Testbench setup?

[siLc]

Invested some 4-5hrs and made my own little testbench out of leftover factory wiring and connectors. Powered it by an old 500W ATX computer power supply. Its for setting up 3Q098065x Lane Assist cameras, MQB-style PDC modules and instrument clusters with the 32pin blue connector on the VW PQ platform. It has provisions to add stuff on Infotainment and Comfort CAN busses.

I wired it so when powered up, terminal 15 is always on. This shouldn't pose a problem with any said modules which take a direct terminal 15 input to work correctly? I only have a gateway at the moment to test with and it talked fine.

Picture link doesn't work for me.

Most of our test-bench setups do not have a separately switchable Terminal 15 either; power them on, and both 30 and 15 are on. It usually only matters when modules do "house keeping" after terminal 15 turns off. For example, some older ECUs would only store changes to adaptation channels when that happened, and they obviously couldn't do that if Terminal 30 shut down at the same time.

I corrected the link - (hopefully) it works now.

Nice to know. For my purpuses, I don't think I'll be hooking up any ECU-s.

^^^ hmm......... picture is not available to me either - not sure if it's because stuff happens differently in the southern hemisphere (like water draining in a sink), but that's quite a long URL string in your post!!!

That's just Google Photos giving me a hard time once again...



Most PQ modules have power/GND wire gauge specified as 0,5mm2 but some have larger 1,5 to 2,5mm2. An example is the Passat B6/B7/CC CCM module. With nothing attached, would this really need 2,5mm2 gauge wiring?

Google photos does not seem to be forum-friendly at all.

I don't think so. The reason it has such large wiring in the car is that it powers lots of other stuff; lights and so on. If you just want to talk to it on the bench, you only need to power the module itself, not all the down-stream stuff that the module powers.

1K0 gateway???

1K0 gateway???

RoW Passat B7 gateway 7N0907530Q as you can see on the screen.

2) CAN-High/Low for Powertrain, Infotainment, Comfort, Extended, Running Gear makes up for 10 pins - that leaves CAN-Diagnostics and CAN-Instruments which brings us up to 16 pins already.

Actually it's 7 pairs of wires (not 8) Please, explain what did I miss. Building similar box with DB25 right now.
