Problem: Today I failed to read Audi A5 Bosch Edc17cp04 ecu with pcmtuner on bench. Try bench connection pinout from pcmtuner, failed. Using bench module 71. Any idea?
1.Try the wiring diagram from dimsport, reconnect and read again
EDC17CP14 bench pinout
EDC17CP04 bench pinout
In bench select the correct eeprom family for identification.
Some succeed in reading edc17cp14 on bench
1). Edc17cp14 via obd very good with pcm tuner
Connect charger adds extra safety 13.8v+.
