Auto Zone helped me and it used a 3157 sylvania bulb when the manual said to find a 33 … 57. I then did the reprogram procedure described at the beginning, off, start, run for 10 min repeat and after the 3rd time I tried to start it and nothing happened then I put it in neutral and it started I then put it in park and tried again and it started! If you did everything right it should start. You don't even have to replace your key. I have tried both the 10 minute reset as well as the full 30 minute re-learn - none have worked. This is definitely an issue. There are other people on here that you can read to tell you how to do that 10 minute thing. Next, arrange one or more resistors in a chain so that they add up to the value measured while cranking the starter.
You can also reset the alarm system by disconecting the power to the alarm it's self if you know which wires are for the alarm. Leave it that way for 10 minutes. Also, I saw a tutorial where it seems the guy was saying to place resistor in yellow wire. The locks, windows, radio, and lights will all come on but the car wont make a sound. The loss of communications usually means a power or ground loss, which I would suspect would be the B. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode.
There are many variations of the system going back to the early 1990's. This could save me 10 minutes every time it happens if it continues to work! The keyless entry remote and the ignition key are required to properly reset this system. I would have them replace it with a new one and see if that makes a difference. It is possible for a passlock system to disable injectors, but not in the Impala. Now the only issue I am having is it won't lock the doors.
Hold the other probe to the ignition side of the wire you cut in the earlier step. Passlock Operation This Passlock sensor is located inside the ignition switch and receives a reference voltage 5 volts from the Body Control Module when turning the key on. Once that is done, be sure to tape the exposed cut wire that leads to the ignition barrel. Obviously nobody is monitoring this site anymore. If you have performed these steps correctly, your Passlock system will no longer give you any problems! I told them that this is a design flaw and does not work as intended and that many other people are having the same problem. The lady who answered was probably in India from her accent and all she could do was refer me to the local Chevy dealership where I had already been. The post included the following procedure: Get in the car, shut the door, ignition on, ignition off, window down, window up, lock, unlock.
I bet at least one or two are burned out. What planet are they on? Please let us know what you find. Passlock only disables the injectors, it allows spark and fuel pressure. Without a scan tool you may have momentary starter interruptions while history clears itself. Today the car would not start and lo and behold I put it in neutral and it started on the 1st try! If your car cranks, I have a strong suspicion it is not the passlock that is the cause. Anyway, time for me to find a new ignition switch and see if that is where my problem lies.
Works every time he says. I did fine made it to Atl. Give it a try it cost nothing. The scan tool must stay connected until all of the transmitters are programmed. In addition, this procedure will need to be done anytime the Body Control Module loses its memory. Have you read the dtc's? What you have to do is from your ignition switch there are wires plugged into the sensor on top of the switch. Sometimes it took up to an hour to get mine to start.
Although i did try the white and blue wire. It is so prone to failure that it is not worth having in my opinion. If it cranks but wont start, but you have fuel and spark, I would guess it is air related. I got it going and went to the truck stop about 45miles down the rd too ask mechanic to tighten it with the proper tool. It sure does appear that way. I was going to beat my car with a bat! This is what I had to do.
I pulled over and in ten min it started and I made it to the next exit then it shut down on the middle of the intersection. Have a pro load test the starter to seeif it is drawing tomany amps. I can consistently start my car first try if I disconnect the - cable for 10+ minutes. I jumped starter and cranked engine, but it wont fire. You may not even notice it. Any help greatly appreciated bj Hey Brian Can the relearn process be done anytime or just when the security symbol shows up? What goes wrong with Passlock? The system resets itself every 10 minutes, so if it is the passlock, you should be able to start the car eventually after 3-4, maybe more attempts with 10 minutes between each. Inline it to the wire responsible from the switch of ignition with silder and heat shrink and try the same key, being careful not to fuel lockout by trying too many times turning a 4 second wait into continuous frustrating 9 instead of ten min or more intervals.
Start the engine, the vehicle has now learned the voltage reading coming back from the ignition switch. Here also is comments I saved almost a month ago that had me clean all contact points. I think a toggle switch would be a great choice. Paslock can be replaced cheaply with an ignition part. Put it back in and problem was fixed and havent had a problem since. The passlock sensor and the ignition switch are in series.
Make sure the battery if fully charged because this procedure may take up to 30 minutes and you cannot start the vehicle during this time. Lol that is called a placebo my friend. Or do i have another isssue? We are interested to see what it is. I think that you will have to use it once the codes are cleared i. Anyway after poking around the dealers and asking questions they told me unfortunately there is no recall on this reoccurring problem of passlock lock out on my truck.
