Hi.
Check the hood ajar safety switch that is located under the hood at one side, near the front. The switch can be tested using a VOM set on impedance to check if it does close and open. The switch can also be tested jumping and opening its contacts.
Start opening the hood and locating the switch. See the diagram below:

Hi.
The hood ajar switch is not represented in service manual and parts manual shows the switch alone.The switch was not mounted in every Jeep Grand Cherokee from same year.The picture was taken from a general document about Chrysler hood switch.
You need to locate the switch under the hood. Here how the switch looks like (from Grand Cherokee parts manual):
Below two documents illustrating the two kinds of hood ajar detection system using in Grand Cherokee.
Hood ajar 1
Hood ajar 2
Here troubleshooting from technical documentation:
Open the hood.
With the DRBIIIt in Inputs/Outputs, read the HOOD AJAR SW state.
Does the DRBIIIt display CLOSED?
Yes ! Replace the Body Control Module.
Perform BODY VERIFICATION TEST - VER 1.
No ! Go To 2
2 Disconnect the Hood Ajar Switch harness connector.
Using a 12-volt Test Light connected to 12-volts, check the Ground circuit.
Does the test light illuminate?
Yes ! Go To 3
No ! Repair the ground circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
3 Disconnect the Hood Ajar Switch harness connector.
Connect a jumper wire between the Sense circuit and the Ground circuit.
With the DRBIIIt in Inputs/Outputs, read the HOOD AJAR SW state.
Does the DRBIIIt display CLOSED?
Yes ! Replace the Hood Ajar Switch,
Perform BODY VERIFICATION TEST - VER 1.
No ! Go To 4
4 Disconnect the Hood Ajar Switch harness connector.
Disconnect the BCM C1 harness connector.
Measure the resistance of the Sense circuit.
Is the resistance below 5.0 ohms?
Yes ! Replace the Body Control Module.
Perform BODY VERIFICATION TEST - VER 1.
No ! Repair the Hood Ajar Switch Sense circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
