I'm not sure what you mean by reading parts. Can you give more detail?
Can you give the step-by-step procedure you are using? It SHOULD be, hold pin to ground with power off, power up ecu, after about 3 seconds release ground. You should then be in boot mode.
I followed the instructions for Gal 1260:
Ground ECU pin:
I used the soldered the spot underneath the chip instead of the chip pin itself as it's indicating that's it's part of that in the above picture.
Launch Gal 1260 in boot mode, ground the pin for 3 seconds upon power up, released the ground but nothing came of it.
On the bench?
If so, of course you can't connect to other modules that aren't attached.
Yes on the bench bud, I though it may have been due to it being on the bench and not reading the rest of the modules
