RE: Diagnostics in India

The datasheet for the processor should have details on how to read and write the programme memory. I have only played with one NEC processor, a much earlier version in a mazda ECU. For that I had to make up an adapter and read it using an EPROM burner, hopefully these later chips should be easier.

 How do you propose we do that?

IDAPro can disassemble the code from the NEC processor if we can work out how to read the code from it.

Not sure, I got a picture of only the NEC chip. Its marked as "NEC Japan D70F3180GJ-40 V850E/GP2 0534KX018. 

Let me know if you want any pictures in specific. Will have to pull out the ECU again.

Is there *anything* we can do on these ECUs? Sigh!

Rhinoman - Any analysis based on the pics I have posted?

Sorry for the delay in the PCB pics. Finally managed to get hold of them. Here is how the Euro - III Baleno ECU looks like on the inside.

If you need any specific pics in general, do let me know.

PS - Looks like you can't zoom on the pics, so if anyone needs the higher resolution pics, PM me your e-mail address and I shall send you the original file :)

The image i have posted is a mirror image....

 

pin 7 has 9v(this varies)

pin 9 has 3v(this is constant)

pin 16 has 12v

If you have access to a voltmeter then check what voltages you have on pins 7 and 9, use pin 4 or 5 as the meter ground.

Sorry in the delay of the PCB pics. One of the screws on the ECU casing seems to have slipped and finding it tough to get it out. Will get the pics in the next couple of days.

I am counting the connectors, I am aware that the GV ECU is a Hitachi but the OBD1 Densos on the Balenos all seem to be 3 connectors. The OBD1 Balenos that I've seen also don't have pin 7 populate don the J1972 connector. Once we see the PCB we will be able to see which components are fitted.

What tends to confuse is that a Euro 3 Suzuki ECU in Europe would have been OBD1 and a Euro 4 would have been OBD2 but in India the Bharat regulatoins specify only Euro emissions not Euro diagnostics so you can get an OBD1 Euro 4 ECU.

Just on the offchance you're counting the connectors - the ECU in my GV is a four connector OBD1 ECU.

The "C" connector is used for automatic transmission control - or would have been if I had an automatic.

Spadival was one of the first people to get an interface working using the SDL protocol. That as on a G16B Indian Baleno but he moved to Australia (I think) before we had a chance to do any real work on decoding the data. I will look back on his old posts on RedlineGTI to see if there is any good information there.


 If it turns out to be OBD2, is there any other tool I can use to data log?

I know spadival from TBHP and over the last few years have totally lost in touch with him. I have also posted the same info RedlineGTi as well.

I still have a couple of friends who are running the OBD1 ECU on their cars. If you want I could hook you up with them so that you can do some extensive research.

Will try to post pics of the PCB by the end of tomorrow. This version comes with a heated O2 sensor and an EGR Valve too.

Thanks a ton in advance.

Cheers,
Rahul.

Thanks a ton @fordem.

Managed to take out the Euro-III ECU as well today.

ECU in stock location.

IMG_6225-1.JPG

Couple of shots of the couplers..

IMG_6227-1.JPG

Another one.

IMG_6228-1.JPG

 

ECU part number..

IMG_6229-1.JPG

 

ECU Pins.

IMG_6233-1.JPG

 

Will put up the pics of the PCB in a couple of hours. Unable to find the tiny star screwdriver to open it up.

@rhinoman - Let me know if you want anything in specific. Also if I purchase the ALDL cable, would I be able to do data logging?

OBD.JPG

Pin outs are as follows:

4 - Black = chassis ground.
5 - Red & Black = signal ground.
7 - Pink (I guess) & Green = ISO9141-2 K line.
9 - Yellow & Green = SDL (Suzuki Diagnostic Link).
16 - White = 12V power.

I'd say OBDII compliant

I own a Baleno with the Euro III ECU.

Here is a pic of the OBD plug.

OBD.JPG

Pin outs are as follows:

1. 4 - Black.
2. 5 - Red & Black.
3. 7 - Pink (I guess) & Green.
4. 9 - Yellow & Green.
5. 16 - White.

Now can someone help me decode this? Is this OBD II compliant?

Wanted to pull out the ECU as well and get some shots of the PCB, connectors, ECU Code etc but then mom started threatening that she won't serve me lunch if I didn't come upstairs immediately. Will go and try to pull out the ECU a little later in the evening.

Let me know what you would like to know and I will try to the best of my abilities to provide you with the info you need.

I am aware from emails and from reading posts on Teambhp that there are a lot of problems with Suzuki/Marutis vehicles. Currently India mandates Euro emissions levels, OBD1 is mandated from October 2010 and OBD2 from 2013. I have set up this sub-forum in the hope of collating information regarding which vehicles are currently using which standards.
We know that some ECUs use the SDL protocol on pin-9 of the OBD2 connector. Some ECUs use a Key Word Protocol known as KW81, these ECUs will connect to an ELMScan tool as KWP2000 fast init but won't return any data.
