Question about 2001 Jaguar S-Type

1 Answer

Battery draining Battery drains when not in use. Makes no difference whether alarm is armed or not. The only other thing not working properly is that the horn no longer "honks" when locking or unlocking the car with the key fob. A minor annoyance but could be related to the battery draining?

    The horn works when activated on the syeering wheel but doesn't honk as it used to when locking the car with the key fob. Could this still be the problem?

    Definitely sounds that way to me

  • squee2001 Feb 09, 2014

    The wire break would be somewhere between the fob receiver and the horn relay

    Also just noticed that only on headlight "blinks" when unlocking the car with the key fob. The headlights and horn work fine when used normally, but doesn't honk when locking with the key fob or blink when unlocking. Should I be looking for a short or bad ground near the key fob receiver?

    There is a wiring problem between the fob receiver and the horn relay... simply put, the signal isn't getting to the horn when the fob relay is telling it to honk.

Check to see if there is a broken/bare wire on your horn circuit. That would explain the battery drain and the horn not working if there is a short.

SOURCE: Jag S-Type -intermitent fault where the remote fob does not work

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.

SOURCE: X type 2003 my key will not work when using the push buttons tried changing battery but nothing happens only way is manualy then I have to get in the car and turn engine on to disarm the alarm

1.)I would recommended that you ensure all key fobs are fitted with new batteries. ( Click here to see battery replacement guide).
2.)Get in the car and close the drivers side door.
3.)Put the key into the ignition and turn to position I.
4.)Wait 5 seconds
5.)Turn the key quickly to position II then back to I four times.
6.)You should hear a single chime.
7.)Remove the Key
8.)For each Keyfob in rapid succesion. Press any single button on the keyfob you wish to pair, you should hear a chime as each Keyfob is paired with the security system. After the chime do the next Keyfob.
9.)Check operation of each Keyfob.

Battery on 98 Ford Expedition doesn't hold charge

First thing I would do is have someone qualified disconnect the alarm and stereo and start over.
Chances are you have circuits cross-connected and something is draining the battery.

1985 cadillac eldorado battery drain

The security light is supposed to flash, it indicates the system is armed, the system is functional in my opinion, why do you think it isn't? It is not the cause of the drain unless the car sits for months. Check for vanity lites in the visor left on or other interior lights.

My 1994 Jeep Grand Cherokee Laredo wont start, everytime I try to start it, it makes this loud noise like a buzzing sound, and then the security light starts flashing and the brights light starts flashing...

If your battery has not been drained, try unlocking the lift gate or the passenger side door. That should disarm the alarm. You may need to get a jump if you're getting the flashing lights.

Another thing it does is to shut off your fuel pump. If you get it started after trying the above procedure, the issue is definitely your alarm system.

It is armed whenever you normally leave your car (using power locks seems to arm it on my 94 GCL.

There is a permanant disarming procedure on FixYA but it is pretty radical -- you have to find one of the wires that sends the signal to the alarm system from one of your door locks and ground it.

Is there a way to disable the alarm to see if that's draining the battery on a 2000 740i?

No not unless you want to mess with he wiring which is not advisable as you are just guessing what the issue might be. The alarm and other systems are not designed to draw enough power to drain the battery unless the car is idle for a few weeks or more.

The best thing to do is to get the car to a reputable auto electrician so he can test which functions on the car are draining the battery beyond normal current draw when the car is idle.

Have you checked for faulty or sticking power window switches. Just one faulty switch will allow power to the electric motor and the battery will drain virtually overnight.

Do you know if the alternator is functioning properly and supplying power when the vehicle is running? Has it been tested? If it is faulty the battery will be drained when the car is operated.

If you retain this brand of vehicle I'm afraid you can expect to experience quite a few electrical problems.

If i leave the battery connected overnightit

NO the alarm does not draw that much current for it to drain the battery. Look for a light bulb like the one under the hood or the glove box. The other thing to is if you have a rear wiper for the window, it's been know for the wiper arm not to return full back to it's neutral position due to corrosion at the shaft and the motor will draw current trying to pull the wiper arm back to the neutral position. Try pulling the fuse to the rear wiper motor from the fuse box and see if the battery stops draining. Good luck and hope this helps friend.

My 1974 Buick Apollo has a short circuit in the

Is it a short or a drain on the battery? It's important because a short will blow a fuse and a drain will just deplete the battery.First ck your charging voltage at the battery posts. should be between 13.6 and 14.2 volts. Lower the volts the higher the charging ampereage.. AllOk? , Now remove the ground cable at the battery and put a test ight between the post and cable. The prob on the cable and the clamp lead on the batt post. If there is a drain the test light will come on. Make sure everything is off and the doors are closed.. If you have an alarm system, takte its fuse out temp.. If the lite does not come on, put the alarm fuse back in. If the light comes on, There is your drain. If the battery is properly charged, it should tolerate the alarm.. Good luck

97 vw jetta w/aftr mkt. alarm drains battery and disarms on own?

My friend you are faced with a catch 22 problem. The first thing I would like to know is, who installed the alarm system? Did you do it or was it professionally installed. If it wwas professionally installed I would go right back there and discuss the problem with them. It very well could be a defective unit. If you did not have it installed professionally I would disconnect the alarm and see if your battery still get's drained.If so, then the alarm is not the culprit, and you have some hunting to do. If not then you have some testing to do.Next what type of alarm is it? Try to google it. You may be able to find a trouble shooting guide to assist you. I know that you said you just replaced the battery, but the alarm very well may not be the culprit. It could be many other things as a loose fanbelt, bad diodes in your alternator, or some other componet draining your battery.
