Panasonic CN-HDS700TD touchscreen car audio system comes on when you start the car but becomes unresponsive after about 10 minutes,shuts down only to reboot again and cycle repeats.please help.

could be fuel pump or in the ignition system...many things it could be..

The Passlock system is notorious for failing. There are 3 different parts of this system that can shut down the car and activate the Antitheft security system. The problem will be one of these 3 things. The key. the ignition lock cylinder, or the TDM. The easiest one is the key. The key will either have a small black chip in the key shaft or a transponder hidden in the key head. If there is a chip, they are known for wearing down and not reading correctly. Try wiggling it, cleaning the chip with alcohol, and taking all other keys off the key chain because it pulls on the key and causes problems. If you have no chip and instead a transponded key, (it will have a little "+" sign by the plastic) you can try performing a relearn procedure. It goes like this.




1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.
If that doesnt work, you will need to start replacing parts. Like i said, there are 3 parts. The key, the ignition lock cylinder, and the Theft Deterrent Module (TDM). all of these are involved in the Passlock system and could be responsible for shutting down the vehicle. And trust me they are all expensive. I always share this link for this problem because there is so much information on there and will be helpful no matter what you decide to do. If all else fails, there is PERMANENT FIX for this problem. You can bypass all aspects of the system and never worry again. That is also on this link.

Yes. I have a 2006 Jetta and the cooling fan (the one on the radiator) runs after I shut my car off. It's to continue to disperse the heat and cool things off. No worries. I would watch it and make sure it does not become a problem tho.

The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start.

Have fuel pump checked out

does check engine light come on.check for fuel and spark when it doesnt start

Do you get a check engine light? If so, read the codes with a scanner and chase down the clues. Does the PCM match the car and engine? Was the original engine a 3.8L? 5 to 10 minutes is not very long for an engine to cool down appreciably. Hopefully, the PCM codes will indicate whether the missing problem is fuel or ignition related.

try this
PASSKEY LOCKOUT RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.

Your car is equipped with a system called PASSKEY standard on all GM cars and light trucks, try the following procedure to reset the system, the battery being dead will trigger the system.

sounds like a tipical crankshaft position sensor will fix your car
