5902 remote start constant start mode

If everything is working correctly, I should NOT see 12 volts on the purple wire, right?

Syl20rochon is also correct; you can either cut it which is what the book says and that will provide what I stated above. Again as I said before check your wiring. Remove the fuses and check for discontinuity between the RED / white, red.black and purple. That will tell us if you have a faulty unit.

Howie is right, check all you connection and compare to the picture....Sylvain Rochon

OK, sorry, had to take a break from this. I reinstalled the ground, then replaced the fuses one at a time. Before I replaced any of the large wire fuses, the headlights were already on. When I replace the solid red fuse, I can hear the truck systems come on, but no cranking. When I replaced the RED / white fuse, it sounded like more systems came on. When I replace the RED / black fuse, the truck starts cranking.

I also checked some continuity with the brain removed. I checked the purple wire vs. all others. The only one it had continuity with was the green. I think this is probably as it should be? Thanks everyone.

disconnect your r/s module and test the heavy gauge wires...I'll try to be as clear as possible (Use a voltmeter, multimeter of test probe) 1= 12v, 0=0v key position            off      acc     ign     start   ign      off Ignition 1 Pink          0        0       1        1      1        0 Ignition 2 Pink/white    0        0       1        1      1        0 Accessory Orange        0        1       1        0      1        0 Starter    Purple        0        0       0        1      0        0 *** Temporarily reconnect the starter wire back together and disconnect the large green wire*** Please confirm to me that you are getting the above chart.

Your chart is clear. R/S module being the Key-Override-All, or are you just talking about one of the smaller plugs that go into the brain?

I would leave main harness (H3/1...9 except for 8)(Pink/black is not used and should not be plugged) plugged in with the 12v(H1/2). Ground wire(H1/5)and BLACK/ white(H2/18). I would disconnect all others (park,brake) including the bypass to see if the module still powers on the ignition switch by itself.Sylvain Rochon

I haven't checked everything yet, but Pink and Purple both show +12 even with no key in the ignition, and the KOA disconnected. Also, the headlights come on immediately when H1 is connected.

I got a little sidetracked on this Number 1 harness. Do these values sound remotely correct? This is with the brain unplugged, just measuring the voltages directly from the harness.
