CTSHO005.2 Honda Steering Wheel Stalk Control Adaptor

This is another adapter example that you may need to connect aftermarket audio to wheel buttons and some more signals (dash light, reverse, parking brake, etc).

Link to http://www.ebay.com/itm/370765327954 - 39 GBP + 12 GBP (delivery).

This is a patch lead, PDF is here.

In default configuration it works as follows: it outputs resistance change depends on button pressed.
These are readings on KEY1 wire

Idle (nothing pressed)	11.5 MOhm 189 kOhm (after 1st time pressed)
Volume Down	22.00 kOhm
Volume Up	16.43 kOhm
Seek Backward	11.82 kOhm
Seek Forward	8.58 kOhm
Middle (circle button)	2.07 kOhm

I believe, you can change to voltage too just follow the instructions.

This is an adapter doc, PDF is here.

Wiring for Civic connectors.

Note that ACC signal is taken from 2nd connector both with CAN bus.

Let's open this sucker.

Main ICs are:
NXP TJA1040 - High speed CAN transceiver
Renesas Eelectronics R5F2123 - R8C Series 16 bit 3 kB RAM 64 kB Flash Microcontroller SMT
Fairchild FDS4953 - Dual 30V P-Channel PowerTrench MOSFET

Little man says hi!

Standby consumption.
When you first plug it, it will drain about 25-30mA for a few seconds and than falls into 3mA even when you send 12V to ACC.

The only addition I've made is adding original Honda's AUX 3 wires (on right) to it.

Honda Steering Wheel Stalk Control Adaptor from Teder

This is an adapter from my Civic they local dealers put for aftermarket multimedia units like my prev Blaupunkt New York 830 works with buttons on steering wheel.

Why you need that?
Because on modern cars, all communication done via CAN bus. Same on most late Hondas. All buttons signals going into CAN and most of aftermarket units (Pioneer, Alpine, Clarion, etc) not have CAN module to decode that signals. So you need an adapter.

How it works?
This one works with voltage change. Other units works with resistance change.

These are readings on ORANGE wire that my adapter outputs

Idle (nothing pressed)	4.933 V
Volume Down	3.946 V
Volume Up	3.353 V
Seek Forward	2.735 V
Seek Backward	2.145 V
Middle (circle button)	1.575 V

Label on the unit says:
Teder Audio
Honda Civic
Hardware version 1.00
Software version 1.07
Date 2013-06-04. I got my car 2013-07-04 - close enough.

Let's crack this sucker open!

Main ICs are:

CPU: STI STM32F103C8 - Mainstream Performance line, ARM Cortex-M3 MCU with 64 Kbytes Flash, 72 MHz CPU, motor control, USB and CAN.

CAN: Microchip MCP2551 - MCP2551 is a high-speed CAN transceiver.

Looks like this unit is made here in Israel by www.erm.co.il.

Below are Honda's main connectors.
Big one with power supply and speakers output.

Smaller one that has CAN bus, AUX in and ACC.

Browns are CAN, violet are AUX L+R in with green (GROUND for them).

Wiper Blades Rubbers Replacement

While I was waiting for technicians fix bluetooth in my Blaupunkt New York 830, I decided to replace wiper rubbers.
2 years is about time to replace. If you find cheaper than original and good quality (just look for proper length) - 1 year is reasonable period to change rubbers.

This is the old rubber insert from rear wiper.
It has little cracks and when I pulled it, the main cleaning part came apart from the rubber base.
Also interesting that on plastic holder you can see it says "450-550 L". Length was 450mm and probably it suitable for upto 550mm but you need to replace metal holders with longer ones.

Here are both: the new rubber on top and the old rubber below it.

If you look for details, you can see also production date that is important, because rubber gets dry by the time and you better get newest when you by and can check it.
You can see 2 digits of year ending 08, 09, etc and dots in between. Each dot represents 1 month.
So, new was produced somewhere after 2012, the photo is cutted.
The old was from 2011-03.

Blaupunkt Service Menu

Got this trick from Teder guys when they checked why Bluetooth module in my New York 830 is not working.

How to enter into service menu?
1. Press Menu on device button (top left).
2. Press Setting icon on screen.
3. Now press DVD and than General icons, repeat this action 5 times.

Here is a short how-to video

And screens you will see.

Blaupunkt Failed Bluetooth Module Replacement

As I said before, bluetooth module stop working on mine Blaupunkt New York 830. Firmware upgrade didn't helped.

To check what is the problem, I was need to go to Tel Aviv visit Teder, the company that in charge for Honda, Volvo, Jaguar electronic installs and maintenance/warranty in Israel. Because local dealer can only take apart multimedia system and send to them. I decided that I will go by myself, eventually I go to TLV once a month or so. And we talked with Amikam, man from Teder I've met in Honda's Netanya that came sometimes to fix owner's issues (you need to schedule with garage when he comes).

I went there too early cause I don't like traffic jams that we have towards TLV (aka center) each working day at morning. I was there around 7:30, they opened at 8:30.

We opened a case.

They tried again to fix with firmware upgrade. Exactly the same version that Amikam tried in Netanya. Surprisingly... no luck, no bluetooth working.

And they decided to get unit out and replace bluetooth module.
There is a good practice to take pictures of "working area" in Honda before they start working on it.

Unit is out.

So I waited for about 1 hour and decided to go for my other thing I planned in Tel Aviv.
Just as I left them, I got a call in 2 minutes that unit is ready and everything is working. I came back in 30 minutes and I had no time for installation back, so I told that we gonna connect wire harness and see it working and I will put it back by myself with no rush.

We checked and bluetooth indeed was working now.
This is software info as they installed.

But... as I found later, they damaged volume knob!
I hope you can see scratches. It was like new before repair. I guess it was laid on table on unit's front and moved back and forth...

WHYYYY? Not surprised anymore :-) It's how you service in Israel, Honda doesn't cares...

Later, starting using my phone again via bluetooth, I've found that it not always connected when you start vehicle. When It happens, it shows this screen while in bluetooth menu and does nothing.

XPRAM Downloading Upgrading

I'll try to contact them again or maybe another try for firmware upgrade.
