adding wheel controls 2014 silverado

Post by kpetz » Sun Aug 06, 2017 11:01 pm

Hello.

I purchased the Maestro RR and GM3 to interface my new Kenwood DDX6903S stereo that I installed in my 2014 Chevy Silverado. The interface to the trucks systems works great. Getting all that extra data and features was well worth it. The one thing that I wanted to add, that I don’t have now, is steering wheel controls of the radio and phone. The wheel at present only has the cruise control buttons. I purchased a used wheel from E-bay. Unfortunately, I installed it today and it does not work. There is only 3 wires needed for this to work. Power, ground and data bus. I verified the power is present. Verified that the data bus wire has continuity from the buttons on the wheel to the Maestro RR. I would thing this should work even though the truck did not have this option. I even cut the wire for the data bus going into the truck’s harness so it only goes to the Maestro RR but this made no difference. I updated the firmware in the stereo and Maestro to no avail. I also need to consider the possibility that the wheel is defective?

Do you have any suggestions or opinion on this.

If the truck doesn't have OEM steering wheel controls, I believe they have to be activated by the dealer by flashing the BCM. As far as I have been told, most dealers are not willing to do this.

My thinking is that the old stereo is gone. I have the Kenwood with the Maestro RR. The Maestro is the bridge between the wheel controls and the Kenwood. The BCM is out of the picture. This should work. I'm missing something.

Yes, you are missing something- the steering wheel controls are on the lin bus, a data line. The vehicle's computers need to be programmed to know that there are steering wheel controls in order for them to function. Right now, they're not, so they are not communicating on the data lines for the maestro to read them and make them work.

One thing I learned in the 40 years of being an industrial electrician is that engineers make things overly complicated,this being a good example. So I'm taking a new approach. I'm going to apply the KISS method. I will order the SW module and convert my push buttons on the wheel to the resistor system and that should work.

Hi, So I bought the Maestro SW module. Does the module reference to ground or + 12 VDC through the steering wheel resistors. In other words does the resistors in the wheel go to ground to +12 VDC.

Thank you

The most common way most steering wheel circuits are built is with a negative feed, so that's how ours reads.
