Title: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 20, 2018, 04:32:09 AM I am trying to read this ecu on the bench, but the bench harness I have isnt powering up the ECU when I have 12volts hocked up
Ecu is a med7.5 out of a 2001 Volkswagen Jetta 2.0L non turbo Title: Re: 2001 vw Jetta me7.5 pin out Post by: vwaudiguy on October 20, 2018, 08:21:32 AM Maybe it's hocked up wrong? Check voltage @ the connector?
Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 20, 2018, 01:14:17 PM You mean at the ecu side or odb?
Title: Re: 2001 vw Jetta me7.5 pin out Post by: vwaudiguy on October 20, 2018, 01:58:13 PM Common sense would say to check for voltage at the last point before whatever you're using connects to the ecu.

Title: Re: 2001 vw Jetta me7.5 pin out Post by: Kompiesto on October 22, 2018, 06:12:09 AM You cant read ecu without immo off. If you open ecu and do "immo off" you can read and write via obd on the table. Only way without modifing eeprom is read bin in bootmode. Ecu on table should taking ~0.2A of current. Check connections... you should have chance to connect with ecu by VCDS. You must connect ignition signal to +12.
Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 22, 2018, 07:29:02 AM i have power to all 3 power pins and ground to the ground pin, ecu will no connect with vcds or odis is there something i am missing
i added picture of what i used to wire it up, i tried mpps v13 and cmd flash to connected with no luck ecu side 12 volts at pin 3,21,62 ground at pin 1,2 and k-line is pin 43 obd side i have ground pin 4 k-line pin 7 pin 16 12 volts Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 22, 2018, 07:34:11 AM Found the issus my k-line wire came unhocked under the tape
Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 22, 2018, 07:37:12 AM And mpps is reading on the bench with out issus now
Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 23, 2018, 06:36:34 AM Is this ecu eeprom desoilder only to immo off?
Title: Re: 2001 vw Jetta me7.5 pin out Post by: Kompiesto on October 24, 2018, 11:02:56 PM In ecu is eeprom memory. You must reprogram it by external programmer to immo off.
Another solution is reading it in bootmode without desoldering memory... http://nefariousmotorsports.com/forum/index.php/topic,1168.0title,.html Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 25, 2018, 07:44:00 AM Would mpps read when it's in boot mode? I'll also check that link out. Thank you
Title: Re: 2001 vw Jetta me7.5 pin out Post by: bororobbo on October 28, 2018, 04:04:12 AM Use galetto 1260 for bootmode and a modified ftdi cable (edited serial number) ground bootpin with resistor for 8-10 seconds then read/write
Title: Re: 2001 vw Jetta me7.5 pin out Post by: birchbark506 on October 28, 2018, 04:29:10 AM I dont have a ftdi cable I'll have to order a cheap one, I only have mpps v13 and cmdflash-obd and the real ross tech cable and the real vas 6164 odis end
