well I just put a new battery in and I thought I solved my vsc/track and abs light issues. But now when I start my car it runs perfectly drives great but every time I get about 10 minutes/miles into my driving all the lights come on the car still runs perfectly when there on? I'll shut the car off and when I turn it on again no lights again for the same amount of time. Weird? Also don't have any check engine light so my OBD2 scanner doesn't show anything. Thanks in advance for any help I love my ISF and this forum 👍

 

No but it does sound like a battery issue, I kow others on here have reported strange things like this that were battery related.

 

I agree 100%. But I just installed a new battery 2 days ago

 

Personally I would put in another one before trying anything else, I had a battery that was brand new blow up and spray acid all over my engine bay.

 

I occasionally experience that too. I think it may be the gas cap. When it happens, after I shut the car off I re-tighten the gas cap and then I wont experience it again until next time I put gas in the car. I can't be sure until I just replace the cap altogether and it completely stops happening.

 

50% of my battery purchases end up in bad cell returns within a week. Def try another.

 

Hey,

Also worth checking your battery wires for damage.

Bad connections can cause symptoms like the ones you're describing as well.

Hope you can get it sorted soon mate.

Cheers.

I will try that. The battery is showing it's holdina charge and looks fine I don't know if they will let me trade it in if there is no sign of malfunction?
I'll try that any thing I'll try once at least haha. It isn't throwing a check engine light though. Wouldn't a gas cap do that?

 

Are you connecting with Techstream or a generic OBDII scanner?

 

I will be doing tech stream tomorrow I'll keep the thread updated

 

i had this happen to me on a different car not F and it turned out to be the alternator , might get that check out also.

 

well I hooked up the tech stream and got a few codes but then it clicked off saying ecm not responding which really worries me. I have had many cars but this problem has stumped me! Still no check engine light but every other light was on.

 

I used techstream I'm wondering if I need to clean my ecm or if I need to find a new 1 because the car wouldn't communicate with it. I know it works well cause I immediately hooked it up to my rx330 after and it worked

 

When you turn the F on, does your check engine light comeon and then go off when the engine actually starts?

Does the techstream connect to the car at all?

From the codes you posted, it looks like you need to recalibrate the yaw sensor.

If you originally used a cheapy generic scan tool to look for codes, it can trip the VSC/TRAC lights. Toyotas are weird like that.

 

Is this an X-horse cable? The one I have won't talk to my '08 ECM, but talks fine to a '12 ECM and the wife's Scion. Not sure what the issue is, almost makes me want to get the Mongoose cable and upgrade my TIS subscription. The X-horse works fine for all the other ECUs onboard.
