How to make a Kess V2 Subaru cable to OBD write ECU

Read many posts to have the pin diagrams for the Kess v2 ecu tuning master Subaru cable. And luckily, i found this:

18-0

The man has a genuine kess subaru cable., and measured the cable for someone in need.

But it seems there is something wrong.

He has the red obd connector the wrong way round

A mate in the forum also says
”what you have as pin 1 is actually pin 9 and what you have as pin 15 or should be 16 is actually pin 1
when you hold it the other way round you will see pins 4 and 5 are sticking out more than the others, these 2 pins are gnd”

Probably right. The man made up the pin numbers on the OBD connector as reference to the way he did hold the connectors in the picture.
He must have missed pin16 but that pin has no connection to the DB25 so it should not matter.

Followed the instruction, i made one and tested ok.

Connect to the battery charger

Connect jumpers under the steering wheel

The car now is in service mode

Start Auto ECU Programmer Kess V2 v5.017, and select Car




All done

I used it to write ECU successfully.

Ps. Something good i found when i searched info.

Maybe it would helps someone.

According to the OBD generic standard, pins 4 and 5 are designated grounds. But in the 2000-2004 wiring diagrams, pins 12 and 13 are shown as connected to ground. (According to OBDII, pins 12 and 13 are data connections.)

Here’s what the OBDII pin out is supposed to be:

Note that pins 1 to 8 are at the wider side of the connector, and 9 – 16 on the narrower side.

Here’s what Subaru shows in the 2007 (also 2005-9) wiring diagrams:


As we can see, the pin locations are the same as the OBDII standard.

And finally, here’s the way it’s shown in the pre-2005 Subaru wiring diagrams:

Note that the locations of pins 1 to 8 are on the narrower side of the connector, even though the OBDII layout has remained unchanged.

This isn’t just a question of which way the connector is viewed. Pins 1 to 8 are always on the wider side of the connector, whereas the pre-2005 diagrams have them on the narrower side.

This anomaly affects where the connections are made. As noted, in the 2005+ wiring diagrams, pin 16 is shown to be connected to the always-on 12 V. But in the pre-2005 diagrams, pin #1 goes to an always-on source, SBF-5, in the engine compartment fuse box. (There isn’t a separate fuse for the OBD connector 12 V supply.)

In addition, as noted, the apparent inversion of pin locations affects the grounds and data line identification.

So a “heads up” if you’re using 2000-2004 wiring diagrams and working with the connections to the OBD2 scan tool.

Notes on using KTAG K-TAG ECU Programming Tool

KTAG Programming tool has released to the version V2.11. It specializes in BDM function. What should be noticed when using the K-tag programmer? Following are helpful notes for owners.

NOTE1

Apart from some common protocols, K-TAG ECU programmer also supports BDM MOTOROLA MPC5xx protocol.

NOTE2

K-TAG and KESS V2 share the same software but they are two different products. KESS V2 is able to do OBD function while K-TAG cannot.

NOTE3

If you find out that K-tag can only read from the slave files but not write. Make sure refer to the ECU programming list instruction. Some ECU can be read but not write, like EDC16 Audi.  Others can only be written but not read vice versa.

NOTE4

Tokens are needed when K-TAG does ECU programming function. V2.11 KTAG on OBD2TOOL has Unlimited Tokens, it has a Renew Button, when you run out of tokens, only need press the renew button, then you will have tokens again.

19-1

NOTE5

K-TAG comes with AC adapter in the package. You do not need to buy them separately.

NOTE6

You should Disconnect Internet While Using  ktag v2.23, Otherwise It will get damaged. And do not update K-TAG programmer, if you really want to, you should ship back the Multiplexer, and Pay $240, then the factory will replace a brand new one for you.

NOTE7

Power not connected absolutely or incorrect installation may lead to the error: “Communication error: please check power and connections” (as the picture below)

FAQs about KESS V2 V2.15 OBD2 Tuning Kit

KESS V2 V2.15 is a very popular Auto ECU Programmer and is probably the most advanced tool available today. My customers feedback some problems. Here are the FAQs about below:

Frequently Asked Questions when using KESS V2

Q: I am wondering now what is the solution to unlock your ECU?
What to do to avoid your ECU become locked?

A: EDC15/16 can unlock by using KESS V2 V2.15 OBD2 Tuning Kit without Token Limitation.
When your KESS  V2 Token use up,pls follow below article to add Token.
Kess v2 fw v4.036 Add Tokens Manual

Q: I will start program EDC16, fiat/alfa/lancia, which hardware is probably better, KESS V2 or Galletto?

A: KESS v2 is better one with no token limitation and no checksum error.

Q: Which computer system can KEES V2 be installed on?

A: KESS V2 can install it on Windows 7 and Windows XP.

Q: How to update KESS V2 from Software V2.15 Hardware V3.099 to Software V2.22
Hardware V4.036?

A: Well, SE87-B can be updated to SE87-C, but need to send back the main device and pay 95USD. Please don’t update it yourself, or it will damage the firmware of KESS v2.

Q: What is the difference between KESS V2 and K-TAG ECU Programming?

A: Beside world-wide famous brand cars, K-TAG also supports trucks, traktors, bikes and work with a small part of motorcycle. Otherwise, KESS V2 has OBD function (means KESS V2 program ECU by OBD diagnostic cable) while K-TAG doesn’t have.

A:Difference between FGTECH Galletto 4 V54, Kess V2 and Ktag

Q: What is the difference Between KESS V2 Tuning kit and Fgtech V53?

A: They both can do many cars, but they do cars via different ways. Fgtech V53 has BDM function, but KESS V2 does not have. KESS V2 has Anti-mediation lock module, it can do new and encrypted cars better than Fgtech V53.

Q: Someone told me that KESS V2 can’t do EDC17 well, such as Bosch EDC 17 (cp04-CP14-CAN-Med17.X) and Bosch Bosch EDC 17 C54 (Passat, Golf, Crafter, Octávia, Yeti-VW).

A: Yes, KESS V2 can’t do EDC17 at present. It can do EDC16 well, but when you do it, you need to connect the Anti-mediation lock module to read and write data for vehicles. Becuase new style vehicles have new encrypted ways.

Q: How many kinds of languages does KESS V2 support?

A: Supported language including English, German, Spanish, Italian, Portuguese, French.

Q: When KESS V2 read ECU, I got checksum error.

A: After reading the software, KESS v2 will automatically calibrate checksums. KESS V2 doesn’t work with truck, because the truck voltage is too high and KESS V2 will be burnt out.

Q:UART pinout / connections on RX KESS v2 and TX KESS v2 with USB adapters …It seems to have differences between the connections…

A:Click to know RX and TX KESS V2 UART Wiring Connection Solution
