Bench Setup
Posted: Mon Jun 18, 2018 4:15 pm
OK, I have either gone mad, lost the plot or just am way over tired.
On Saturday I decided to start back into the dash, ecu hacking etc, it has been many years and I have probably forgotten more than I can remember. However, I started with a VY dash and ALDL cable. connected the units up and went to have a play but go no comes what so ever. No response from the cluster no information on my sniffing tools.
So went hang this and tried a VT cluster instead. Same result. Got worried I completely read the instructions wrong and so ran over the road to a mates place and plugged into his VY crewman and got responses on the tools.
SO couple of questions or need for a sound wall and other brains than mine right now....
I connected the cluster to 12V and ground. I also connected my ALDL connector to 12V and both the GND and Signal GND to gnd. I then connected the UART line from the dash (green with yellow from memory) to pin 9 ALDL connector (was red on my plug). I suspect that it needs a clock of some description or the BCM to be able to communicate properly. I refuse to believe that Arrow when they had this stuff on the bench would have had a BCM but stranger things have occurred.
any suggestions? i truly am at a loss right at this point. I am trying my VY dash only so that I can get my eye in again and thus then start looking at a VF dash I have on my bench. Although suspect it will be GM LAN and thus will need other things as well.
Is there any way to trick a tech2win device that there is a tech2 on the end without a J2535 pass through? I really don't need yet another cable to loose.
cheers
