The dealerships are generally clueless on this kind of thing, it likely has to do with the safety connect service, Toyota's version of Onstar.

 

Did you receive an explanation? My Avalon is doing the same thing.

 

"When I take it to the dealership they tell me they have no idea why it does it, but tells me to not worry about it..."

OK, maybe it's just me, but if I got the 'they have no idea' answer, I'd go ballistic and ask to speak to the Service Manager and tell them to get Toyota Technical Support on the phone immediately and wouldn't leave until I had the answer. Completely, totally unacceptable in my opinion.

 

It doesn’t sound like this causes any real problems other than a brief, minor annoyance. Toyota Service should have a good answer and correct it, sure, but I can’t imagine making a big stink over it.

 

When ANY technical support/service department responds 'they have no idea'? That's precisely when to make a 'big stink'...It's their entire job description and mission to know or escalate to someone that does, or what's the point of having a service department for any electronic product and but especially for a top of the line model of Toyota? Do you think Samsung or LG can get away with that answer when servicing a $1,600 washing machine? 'We don't know why it does what it does?...' You can't do your family's dirty laundry...that's literally 'a big stink'...

 

“Communication Module Activation Complete”.

There's the message. There's nothing to 'reproduce' or 'troubleshoot'. Toyota Corporate Software Technical Support should be able to immediately know thru a search of their 'knowledge database' what is the cause of that single message.

 

For what it's worth, first hit on Google went to Reddit, looks like it could be related to the Dynamic navigation function on the premium audio?



Toyota CH-R Service Manual https://www.tochr.net/371/system_description.html says this is a part of the Safety Connect System. It describes

"Safety Connect performs ACN (Automatic Collision Notification), manual emergency calling, stolen vehicle tracking and roadside assistance service by, audio and data communications between the vehicle and call center through a cellular phone network. As shown in the illustration, when a collision is detected, the vehicle sends its location calculated based on GPS signals and the identification code of the DCM (Telematics Transceiver) to a call center. After the necessary information has been gathered, the call center will relay this information to emergency services. "

They talk about a " Voice Guidance Function", which, among other things, says “Communication Module Activation Complete” if/when "DCM Activation completed successfully."

I'd tap the SOS button and ask the rep who responds.

 

I would still ignore it. I have neither the time nor energy to demand answers to small stuff like this.

Call me silly. I can take it.

Lol. Sorry. I meant I thought the situation is silly, not you. Didn't mean to make it sound personal.

 

Ha, ha, these forums are open to all. I’ll speak when I want to! (And I’ll always keep it respectful and courteous).

[Edit: Thank you, forum, for taking action on and deleting the earlier comment that prompted this message. I do appreciate it. Mutual respect is what we all deserve!]

This thread has really, really inspired me, so I'm going to start troubleshooting all the positive responses and successful completions I experience in the future. Heck, I'm retired, it can help fill out my days.
