I have a 2000 Pontiac Grand Am. I have a Scytek 5100rs installed on my car. Every thing worked ok for a few months, but recently the car will not activate the remote start. I RMA'ed the unit and I just received a new one. It still is acting up. I bought a new DEI 556lw in order to see if that was the problem and to no avail the problem persisted. The problem I have is that will remote start if I auto learn set the DEI bypass unit, but will kill itself within 1 minute. I have reset all the settings to factory on the alarm. In one last desperate attempt I try to install a switch on the yellow passlock data wire. I was told if you cut the wire while the car is running it will disable the passlock. This did not work either. The car will just crank and thats it. So I was wondering if you guys could help. Thank you very much for your time.
seems like a bypass issue. Make sure you have your tach wire learned on the vehicle and test the wires connecting to the ignition switch. Make sure they give proper 12 v outputs to the ign harness. If a wire on the ign harness getting 12 v as a acc on a ign it can cause the r/s to fail. When installing a r/s up must duplicating what the key turning over does. Connect all your wires accordingly. if i dies after a minute then it can be the tach signal.
The actual model I have has three options of tach, gas, or diesel. I just put it on gas to avoid the tach.
I just saw the manual and you must be confused in regards to this. You either connect the tach wire and program or have it tachless in which it doesnt connect to anything. The manual statees that you must specify if its a gas or diesel vehicle to lear the tach wire. In diesel vehicles you would use a wait to start input for it to work. You must program the alarm for this function to work properly. Also you would have to connect the ground when running output wire to the bypass module in addition to power and ground. In your case the blue/orange wire from the alarm must connect to the ground when running input wire on the bypass(in most cases it is a blue wire).
