Hi all,
I was about to buy an Innova 5610 Bi directional scanner but it looks like it does not support Bi directional active tests. Can anyone recommend a decent scanner that will do Bi directional on a 2008? I'm not looking to break the bank on a new scanner but would like something that can at least command my evap solenoids.

Thanks
Mike

 

Harbor Freight had one for around $1,000. Now that GM doesn't use Tech2 anymore there have been good prices on ebay.
A jumper wire can trigger them; under hood is PWM.
Why? What are you looking for? I bet some internet guru is sending you on wild chase.

 

Thanks for the info .I just ordered a launch x431.
Just chasing down a problem (P0455) Thought i had it fixed when I found a rusted out line.

 

Have you already replaced the vent valve and cap?

 

Yes the old vent valve had some cracks on the body so i replaced it. did the cap 8 months ago...I could not find any other leaks when i did a smoke test.

 

Many times the rubber gasket on the valve are at fault, the get damaged especially if you had to reuse the old one. Some come with a new gasket, some don't.

You can manipulate the vent solenoid with a jumper. If I recall correctly the vent is N.O. and the purge is N.C., My mind is not working real good today I may have those backwards.

 

I'm going to have another look and run the smoke machine again...I'll post the fix as soon as I figure it out..Thanks for the input
