Passlock Bypass Question....

[MJSilver00]

I am trying to install a remote starter on a 98 GA 2.4. I installed the same remote starter on my 00 with no problems, using the DEI555 passlock bypass module, but with this car it hasnt worked. The remote starter is working, but the bypass module isnt, so the car just shuts right off after you remote start it. I think I may have had one of the wires wrong (the directions say it needs to connect to the black "bulb check" wire, but there are 3 black wires in 2 different harnesses, and all of them test ground like the bulb check wire should). I did have it working to the point where you could program it and then start the car, but it would only work once and then the module would lose the code and not work again. If anyone has installed one of these on a 98 or can post a complete ignition wiring diagram (something that shows specifically which one is the bulb check wire), or even can tell me how to just remove the passlock feature all together, i would really appreciate it. Thanks for your help.

Also...to verify which one is the bulb check wire, and to verify my remote starter is giving me a ground pulse on the signal wire (the module needs this), is there a better way than hooking my meter to that wire and then to a ground on the car and looking for 0 ohms? This isnt working for me, but maybe its not the right way to look for a ground pulse. Anyway, Thanks again.

There is a black ring around the key cylinder. Coming off that should be
white (black/white) not used
Black (black) Ground reference wire
Yellow (black) resistance
Every car I've done uses the first set of colors. Make sure you use the correct wires on the 555L. Your 00 used the passlock II and this one uses the Passlock I. Do you still have the install booklet on the 555L? If not let me know and I will list the colors from that for ya. Peace, Lee

Hey, Thanks for the reply! I think I still have the book here somewhere, but I think I got those wires right. The problem is it needs to connect to the bulb check, or bulb test wire (ive seen it called both). This wire is in one of the two harnesses on the left side of the column. It said to verify which one is the bulb check wire you have to test it for a ground pulse that should be on only while the car is cranking. The only way I could think of to test this is to connect my ohm meter to a ground on the car, and then to the wire I think is the bulb check wire, and then see if it shows continuity (no resistance) while the car is cranking. None of the 3 wires in those harnesses showed this, but I think what im doing might not be the right way to check for a ground pulse. I need to either find out how to test for it the right way (also so I can verify my remote starter is putting out a ground pulse when it should), or I need to get a diagram or pinout chart that actually shows what harness and what position that wire should be in. Im not sure why this thing keeps losing the code every time I use it once, but I think its because I dont have the right wire for the bulb check, or my remote starter isnt putting a ground pulse out while its cranking the car. This is for my sister's car in NY, and I was hoping to finish it when I go home to visit at the end of this month. I would really would like to figure this out before then so I can make sure she has it for the winter. Anyway, thanks for any help!

I guess I don't know what you mean by a bulb check wire. If you mean the ground reference wire then I suppose if its black along with the resistance wire I would test it to ground, but instead of an ohm test I would use the continuity tester on a multi meter. Then make sure you cut ad hook up the resistance wires. One goes to the cylinder and the other to the cpu. If its backwards it won't work. Again though, check the book. Peace, Lee

yea I need to figure out how to set my meter for continuity test instead of using an oms measurement. I know this bulb check wire thing sounds strange, but trust me, I know exactly what you are talking about with the wires on the cylinder, and this is different. Its on the other side of the column all together. It is mentioned in those DEI instructions. Now if I could just get my hads on a pinout chart so I could make sure I knew which one it was. Otherwise Im thinking I will just try a different bypass module. I dont understand why this thing would lose its code all the time, and maybe this would be easier with just the dip switch kind of bypass where you set the code and thats it, those wont be able to lose their memory.

I beleive the only other module is the one that uses a factory key. Let me take a look at the book and my wire colors for your car and I'll get back to you tommorrow with an answer. What color are the wires coming off the passlock ring? Peace, Lee

I found what you are talking about. I don't do a lot of passlock I's. It says the bulb check wire is a 20 gauge wire in the ignition harness and should test ground while cranking. The continuity test is the one that beeps when you touch the two prongs together. Atleast that is what my multitester does. Good luck, Lee

[MJSilver00]

yep thats the one im talking about. I will try the continuity test, maybe just testing for no resistance was the mistake I was making and why I couldnt see the ground pulse. Im not sure if Im going to stick with the DEI for this car though. The few times I got it to work it forgot the code after the first time the car was started, then it had to be disconnected, reconnected and learn the code again before it would work one more time. It might have been defective but it has probably been too long to return it, so I think ill just get one of the ones with the resistors in them and you just test for your value, then set it and its done. Not that im saying the DEI doesnt work, in my 00 I havent had even one problem, but maybe I just got a defective one that time, or damaged it somehow when I was screwing around in there. Thanks for telling me about this continuity test thing, I checked and my digital meter has that feature, so Im sure that will help clear things up a lot.
