Typical draw for parked car is around 100 milliamps

Suggest that you disconnect power to the car for several minutes. Reconnect the battery. The object is to reset the body electronics module.

If the computers in the modules get a glitch they can cause a drain. By cycling the power, disconnecting battery, they will reset to factory settings. Reported it can take up to 20 minutes for the circuits to drain before you can reset!.

Jeep Grand Cherokee WJ Electronic Control Modules

the following web site does a great job of explaining all that is going on. What appears to be simple to troubleshoot is not so easy. He comments about delay before sleep are important. Testing after overnight may result in a different drain rate. Make sure that your battery meets specifications. In 2000 the drain rate may be relatively high and the reserve capacity of your battery low.
Hope this helps?

The ignition is computer controlled and has no adjustment of any kind. That said you need to run a scan through the diagnostic service port under the dash to see what fault codes are stored that may explain what is causing this. You may also have an internal engine problem like a timing chain failure or other issues.

dash radio,
stock radio
is it the single deck model or the multi deck option/
photos work best, for all that.
if that is the only failure, (radio works)
then the cd is jammed, can be cause by many things.
broken CD
parts of previous cd broken parts inside jamming it
or its far worse.
it will need to be dismantled, to fix it.
unlike computers, there is no tiny hole there for paper clip to eject it , emerg. mode)
so repair on the old one, labor and parts would exceed cost of upgrade, why not go CD free, use memory stick, with your CDs ripped to MP3, files, and move on,....
the last CDs will be sold in walmart.
and the isle keeps shrinking and soon to be like VHS videos, a memory.

First remove and clean battery cables and battery posts with a wire brush or sand paper. Make sure battery is charged and check to see if it starts. Then check battery condition and charging system. The problem could be cables, battery, or alternator. Check them in order and repair or replace as needed. Check cables, battery, belts(tension and condition), and charging system in order. Do this because bad cables will give false readings for other tests and so on.

why not do what it says to do?
not sure what you saw there are many coolant errors that are possible on this car.
but if RAD level low , that means ...
the side bottle (plastic expansion tank) is low.
it has a sensor there, if the coolant levle there is ok . (i bet its NOT)
then replace this sensor, or the wires fell off.
or clean it , if it fibs. clean it, and now works.

the parts are all shown in one or 2 places

If you have blown the bearings, eventually they melt and plug the oil holes, so that the oil pressure pegs. Don't drive it at all.

The brake light switch will be open circuit when the brake pedal is not depressed and will have a closed circuit when depressed. IE/ switch off when the pedal is up and switch on when the pedal is pressed. You will need a multimeter to check or you can use a 12 volt globe or voltage tester. Power on 1 side of the switch when off, both sides when closed or on.,

Is it leaking externally that you see? If so, you may have leaking freeze plugs on the engine block or cylinder head. If it is not external, then check the exhaust. Are you getting white smoke? Does the exhaust have a sweet smell? You could have a cracked cylinder wall, cylinder head, or blown head gasket. Check the floor inside the vehicle. Is it wet anywhere, especially passenger side front. It could be a leaking heater core. If all else fails, have the system pressure tested by a mechanic to find the source of the leak. Some can be very hard to detect.

WJ jeep year 2000
ill read the book for you.
veh. theft security chapter.
chapter 8q in the FSM.
page 7 , "customer method"
ill see if i can paste it here, (found it in 10 seconds)

quote, real FSM
The Customer Learn feature is only available on
domestic vehicles, or those vehicles which have a
U.S. country code designator. This programming
method also requires access to at least two valid Sentry
If two valid Sentry Keys are not available,
or if the vehicle does not have a U.S. country code
designator, the Secured Access Method must be used
to program new or additional valid keys to the SKIM.
The Customer Learn programming method procedures
are as follows:
(1) Obtain the blank Sentry Key(s) that are to be
programmed as valid keys for the vehicle. Cut the
blank key(s) to match the ignition switch lock cylinder
mechanical key codes.
(2) Insert one of the two valid Sentry Keys into the
ignition switch and turn the ignition switch to the
On position.
(3) After the ignition switch has been in the On
position for longer than three seconds, but no more
than fifteen seconds, cycle the ignition switch back to
the Off position. Replace the first valid Sentry Key in
the ignition switch lock cylinder with the second
valid Sentry Key and turn the ignition switch back to
the On position. The second valid Sentry Key must
be inserted in the lock cylinder within fifteen seconds
of removing the first valid key.
(4) About ten seconds after the completion of Step
3, the SKIS indicator in the instrument cluster will
start to flash and a single audible chime tone will
sound to indicate that the system has entered the
Customer Learn programming mode.
(5) Within sixty seconds of entering the Customer
Learn programming mode, turn the ignition switch to
the Off position, replace the valid Sentry Key with a
blank Sentry Key transponder, and turn the ignition
switch back to the On position.
(6) About ten seconds after the completion of Step
5, a single audible chime tone will sound and the
SKIS indicator will stop flashing, stay on solid for
three seconds, then turn off to indicate that the
blank Sentry Key has been successfully programmed.
The SKIS will immediately exit the Customer Learn
programming mode and the vehicle may now be
started using the newly programmed valid Sentry
Each of these steps must be repeated and completed
in their entirety for each additional Sentry
Key that is to be programmed. If the above steps are
not completed in the given sequence, or within the
allotted time, the SKIS will exit the Customer Learn
programming mode and the programming will be
unsuccessful. The SKIS will also automatically exit
the Customer Learn programming mode if it sees a
non-blank Sentry Key transponder when it should
see a blank, if it has already programmed eight (8)
valid Sentry Keys, or if the ignition switch is turned
to the Off position for more than about fifty seconds.
NOTE: If an attempt is made to start the vehicle
while in the Customer Learn mode (SKIS indicator
flashing), the SKIS will respond as though the vehicle
were being started with an invalid key. In other
words, the engine will stall after about two seconds
of operation. No faults will be set.
NOTE: Once a Sentry Key has been programmed as
a valid key to a vehicle, it cannot be programmed
as a valid key for use on any other vehicle.

got all that?
if confused, ask any ASE shop in USA for help
they CAN DO !
