I think I'm having a passlock issue. I was installing my Sirius radio the other day and then after my truck wouldn't start. I checked everything I can think of spark, gas, fuses, everything looks good. I tried doing the security relearn procedure but that didn't help either. So my question is is there a way I can disable or check passlock in EFI somewhere? Any help would be great.

 

i know in HP tuners you can ditch the passlock. but yes you can remove it to help aid in what your doing just not sure if EFI has it

 

I plugged my EFI live and read the DTC's. One error come up C0309 - Motor A/B Circuit High anyone have any idea what this means?

 

Did you replace the stereo all together with one that has Sirius capability or did you just hook up a Sirius radio to the factory radio?
If you replaced it all together. Did you splice into the factory harness or did you use a plug n play adapter?

 

do u have alram and remote starter?
cuz factory passlock should not give you a problem after u install sirus.
how did u install sirus? u have factory or after market head unit?

 

I just added the external Sirius radio.

I do not have a remote starter. I have an after market head unit with an external Sirius radio.

 

ic~ are u using aftermarket harness to power up head unit? where did u tap+12v power from to get to sirus?
u might touch ignition line or something.

 

What is the security light doing. That will tell you if it is passlock. A sure fire way is a start and die condition. Need a little more info to point you in a direction.
