I was driving down the hwy the other night and hit it to pass some slow people. When I got around them, I noticed that my check engine light had popped on, and then a few seconds later, my ATTS light popped on too. The car is running fine, but this isn't the first time this has happened to me. Anyone know what's up?

 

Could be a million different things. You should check to see if you're throwing any codes....

Can't check codes until this weekend, but that's definately the plan

 

does it keep happening? does it go away if you reset your ECU?

This is the second time it has happened, my boyfriend has an OBDII scanner tool and we just erase the codes and the lights go away. It didn't happen immediately after we erased the codes the first time, but obvioulsy it does keep happening. haven't tried to reset the ECU.

Also, I have a vtec controller.....could there be something there that would be causing the lights to pop on?

 

just a VTEC controller? or a VAFC or something like that? check your wiring on it...if its not completely covered in electrical tape or whatever you like to use to cover wiring then it could be shorting out and throwing codes. What code are you getting?

It's the Fields VTEC controller and I don't remember what codes we got the first time this happened. I'll let ya know on Friday what code it is.

I'm getting the code 1259 for the lights. know what that is or direct me to where I can find it?

 

its online just search for it, that does sound familiar though....

 

This link to a site with list of codes might help, also below another list of codes found.

yeah, i'm actually on that board but that didn't help much. Thanks though. When searching on the internet I found that the code was "immobilizer to PCM signal error".....anyone know what that means???

 

llights code, never heard of that before
