EDC16c34 1.4 hdi

[Stanton]

Ive done lots, only the first I done by OBD, then learned far better/quicker/safer to do with BDM tool!!

I done a fiesta tdci 1.6 just last week, same ecu, no problems. This is the first one and its VERY strange problem...

Probably something went wrong during the step when ecu aluminium cover was taken off ( hardware damage ).

There is no problem doing this ecu's over the OBD - just make sure you switch ignition off more than 5minutes after flashing ( power latch ). My Byteshooter prompts the user to do this, it also has a clock to measure this 5min period. This way you won't loose injector coding or ecu coding itself.

Offtopic:
So it seems that 5% on injection map and 3% on rail map does not destroy ecu+injectors, it is enough only to read the ecu. Lo loo1981, check email

@Stanton:

Usually there is a power supply stage for injectors. Sometimes this power supply stage fails ( although I have seen this only on SID801 once and on a Bosch EDC15C2 ). Tell me one thing: did you use only the BDM pads to connect to the ecu or you supplied the ecu onto its pins with power and ground? (as if it was a Siemens ecu, for example ). I am just trying to make a connection here, this is why I need to know.

I encountered a strange situation with a EDC16C34 from a Partner 1.6HDI. I read with BDM, tuned the flash, but flashing process failed at 40%. Every attempt after this failed. Luckily for me, I had full BDM content and a spare ecu, so I put the content into spare ECU and I let the client go.

After this I had several days for testing. First I heated up the PCB with hot air gun - no results. After this I put ecu in a refrigerator for 24hours - no results.

After this I connected again to ecu on BDM pads, but put on these pads and the area nearby a large ammount of liquid flux and started heating up the PCB in that area. After 5-6 attempts, PCB started to smoke in one area, I insisted with hot air there and as I had a car for testing, I cloned the original ecu by writing its content into this broken one. Finally, after insisting on that BDM pads area, I managed to flash succesfully the ecu, put it back on the car and engine started.

It seems the ecu had a very weak point from the factory related to one of the connections to the BDM pads. By putting flux and heating, I restored this connection and ecu was back to life as I managed to program it.

Of course Stanton's situation is different. I would advise him to try replace the 3 power supply drivers located on right side of ecu (BDM port on low side).

Thanks for the reply alexs:

Only bdm pads were used, with adaptor...not soldered.

I noticed when I was pry-ing the cover off that the PCB was still bonded to the cover (not the main case)...so I was pulling cover AND PCB away from the main case.. by maybe 5-10mm.... so this could have strained some tracks as I was effectively bending the board.

But I dont get why the compatability chksum was wrong? wtf is that about?!

Thanks again for the help...

It depends of the side you start to remove the cover off...usually you have to start the opposite side of the area that is covered with silicone so you might not hurt the PCB by trying to lift the cover while it is still attached to the PCB by that silicone. And always try to heat the cover very well with a hot-air gun, it makes things a lot easier.

Not specifically EDC16, but a succesfull way to lift off the cover. Correct side to start with removal! If they had warmed up the case with hot air, it would have been easier. It is not the right method in this video, it could have been more accurate, but guys succedeed.

1.4HDI - from my experience edc16C and C3 with early models were giving much troubles, the new ones (superseaded part numbers) are hardwarewise edc16c34 (that is written on the box) but after you connect with lexia or pp2000 it is giving reference as oryginal edc16c. Common fault is the driver with can communication (the one located closest to bdm pads), the other (as someone mentioned) is high voltage stage (didnt managed to fix it yet) and most expensive one is multilayer pcb.

Hi everybody, someone can con firm me that i removed correctly egr function from this map?
206 1.4 hdi qith edc 16c34, I found only 2 egr maps.
thanks
