mjm4jc Posted May 31 Author Share Posted May 31 IF someone can help with this question I can probably speed up the troubleshooting process. In the 1995 Subaru Impreza FSM (Auto trans and differential diagnostics section, page 39-40) it shows 2 connectors that need to be probed to troubleshoot the Duty C. One is the T4 and the other is the B9. I have an idea where the T4 is, but not exactly sure. I did find one connector in the back and on top of the transmission that seems like it could be the T4. The problem is that is only has 13 pins in the 16 channel connector. Not sure if that is normal, whereby the picture shows 16 pins, but in reality there's less? Secondly, the diagram shows that the B9 and T4 connector join together at some point. Looking at the diagram, does that mean that other end of the T4 connector, (where it plugs in),-- is the B9? Of should I be looking for another totally separate connector? Thanks! Link to comment Share on other sites More sharing options...

lmdew Posted June 4 Share Posted June 4 I'll be back in Colorado in the next couple of weeks and can ship the TCU/s if you want one or more. Link to comment Share on other sites More sharing options...
mjm4jc Posted June 4 Author Share Posted June 4 Ok thanks. Just so I don't waste any of your time, what numbers on the TCU's have to match? Is it just the first five.........31711? Or does the entire top row of letters and numbers have to match? As I'm sure you know, there are no other years or models of Subarus that have a compatible TCM with year 1995 Impreza.

mjm4jc Posted 2 hours ago Author Share Posted 2 hours ago Hello everyone, I'm back at it again with troubleshooting the TB and the fault code 24 (Duty C). The only progress I made since last posting was that I swapped TCU's. This led to no change at all. I think I'm going to swap out the Duty C solenoid again, even though this one is pretty new. When I did the ohm test at the T4 connector, it was out of range (between pins 4 and 11). I'm assuming that means the Duty C is bad? But there's is a strange thing I notice that I would like some clarification on. So when I probe the FWD fuse socket at passenger firewall (key off and no fuse installed) I get ground on both sides of socket. When I put the key on (no fuse installed) I get ground on one side and 7.9v on the other. When I install a fuse in the socket (key on), I get ground on both sides. Does this seem strange? If so, I was wondering if someone here on the forum can probe their FWD socket for me and see what readings you get? Reason is that it may help me further troubleshoot the Duty C. Another question I had has to do with sending power directly to the Duct C to by-pass the harness in case that's the problem. The schematic shows that the brown wire in the T4 connector is for Duty C. But when I probe that wire, it's ground. I thought that wire should have voltage, since the Duty C gets its ground inside the tail shaft housing. What am I missing here? Thanks guys!
