3 Ways to Read and Write EDC15C2 with KT200

 How to read these PSA Peugeot Citroen old dinosaur EDC15C2 ECUs with KT200/Foxflash?  By OBD, bench or boot?

 

1.OBD: OK

OBD reads ok.

obd for flash not eeprom. obd cannot clone.

If car is not there, not possible to do OBD.

 

 

2.Bench: OK

Old PSA edc15c2 bench ok with kt200 or foxflash. Manual checksum with winols.

Full system work very fine. Have make many edc15c2 full backup.

Lot of wire for this very old ecu. extra wiring with 3x120ohm.

To identify ecu edc15c2 peugeot you need to click id several times. the first time he doesn’t identify but the second yes.
Reading and writing egr off cheksum manually.

 

Do several times edc15c2 3plug and 1plug, Impeccable.

 

edc15c2 1plug pinout

For FULL MODE modality use also:
– Rainbow flat cable
– 3 resistores 120 Ohm

Note:
Connect also the rainbow flat cable as shown in the figure only to communicate with the FULL MODE driver.
To read and write the Flash and the EEPROM using the FULL MODE driver, in addition to the multifunction cable, also connect the violet, orange and brown wires of the rainbow flat via a 120 Ohm protection resistor. In this way the ECU will enter Full Mode mode.

3. Boot OK

How to read PSA EDC15C2 in boot mode?

Connect multifunction cable as follows.

Pinout EDC15C2 to KT200/Foxflash

To read and write use the OBD serial driver.

Attention:

If the ECU doesn’t enter boot mode, proceed as follows:
→ Switch off the ECU and remove the grey wire.
→ Connect directly to ground the boot pin with a needle.
→ Switch on the ECU.
→ Remove the ground.
→ Launch the driver and click the read / write buttons.

Question:

When I read Edc15C2 PSA ecu id, why are there dots in the place of the data? It read and wrote flash and eeprom.

Old ecu so cannot decode data but still works.  He identifies with dots but reads and writes good.
