Passlock
Ok I've finally had it with my blazer and this stupid passlock. I've changed everything the pcm the bcm the ign switch the multifunction switch and I'm still having a no start situation once and a while with it. I've done the relearn thousands of times and it helps for a day. How the hell do I eliminate the passlock? Theres gotta be a way to eliminate it.

What about the Passlock Sensor at the Key? It senses the turning of the key and sends the signal to the BCM. Sometimes the wiring (3-wires, Yel, Org/Blk, Red/Wht) gets damaged or the sensor fails. |
Isnt that part of the ign switch?

You should check for Passlock "B" Codes. |

The 3-wire harness is the one. |
If you have decided you HAVE to have passlock disabled i believe PCM4Less will do it as part of a tune.... beyond that I'm not sure. But it CAN be done.

Replace lock cylinder and keys, I did that on our 02 impala and it works every time now
Just have to do the relearn long procedure. This is not the ignition switch it's the key cylinder |
I'm geting no bcodes ive got a scanner that will read them. I replaced the passlock sensor again it working fine for now so im getting rid of it before this crap happens again out of all the blazers and s-10 trucks ive owned this one by far has been the biggest POS. Thanks for all the help guys.
