OBD2 connector
on: September 10, 2018, 09:47:28 PM
Hello,

So in my quest to remove the CA compliance system in my Z900 (found at https://www.z900forum.com/index.php/topic,1862.0.html), I purchased an OBD2 adapter for the bike from https://www.woolichracing.com/products/kawasaki/z900/2017/964/kawasaki-obd2-harness-type-3.aspx

Taking a look, it seems that this may just be a basic cable that you could make at home. While I have not tried the following, here is the pinout I have mapped on the device.

on the OBD2 connector side:



P4 & P5 - GND
P7 - DATA (K-Line)
P16 - 12v

On the 6 pin Kawasaki side:


P3 - DATA (K-Line)
P5 - 12v
P6 - GND

For specifics, the bikes seem to use the ISO14230 KWP2000 protocol.

I checked for resistance and did not find any on any of the 3 pins, but I also can't see inside the OBD2 connector port of this cable to verify their isn't any protection circuitry. Hopefully this information can help others out, or at least be a start for home-made cheap cables.

You are probably referencing in the other post when I asked if you could measure resistance/continuity. I said "resistance" because ZERO ohms is continuity. They don't use any circuit or resistor on the OBD2 side of the connector...its a simple pass-through design.

Yep that was it. Also as an update, I went ahead and purchased this OBD2 code reader, and can confirm it works great with the bike.

ALSO, I marked the kawasaki plugs incorrectly and I can't edit the post.  :003:

If the adapter pins map to as follows, where bold is the wires you see:

1 2 3
4 5 6

Then the pinout would be:

P2 - DATA (K-Line)
P3 - 12v
P6 - GND

Where on the bike is that connector that you attach the 6-prong connector to?

The connector is under the main seat by the fuses, close to where the toolkit lives.

The OBD connection on the bike is the natural color connector (6-wires). The other connector is black and that is for ABS (4-wires).

If you made your own OBD harness adapter, make sure you don't have everything inverted with the connectors.

Here is a link to a video i made showing how the wires go.And a app to use to read and clear codes.

 Good job!
 Thanks for sharing.  :028:
Tighten it 'til it strips then back it off half a turn.
