Question about 2012 Chrysler Town and Country Touring Passenger Minivan 3.6L V6 FFV 6-speed Automatic

1 Answer

Periodically, I get the message "key not detected" when I want to start the car. I have my foot on the brake, push the button, take my foot off the brake, do over, and over, and eventually the car will start. Also on occasion, I am outside with the key in my pocket, and the door will not open, over an over, I have taken the key out of my pocket, and eventually the door opens. Today, while I was driving home, there was a message "no key detected" while driving I took the key out of my pocket, no change in message. When I arrived home, I stopped the engine, and re-started, all was OK. I had taken this issue into my dealer on a previous occasion, within the first year of owning the car, and they said there was nothing wrong. I do believe there is something wrong, and soon I will be leaving on our Winter Holiday, and will be away from home for 3 months. Is there anything that has been found out about this problem.

SOURCE: battery goes dead on 2004 pacifica

There is obviously a draw from somewhere, and if your dealer doesn't have a mechanic who knows how to narrow it down to the circuit causing the problem, then I'd question there ability. With that said, when all else fails, you simply remove negative connection off battery first, then positive. Take a 12 volt test light & secure one end to the + clamp or connector, and the other end to the battery+ post. Now connect your negative back up to the battery as it was. If that test light, lights up, there is a draw. It will be brighter, the more draw there is. Your going to have some, just from your radio memory alone, but now comes the fun part. All you do is pull the fuses one at a time, if light goes out, or dim's you've found a draw. When you have a real hard one to narrow down, you make sure you know where they all go back to, whether by your map at fuse box, or your own notes, and you pull them all out, and light should go out for sure, if not, there is another circuit or panel, or relay drawing the current. If it goes out, you start putting them back in one at a time, and when the light comes back on bright, you found the circuit. Mark that one down, pull the fuse back out, light off, now do the rest that you haven't checked yet, just to see if there is more than one draw causing the problem, if there is, mark it down, pull it out & continue on until all done. Now you/they narrowed it down or isolated the circuit causing the problem.

SOURCE: periodically the crossfire won't start.

This sounds like one of those interesting problems. What you are going to have to do is find a light bulb type of electrical tester, and a schematic for the wiring on the car (or get a mechanic to do it). When the problem comes up again, you have to find where the power to the module is not coming through a weak connection. It is something that warms up and then breaks connection.
The first thing to do is change the fuses for the engine controls. Fuses are cheap and sometimes they develop a crack that opens when they see a rise in temperature from a heavy electrical load or warm or cold weather changes. Other things that cause problems are the wires that connect to the battery, and splices in those wires which are usually hidden inside a bundle of wires. Also inspect the connectors that hook up to the engine module and make sure the pins are not pulling out from tension in the wires and other defects.
You said it doesn't turn over, so also check the connections at the starter. Sometimes main power is routed through there.

What causes an error mssage of: Restart now or key is needed in a Ford Edge.


Driving 4. Start - press the START/STOP button (for any length of time) while applying the brake pedal. Note: The indicator light on the start button will illuminate when the vehicle is in on mode and when the engine is started. There may be areas inside your vehicle where the IA key is not detected. If the message NO KEY DETECTED appears on your message center when you press the START/STOP button, it may be necessary to move your IA key to another area within the vehicle. The IA key may not be detected near the roof (between the driver or passenger sunvisor and the roof, or in the overhead console area) or in the extreme corners of the rear package tray, near your audio speakers. It is not recommended that you stow the IA key in these locations. If you move the IA key to a location where it has been detected before and you still see the NO KEY DETECTED message, your IA key's battery may be low or you may be in an area with excessive radio frequency interference. If this occurs, you can use the back-up method to start your vehicle (see below). Back-up method of starting: Your IA key uses a radio frequency signal to communicate with your vehicle and authorize your vehicle to start when you press the START/STOP button and apply the brake pedal. If excessive radio frequency interference is present in the area, or if the battery in your IA key is low, it may be necessary to start your car by inserting the IA key in the back-up slot, located at the front of the center console storage compartment. Insert the IA key into the slot with buttons facing down and with key ring out. After inserting the IA key into the back-up slot, use the START/STOP button and brake pedal to start your vehicle as usual. The vehicle should respond normally as long as the IA key is in the back-up slot. Once the vehicle is started, the IA key can be removed from the back-up slot, if desired. Fast restart feature: The Fast Restart feature allows you to re-start your vehicle within 20 seconds of switching the vehicle off, if a valid IA key is not present when the vehicle is switched off. When you switch your vehicle off without an IA key in the passenger compartment or 238 2012 Edge (edg) Owners Guide, 1st Printing USA (fus)

My vehicle is a Mercededs C200 compressor yr2002 The key in the ignition is not turning to start the engine as the steering lock is not unlocking. What is the cause and solution?


With your foot on the brake try and move your gearshifter in to the neutral position it may start in nuetral. If not check around the switch some Mercedes have a small safety button that needs to be pushed to remove your key sometimes you can try pushing the button and moving your switch several times and it will unlock. Those are just a few things to try, good luck.

The parking brake in my chrysler pacific is stuck. how do u release it?


Is it a "stick" in the console between the driver and passenger seats, or is it a pedal you push down? If it is in the center console, try starting the car, putting it from park into NEUTRAL with your foot on the brake, and pull up on the stick a little while pushing in the button. If the button goes in, push the handle back down, put the car back into park, and take your foot off the brake. I'm not real familiar with the Pacifica, so a description of the parking brake would help.

The abs light is on and the brake light comes on and stays on even if the van isn,t moving and foot is not on the brake peddle


It is probably a warning that you are low on brake fluid. As your brake shoes wear out you need more and more brake fluid to push them against the rotors so you should always periodically check your brake fluid and keep the resevoir full.

There is a sensor near your brake pads that tells the electrical component in the bush button that you are pushing in the brake. I was having the same problem and just had mine replaced.

2008 s80 how do i reset maintenance overdue


Put the key in the slot and push it in. With one hand press and hold the odometer reset button on the instrument cluster. With the other hand press the start button one time. Pause for one second and then push and hold the start button (with your foot off of the brake pedal) until all of the dash lights come on. Continue to hold the odometer reset button until the yellow triangle flashes. It will flash four times, release the button before the end of the fourth flash. Then turn the car off and remove the key. Reinsert the key and start the car. The light should now be off.
