RE: EDC15VM 4B2 907 401 Write problem
The flasher thru obd injects bootloader in c167 ram in order to pull pin pol.4 low (pin24 on flash) in order to execute erase and write comands....if the hardware is faulty it doesnt pull the pin 24 low and doesnt erase flash no matter you have diagnostics or no
Try grounding the 24th pin of the flash to gnd before executing comands.....if that doesnt work probably a faulty flash then,,,,,,i usualy desolder those and do them with my beeprog. 10 min job I have even encountered faulty flash memories which cant be erased even with a programer Post a picture of your ecu hardware |
