Subaru SSM

Hi guys, new member here and new to Subi's!!!

 

Want to check the fault codes on my 1998 Impreza WRX, realise we can't use the OBDI2 scanner and plug so I tried connecting FreeSSM via my USB to serial adaptor to pins 12 and 13 of the OBDI2 plug. (Tried 12-13 and 13-12). 

Can't get it to connect so thinking my USB to serial may only be 3.3v instead of the 5v that I've read is required.

My questions are:

Do I need to connect the 2 green plugs under the dash before trying to connect the scanner?

If my adaptor is the problem what cable should I buy to get connected?

And lastly......can't see a yellow plug under the dash that has been mentioned in a few posts I've read researching this.

 

Appreciate your advise.

 

Cheers Dave

Have you tried it? 

 

You can always just read the codes from the dash... rather than try and connect a device.

I feel like a '98 may be too old for FreeSSM.

 

re. the cable, I used a VAGCOM cable with an obd2 connector with my '05 Legacy and it worked well.

 

In terms of which connectors need plugging in to put it in diagnostic mode... ugh it seems to vary hugely even with supposedly identical cars... different markets, trim levels... first get confidence in your reading equipment, then you just have to experiment until you get the output you expect.

Thanks, just did the and the code is 24. ICV, check it internally, nice and clean with no drag or anything, moves free and smooth. Checked icv coil resistance, both 9ohm so good. Check supply voltage the icv good as well. Also checked air lines for cracks or splits, nothing there either....

 

What else should I be looking at?

 

Cheers

Are you actually having idle control problems or have just found an error code relating to the ICV? 

 

If you aren't having idle problems then maybe it's an old code... clear it and see if it comes back.

Yea, idle problem. Most of the time it idles ok until the ecl comes on, then it really struggles to idle. Just on the verge of stalling. Stop and restart the engine and it idles sweet again till the ecl comes on and again won't idle. Will clear fault code and see what happens.

 

Thanks

It will probably come right back on... you hadn't actually said what problems you had previously though.

 

A small work around might be to adjust the throttle so that it's open very slightly... there's a small adjustment screw just under where the throttle cable attaches.

It might mean the ICV has a bit less work to do and might improve things a bit.

Thanks Loren, sorry for missing the important bit.... Thought about adjusting the throttle but was thinking the idle would be too high before it goes into error. Need to find the fault... Once we're out of lockdown might get a dude out with the proper scanner to see if there are any other issues.

Cheers for your thoughts.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
