So, I'm working on my on-going install of a D3 in my car. Everything is working, minus my steering wheel controls. I'm using the Peripheral PESWIPS adapter for Pioneer/Sony radios.

Everything is wired as described in the installation instructions, both online and in the booklet. The interface wire being used from the car's harness is pin 12 (brown/yellow) from the harness connector that has the speed pulse wire and both the ground wire for the box and another wire from the car's harness are grounded out.

The PESWIPS gets power, as it responds (light flashes on it) when you program the box for the mode the car needs (mode 3 on the PESWIPS per the instructions). However, when I try to program each of the steering wheel's functions, the light doesn't flash how the manual describes it responding. It's as if the box doesn't get a response from the car.

For example, to program it, you hold the program button on the box, the LED comes on. Let go of the button, hold the steering wheel button you are trying to program (volume up is the first one that needs to be done). The box's LED is supposed to go out once the command is learned from the wheel. It doesn't shut off, as if it is still waiting for a response from the vehicle.

Any ideas?

let me look at our tech website to see if there is any info on the svt wiring for the wheel controls... cant guarantee anything, but im still at work so might as well look

sorry man, ive got nada for you

Hmm I'm trying to think why it wouldn't work. If everything is wired up right then there shouldn't be any reason. I have the AVH-P4000DVD and i didn't even bother with the controls.

Next chance I get I'm going to get onto the signal wire from the car (pin 12, black/yellow) with a multimeter and see if I'm getting the signal at the wire when I hit the controls. I should be, as it worked with the stock deck. We'll see though I guess...

Thought I'd post a solution here, just in case someone else needs to do this down the road...

Turns out, by tapping into the signal wire for the steering wheel controls at the harness connector behind the radio, you lose enough of the signal for the PESWIPS to not understand it. Connecting to the signal wire underneath the steering wheel (where the harness comes down from the steering column) fixes the problem.
