Re: Which computer does Tech II talk to for SRS/ABS/ACC? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Which computer does Tech II talk to for SRS/ABS/ACC?, techlectic, Sat, 6 Jun 2009 13:23:50 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Does the Tech 2 power up at least when connected to green plug?
If not I would first check for proper power and ground to connector.
I think the black socket feeds power and ground to green socket, pin 9 and 10 on both.
I assume the green test plug has a straight wire to each module but sharing one common. SRS is 1-8, ACC is 1-3, EDU is 1-2 and ABS is 1-4 so I have a hunch that something has happened to the pin 1 wire somewhere along the way since if the Tech 2 powers up but cannot read any of the modules, that's the only common denominator.
So you need to get a wiring diagram and see where that wire is spliced into all modules and measure for continuity from there to green socket.
