Question edited for clarity.
Question moved to model category.

The security alarm and engine immobilizer are functions of the Body Control Module (BCM) and the ECM. You can't just pull fuses. When the battery goes completely flat, or is disconnected, you just need to reset the Security System which is done via the Remote Fob.

its a vacuum hose issue. mine did the same thing and all it was is the vacuum hose on right side of the engine came loose. check all your 1/4" diam vacuum hoses under your hood

First I suggest to check fuses and wires.

Also check brake switch adjustment, it is the interrupter.

Try inspecting the fuse. If it's blown, replace it. It also may be a short in the wiring. If this was at all helpful, please rate. Thanks for asking.

Could be several things,

1. thermostat
2. water pump
3. fan motor is bad (is the fan running when at temp?)
4. fan motor relay

Is it running hot all the time or just when setting idle?

try the brake switch located behind the brake pedal....had similar problem and this fixed it

Ok, the '03 Jeep Grand Cherokee uses a small vacuum line to control the servos. Since your light comes on, it's obviously getting power. 9 out of 10 times it's the vacuum hose.
Pop the hood and look on the passenger side towards the back for the engine coolant reservoir. It's most likely underneath it so you may have to remove the res. Check the vacuum hose and all vac. connections then check the electrical connections. If that's not the problem, check the cruise control connection to the throttle linkage.
If that still doesn't do it, you may need use scan tools and diagnostic procedures that are out of the scope of home mechanics.
Wish ya luck!
