2011 Sequoia, factory amp, no subwoofer sound

Post by AmazinglySmooth » Sat Sep 08, 2018 9:47 am

Using the factory amp and the Maestro Rr, I don't seem to be getting sound from the amp. How can I test it?

2011 Sequoia, factory satellite, text not updating

I'm using the Rr to retain the factory satellite feature of my Sequoia. The audio works fine, but the text displayed for the channels isn't being updated properly. When I select a preset the channel name and number and song title all update, but the artist is from the previous channel.

So, it seems intermittent. Over the weekend, I played with it many times. The audio would be present and then cutoff unexpectedly. It would then return. When no audio was present, sometimes the Amp Settings were visible and sometimes greyed out. This morning the steering wheel controls and factory satellite radio were not working. I restarted the vehicle and then all features were working.

Hardware or firmware issue?

I'd say it sounds like a connection issue. On your t-harness, there is a white 2-pin plug with green/red and green/yellow wires in it. Make sure those are seated VERY well (these are the data lines where the amp is detected and controlled). If those wires have a poor connection at any junction, it could cause you to lose sound, and losing those menus tells us that's the most likely culprit.

I merged your posts together; there is no need to have two topics for one vehicle.

I will check with engineering and see if we have seen this issue before. What radio are you using?

I should add that these problems are intermittent but in an unusual way. The sound would work for 30 minutes or more and then cut out. Most of the time things would return after a restart, but once it returned on its own after about 20 minutes. The satellite radio drop only happened once and recovered after restarting. I don't get any static or other indication.
