterrent system by continuously pressing panic switch on door control transmitter module set sub-assembly for 0.8 seconds

Auto Lock Time - (30, 60, or 120 s) Function that regulates the interval between unlocking and automatic relocking of doors

Wireless Auto Lock - This function turns the wireless auto lock function on or off.

Referencing ctscotts post, in techstream customize menu, you would want the hazard answer back turned off.....

Thanks for the keyword "hazard answer back", I was able to search the relevant thread.

So I guess I've to visit my dealer to perform this change, and there is no DIY method available for the MY2012.

JMO but I like it better without the beep(s).

Anyway to turn off the horn honk with keyless entry on a 2011 Sedan?

My mom had the car not quite in "P" and in panic when she couldn't restart the car, started pushing all sorts of buttons and somehow activated the horn sound on the keyless entry.

I just need to get my hands on someones 2012+ for a few minutes to verify the CAN bus message.
