Any ideas on why my OBD II won't be read?
I plug it in, and it says "err 1".
It's an Innova 3030.
Or is there certain types that only work on certain cars?
I thought all OBD II scanners work the same.
Help me out. Thanks.

 

Oh I even took it in to a shop and they couldn't get a reading either.
They both had the same results.

 

Put your car on a trickle charger or swap the car battery for a new one. I had issues getting my ODB II scanner to work before and its because the battery was uber low.

 

alright will give that a try.

 

Tried it. No luck...
Any other suggestions?

 

Are you sure you have stock ecu installed? no ems??

 

have you checked your fuses?

 

I do have a apexi powerfc installed...
Does that change anything?
Checking the fuses now.

 

I'm not sure if obd2 is observed by law in Guam.
Make sure the pin fitment is secure. Look for bent or corroded pins in the obd2 dlc.
Make sure both grounds work, and check for battery voltage at pin16

 

Its your power FC. it has no ODBII output

 

power fc not obd ompliant

 

That small detail def. changes everything. Its the Power FC. Have you tried calling Apex i about this?

 

I have called and emailed. No answer or reply.
Do I really need this in the car anyways?
I bought it used. And it came with the powerfc and a safc ii installed already.
Let me know. Thanks.
