Problem during writing MPC555 with BDM100

[P2XA]

Hi everyone! A problem occurred during the recording stage MPC555 92-94% (error writing data block) ecu isedc16c3 (47), the car is Peugeot 307 1.4hdi. This programmer were successfully retrieved all the firmware from the two ECU (SW version 1255) Wiring to the BDM ECU following::mad:

After this error by click button +12v on program show message "communication error"

[bazare]

either your bdm is dead or your ecu is dead.

[grinovsky]

yes,try to use XPROGM to read write MPC555
and repport for result

After this error by click button +12v on program show message "communication error"

What BDM100 you have ?
How you supply ECU - important to say as -> from BDM100 ?
If yes and it is china tool ralay inside is small shit relay max 250mA current can go via it.
Check did you have +12V on pin's 2 and 9 on BDM100 connector .. ?

After your measurement and answare we will help.

My BDM100 is a chinese clone.

I just tried to read the ECU which had blocked the use of Xprog-m and lo and behold my BDM100 successfully read all the information from the ECU. I completely forgot that I have not engaged pins 2 and 7 in accordance with the picture ...

It is nice to read that.
Good job good all...

Thanx to all! Very good Job BOYS...

How long cable you have from BDM to ECU ?
From what you provide Supply DC to BDM and ECU ?

Give more info ...

Included with the programmer was the power supply 12v-2A. I turn on the AC / DC adapter into the programmer and connect the findings of BDM with the ECU as shown above, then run the program and hit the +12 v on. After this message appears communication inteface error; mpc family error:

[elchip]

Where is that picture ? You edited post no attachment ?
Did you have +12V on a moment when you hit ON ?
If you supply ECU on ECU connector with BDM100 relay in BDM100 is 90% dead contact. The output on china BDM100 can supply only ignition on BDM socket not full ECU....

I want to push you in right direction but I need more info.

[P2XA]

I am applying +12 V only through programmer BDM pinout

[P2XA]

Does anyone know which pins on the need to submit additional +12 v of the ECU? and whether you want to do this?

[elchip]

You can measure +12V on pin 2 and pin 9 BDM ?

[P2XA]

I measure up the voltage on 2 and 9 contacts at BDM connect the programmer to the ECU, and saw no +12 V and about 1.25v.

[elchip]

To get +12V you need hit ON button to command output +12V. And need fast voltmeter or oscilloscope to can hold measured voltage ( it is short ) and if no respond from MCU BDM100 automatic off output. I have one suggestion for you but I need to know do you usage FRAME with adapter bosch or usage solder wires ? If you usage soldering metod simple manual put +12V on pin's 2 and 9 on BDM pins on ECU.

DO THAT ONLY IF YOU 100% SHURE WHERE IS pin 2 and pin 9. In other way you can damage ECU if you put +12V on wrong pin's !

Disconet wire's from BDM100 on pins 2 and 9 if you manual put +12V on ECU BDM pad's.

Your error is understandable! See picture.....

[Novik_UA]

You can also try to put 12V direct to ECU connector pins, and measure it, maybe your power supply did't provide 12V.
Don't forget to connect ground(-12V) of BDM to ground of power supply if you try it.

[rappttor]

leave the bdm without ac adapter and just give to the ecu vcc on its socket, that should do the trick...
if this still give family error try to give vcc on both sides bdm and ecu socket...

I had problems with BMW E60 yesterday ecu DDE7 .After several attempts reading and failing i disconnected the power supply from the BDM adapter and connected power supply to the ecu connector directly using PC power supply and that did the trick. Readed 10 times without error

Yes you have full right about that.
All who do that only must be careful about good pinout.
Wrong pin orientation and +12V on wrong place is END of ECU.

All the best to all.

[P2XA]

Now solder to the ECU via BDM pinout, and when you +12 v on an error (with clicks disappeared inside BDM):
+12vcc error or communication error

[jovime]

Ecu is dead. Search one on a scrapyard and clone the information you read from the old one. At least you have a backup :)

This picture and picture of post number 20 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[P2XA]

Problem solved. The ECU succesfully cloned and work fine.
Thanx to all for help!
best regards

Nice to hear that ^^

Hi guys,
coming back to the BDM100 error, would the extarnal +12V (for EDC16C9 and C39 connected as in the the picture) help to avoid this "communication error" ?
I mean if the clone BDM100 is failing so easy to supply the needed +12V, why not use an externel +12V all the time? Does it make sence?
