triple tested all the wiring, power, ground, data, with multimeter and all seem fine. this is the third truck i am installing on. had lots of dificulty getting the first two too program but they eventually did. this truck i flash the modual, istall it in vehicle with program button, yellow, press five times, wait for yellow light to flash then stay on, insert key and turn on, the yellow and red lights come on together and stay on for about a second then start flashing continuouslly. this with the recomended software 70.30. i have another module flashed with the latest, 70.31 beta. with this one the unit acts like it should, with the key on the yellow light goes out and the red one on, turn the key off and remove, wait five seconds and reinstall, turn ignition on, the blue and red lights come on and flash, then the yellow flashes, then the yellow goes out and that is it, nothing else happens. but at this stage i can go through the decription and it says complete, unit will still not start the vehicle. push the lock with the doors closed 3 times and no lights on the module. even with the unlock before option. really racked my brain and i can not figure it out, any suggestions will be greatly apreciated. i have two or three more of these to do.
