Hi everyone, I had a 2012 Toyota Camry w/o smartkey, I try install R/S over the weekend and everything seem to working just fine except when I try to r/s its doesn't crank, but the dashboard light and everything is on then turn off after a few second. I meter the starter wire (purple) when I r/s it doesn't get any voltage reading at all, I just wondering what was the problem?

It might help it you list all of your connection from the unit to your car. I don't have a install guide for this unit, but are all three of the heavy gauge, FUSED wires, connected to a 12 volt source?When all else fails, Read the Instructions

yes (H4) 8 thick-gauge wires (relay pack)     vehicle wire H4/1 - pink/white(+) ignition 2 / flex relay output        - pink H4/2 - RED / white (+) fuse (30a) ignition 2/flex relay input- green 12v H4/3 - pink      (+) ignition output        - black H4/4 - red       (+) 12 volt input - green 12v H4/5 - orange    (+) accessory output       - white H4/6 - red       (+) 12 volt input - green 12v H4/7 - green        starter input (from key switch) **    - not use H4/8 - violet    (+) starter output (to starter)  - blue

I just realize the car has 2 starter wire which is start 1 (blue) which I make connection to and start 2 ( lt green) ? do i have to use both wires for it to work?

Most likely. You will have to use the (-) Starter from a different harness with a relay for the second starter, since you have used the flex relay output for the second ignition.When all else fails, Read the Instructions

I kind of got the idea, but one thing I don't understand is that the starter wire from r/s not sending voltage? even though I didn't have the second starter wire hook up, at least the voltage present...right?

It would seem so. I don't have the documentation for that model, so not sure what wire is for what. Just kinda going from a photo of the unit and the past wiring scheme from DEIWhen all else fails, Read the Instructions

Kind of a late response but I had the same issue with my 2007 Accord. There is only 1 starter wire in my car. The Purple wire would only go to .01 voltage during RS. I reset my module and reflashed and it finally cranked. I think it has to do with Virtual Tach. The firmware seems buggy though. Sometimes I don't get the light flash and other times the horn doesn't honk. I'm running D2D so I didn't connect any of those wires directly. They should work like OEM through CAN.
