MH7201F

[Bartek]

It's a bit dificult - I'll be in garage at evening

I've choose MH7201 with and without external memory

I've received program yesterday, donge at last friday, so I'm newbee

My copmuter works on Win XP Home Edition SP3

I'm sending to You ECU with 8200 form another "proprety" on my garage - I've spoke about this with Hamish

[Bruce Willis]

I send you new program, try it and write result.

[Bartek]

Did You send to ma @?

I've got form Hamish and I'm using MMCFlash 0.8.0 build 11

[Bruce Willis]

Check up connection! Your error says that any answer from ECU has not come.

And thanks for the ECU!

[Bartek]

K-line I think works OK, because Evoscan works proprely

I'll check boot pin - on ECU connector works OK - has 17V while attempt to read

[Bruce Willis]

Yes, such V also should be, all is correct. But you could be mistaken with connection boot pin, at me such block lies, has just checked up, all works perfectly.

[Bartek]

My friend checked out - boot pin inside ECU has 17V too.

[Bruce Willis]

Check up connection boot pin on a picture.

[Bartek]

He checked out boot pin inside ECU - like on picture

[Bartek]

He checked out on other computer with XP Pro, and software that You just sent to me

On similar ECU (MD355869) this problem is appears too.

Immobilizer installed in the car?

[Bartek]

only oryginal immo - with transponder borrowed form "source" car, engine starts and everybody are happy, but source car is now destination to 6A13 engine, so I dont want change or dig in keys.

I know immo codes, so I have to change only 2 bytes in ECU

[Bruce Willis]

Did you tried to remove ECU and read it with out car?

[Bartek]

No.

Do you have ready chart what and where I have to conect (for Carisma '98)?

If no, what I have to connect to program:

- +12V

- +12V Ignition

- GND

- K-line

- boot pin

- + 12V to OP2

- GND to OP2

anything else?

[Bruce Willis]

No thats is enough.

Before try ignition on, than prepare all for reading from one button. And the second variant disconnect immo.

I didn't see as look a socket by this car if to an exchange can disturb immo, as a rule is separate pin on which To a line separate, passing immo.

[samsu]

Check the wire from the 7-pin OBD to ECU.

Share photos ECU internals from both sides.

[Bartek]

I made wires to program ECU outside car, and everything works fine

Thanks for all advices

samsu: K-line and boot pin I've checked from diagnostic connector to inside ECU, Evoscan for logging works fine, so I've no idea what is wrong, but OSP (OutSystem Programming) works good - read and write

[Bruce Willis]

IT is a result.

[Bartek]

Pins in immo box are connected phisicaly

BTW: Do you know how can I deactivate immo at all?

[Bruce Willis]

Yes we can remoove immo in the SW

[Bartek]

You can remove, or you can write (PM or @) how to do this?

[Bruce Willis]

What problem at you to start the car without an immobilizer?

[Bartek]

Error code 54

I have test-ecu and I want to be able to connect it to any car (without removing existing ECU, copy immo code, program my ECU) and fast test why car has problems on idle.... In this model of Carisma are many reasons (3 by-pass valves, EGR, high pressure pump, and ECU) - in specyfic case, after change all parts under hood to parts from 100% OK car, we suspect ECU, and it was good shot. Fortunelly we have almost identical Carisma, for engine swap, so all set key, immo, ECU was easy to connect and check.

[DeeGraf]

So, Programming (writing) Ecu isn't possible without removing it from car?

Regards

[Bruce Willis]

In yours it is necessary open port 2.0, in case of Bartek when ECU it is not read and it is not written, it is necessary to remove immo physically with K line or to remove ECU.
