Hello,

All of the wiring diagram for 2004 Toyota Sienna that I found on the net, says UNLOCK is Blue. But this wire show 0V at all time. Does anyone know this wire. I found the lock wire ( LIGHT GREEN ) It shows about 10V when I press lock it pulse to 0V and back again to 10V

I also try to use the priority unlock feature from Compustar 2WAS module. But I don't know how to wire them up.

Need help please

Thanks In Advance

Are you pushing the unlock switch on the door to test the wire? that is not the correct way. You need to meter the wire while turning the key in the drivers door to unlock. A single pulse on the wire will unlock the drivers door, a second pulse will unlock the other doors.

You can also use the passenger door key cylinder wire for unlock, which only requires a single pulse. It is blue / YELLOW (-) in the passenger kick in a 12 pin plug.

Yes, I used key to rotate but I don't see any pulse. the BLUE wire always shows 0V, and I ckeck all other wire in that connector only wire shows 12V at all time even when I rotate the key.

Thanks for response

power lock lt. green - trigger drivers kick panel

power unlock blue - drivers kick panel

p.s. jworm is correct about how to test for these wires. I am sure he did not mean to upset you. Just trying to avoid common mistakes
