Mundaddy Posted July 22, 2019 Share Posted July 22, 2019 Could anyone give some other suggestions as to what my problem would be. I’m experiencing the exact same issues as this guy with his wrx. I have a 2012 GT limited. I haven’t found any other threads addressing this problem. I also have replaced the same clutch switch thinking it would resolve my problem but it did not. https://forums.nasioc.com/forums/showthread.php?t=2845069 Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
DrD123 Posted July 22, 2019 Share Posted July 22, 2019 there are two clutch switches - there's the clutch switch (2 pole connector) and the clutch stroke switch (5 pole connector) - the latter is used in the starting circuit, etc. - both switches connect to the ECM, so maybe it needs both?

Mundaddy Posted July 22, 2019 Author Share Posted July 22, 2019 Not sure about the clutch stroke switch. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
coco26 Posted July 22, 2019 Share Posted July 22, 2019 I had similar symptoms when I bypassed the two pin switch by jumpering it. You replaced the switch, so maybe check the wiring on the car side to make sure there isn't an issue there? Link to comment Share on other sites More sharing options...
Mundaddy Posted July 24, 2019 Author Share Posted July 24, 2019 You mean something like a loose grounding wire? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
coco26 Posted July 25, 2019 Share Posted July 25, 2019 (edited) One of the pins on the connector should have some voltage going to it that the switch either sends back to the ecu or pulls to ground. Make sure you have that, then give everything a shake to make sure you don't have any loose connections. Edit: In the picture, it looks like the power to the switch also goes to pin 8 on the OBD2 connector. That could be an easy place to check the voltage. Could be that fuse is blown. The Stroke switch goes directly from the starter relay to the ECU, so if your car still starts, that likely isn't the culprit.

DrD123 Posted July 26, 2019 Share Posted July 26, 2019 If you have all of the symptoms (not just the gear indicator) the clutch stroke switch is a 5 pole connector - one pin goes to the starter relay, two go to the VDC control module. So I wouldn't rule out that it's part of the equation. The 15 WRX is a little different - it has two clutch switches (a clutch switch and a clutch start switch - both are two pin connectors - one does the starter relay function that the clutch stroke switch has the LGT and the other goes to the ECM like the two pin one in the LGT - neither go to the VDC module directly in the 15 WRX.

Mundaddy Posted July 27, 2019 Author Share Posted July 27, 2019 I do not have the best knowledge into wiring as I’m just learning and like trying things on my own. Here is the last picture I took of the two switches and what’s going on down there. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
SchwarzeEwigkt Posted July 30, 2019 Share Posted July 30, 2019 Which switch did you replace? If we’re talking about the upper one (behind the black wire there). Its job is to tell the car that the clutch pedal has been released all the way, as in your foot is off of it and it’s totally out. The cruise will disengage if you press the clutch down enough for that switch to change state since the car can only control speed by manipulating the throttle and only when you haven’t disconnected the engine from the wheels. There is almost definitely another switch on the back that for most cars only functions as a starter inhibitor switch. Clutch isn’t on the floor, the switch won’t close, so the starter won’t turn. I’ve never had to replace one of these on a Subaru, but I have done it on a couple Audis. When either switch would go, cruise would not work and revs would hang between shifts. It’d store a code for “clutch switch signal implausible” or something like that since both switches can’t be pressed at once. If the lower one went, the car wouldn’t start, though you sometimes could get around it by stomping on the clutch a few times to get the balky switch to cooperate. Whichever switch you didn’t replace you ought to take out and test with a multimeter. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Mundaddy Posted August 18, 2019 Author Share Posted August 18, 2019 I’ve noticed while driving that sometimes engaging the brake can make this problem start happening. Might have to take a look there as well. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
