How do I reset electronic Immobilization. The light is flashing

The car will start for approximately 2 second and shut down. I noticed the electronic immobilization light flashing on console. I tried all the keys we had and it would not notice any of them. Everything was fine there was no indications that were leading to this. One day great the next day it had no idea who's key it was. Is there a way to reprogram/repair this without having to tow to dealer? Thank You

You need a smart scanner like VAG-COM to re-program. Let the dealer do it.

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

SOURCE: My jetta won't recognize the key

I have had this same issue ever since I purchased the car new in 2000. It seems to be a very intermittent issue, but I found that when it occurred, it was typically damp and between 40 and 50F.

In any case, the dealer was not able to diagnose and fix the problem. I did get them to give me a 4 digit pass code for the immobilizer. This pass code is entered by using the clock adjust knob and the odometer reset button. Once the pass code is entered, the car will start. However, this is not a permanent fix as you may need to enter the pass code again should the immobilizer activate.

Sometimes the Jetta will start after 5-6 trys when the immobilizer is activated, but if I crank anything past 10, I usually resort to the pass code.

I am searching today for solutions since I have needed to use the pass code twice in the last 4 times that I have neede to start the car, and the weather is perfect.

Car sat in parking lot for 3 days, with a lot of rain. Upon start up Check Engine & VSC began to flash. Car ran normally for 2 miles. Pulled over shut down car, waited 10 seconds re-started engine...

It likely had water on the ignition system. The check engine light will flash for misfire. The VSC light is on just because the check engine light is on. You likely have it dried out now and its fine. You just need to clear the codes. Autozone will do this for free.

I had my oil changed in October after the "oil

Try this procedure and let me know if this does not work;

Turn the ignition switch to the "On" position but do not start the engine.

1. Press the Trip/Reset button until "Setup Menu Hold Reset" is displayed.

2. Then press and hold down the Trip/Reset button for approximately 2 seconds until "Reset For System Check" is displayed then release the Trip/Reset button.

3. Then immediately press and hold down the Trip/Reset button again for approximately 2 more seconds until "OIL 100% RESET IF NEW" is displayed then release the Trip/Reset button.

4. Then immediately press the Trip/Reset button once to display "HOLD RESET IF NEW OIL" then release the Trip/Reset button.

5. Then immediately press and hold the Trip/Reset button again for approximately 2 seconds until "OIL LIFE SET TO 100%" is displayed.

Turn off the ignition switch, and then start the engine to verify that the reset procedure did work, and you might have to repeat the procedure if the Trip/Reset button is not pushed fast enough, or it is not held down long enough, or it is held down too long during the reset procedure, and it may take a few attempts to be successful.

My abs light is on and my car shut off and wont come back on


Your ABS light is not directly related to your engine and would not cause your vehicle to shut down. Therefore, we need to have the Diagnostic Codes extracted from your vehicle's computer, before we can examine likely causes.

Assuming you cannot extract codes from the DTC connector, I can offer a different method which applies to some late model Nissans...


1 Switch the ignition ON (but DO NOT start the engine). 2 Wait 3 seconds. 3 Within the next 5 seconds, "fully depress - then fully release the accelerator pedal" 5 times (i.e. once per second). 4 Wait 7 seconds. 5 Fully depress the accelerator pedal...and hold it down for approximately 10 seconds. 6 The "ENGINE CHECK" Light should begin flashing. Fully release the accelerator pedal. 7 Read codes as described in the Code Format Description below. Code Format Description - the fault code will be in one of the following Code Formats below: The code is made up of four groups of flashes each representing a digit. A long flash indicates the 'thousands' digit. 'Hundreds' 'Tens' and 'Ones' are groups of short flashes respectively. A long pause separates each trouble code. A shorter pause separates each group of flashes Please note: A '0' digit is indicated by 10 flashes with this system.
Or... Each code is made up of two series of flashes. The long flashes indicate the 'hundreds' digit, however can be a value up to 13 (eg 13 flashes = Thirteen Hundred). The short flashes indicate the 'ones' digit, however can a value up to 15. A long pause separates each code sequence. Once you obtain the codes (or have someone do it for you) from your ENGINE CHECK LIGHT, post the codes here are someone can assist you further. PS: Your first priority is to get the vehicle mobile again. We can then deal with the ABS issue separately. Cheers,

Change oil soon light. how to get it to shut off

Answer The "change oil" light on a 2001 Grand Prix is reset by pressing the gas pedal three times while the vehicle is in "accessory" mode:

1. Turn the car off.
2. Place the ignition key in the "on" position, without starting the car. That is, turn the key forward to the place right before it fires the engine.
3. Place your foot on the gas pedal and press it all the way down three times, waiting approximately one second between presses.

If done correctly, the "change oil" light will flash repeatedly, and will then reset.

Please note that it is rare to do this successfully on the first try; if it does not work, turn the car off and try the procedure again, varying the wait slightly between pedal presses at each attempt
