Check the fuse box in the engine bay.

make sure batterys are ok - https://northcoastkeyless.com/2008-dodge-grand-caravan-keyless-entry-remote-fob-programming-instructions

Most likely a grounding wire is loose or a wire harness is touching something and grounding out.

Well in a short term, you have a short circuit somewhere. Here is a detailed toturial for you. Please rate this post, thank you.

Automatic Shutdown (ASD) sense - PCM Input

The ASD sense circuit informs the PCM when the ASD relay energizes. A 12 volt signal at this input indicated to the PCM that the ASD has been activated. This input is used only to sense that the ASD relay is energized.
When energized, the ASD relay supplies battery voltage to the fuel injectors, ignition coils, and the heating element in each oxygen sensor. If the PCM does not receive 12 volts from this input after grounding the ASD reley, it sets a Diagnostic Trouble Code (DTC).

Automatic Shutdown Relay - PCM Output

The PCM operates the Automatic Shutdown (ASD) relay and fuel pump relay through one ground path. The PCM operates them by switching the ground path for the solenoid side of the realys on and off. Both realys turn on and off at the same time.
The ASD relay connects battery voltage to the fuel injectors and ignition coil. The fuel pump relay connects battery voltage to the fuel pump.
A buss bar in the power distribution center (PDC) supplies voltage to the solenoid side and contact side of the relay. The ASD relay power circuit contains a 20 amp fuse between the buss bar in the PDC and teh relay. The fuse also protects the power circuit for the fuel pump relay and pump. The fuse is located in teh PDC.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and the camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position when the ignition switch is in teh Run position, it will de-energize teh ASD relay.
The ASD relay and fuel pump relay are located in the PDC near the battery. The inside top of the PCD cover has a label showing relay and fuse location.

ASD and Fuel Pump Relays

The following description of operation and tests apply only to the Automatic Shutdown (ASD) and fuel pump relays. The terminals on the bottom of each relay are numbered.

'------------------'
' __85 ___________'
' __87A '87 '30 ___' Sorry for the crudeness of this. This is supposed to
' __86 ___________' be the relay terminals!
'------------------'

OPERATION
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays, terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30. This is the On position. Terminal 87 supplies voltage to the rest of the curcuit.

TESTING
The following procedure applies to the ASD and fuel pump relays.
(1) Remove relay from connector before testing.
(2) With the relay removed from the vehicle, use an ohmmeter to check the resistance between terminals 85 and 86. The resistance shoud be 75±5 ohms.
(3) Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity between terminals 30 and 87A.
(4) Connect the ohmmeter between between terminals 87 and 30. The ohmmeter should not show continuity at this time.
(5) Connect one end of a jumper wire (16 guage or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12 volt power source.
(6) Connect on end of another jumper wire (16 guage or smaller) to the power side of the 12 volt power source. Do not attach the other end of the jumper wire to the relay at this time.

WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS TEST.

(7) Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The ohmmeter should now show continuity between relay terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and 30.
(8) Disconnect jumper wires.
(9) Replace the relay if it did not pass the continuity and resistance tests. If the relay passed the tests, is operates properly. Check the remainder of the ASD and fuel pump curcuits.

__________________________________________________ _______________

I know you said you replaced the relay, and this is a test procedure for the relay, but I have bought bad parts in the past. The description before the test procedure at least gives you an idea of what components are wired through and controlled by the relay. One of those may be faulty. Email me if you want or need wiring diagrams and I should be able to scan them and email them to you.

I hope this helps.

What is the torque specs for a thermostat for a 2011 Dodge charger

A few questions, what does aground have to do with this problem, next what is a "twic" and what is a "TIPM"?

You will need to scan the controller for codes. If there are none, the trans likely has no power to it. But, most likely is an internal problem such as worn clutches .

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U can also get free manuals

I strongly suggest checking your vehicle owners manual.
It provides a map of your fuse location and identifies each fuse .

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help thanks

You have a bad earth, check under the footwell panel driver side deep high there is 5 to 6 wires normally fasten with a 10 mm bolt it came loose so u need to fasten it, if not the main plug behind the cluster panel ground terminal shall be burned loose or dirty contact on it only those two

some van don t have a ground wire. hook up to trailer put jumper cables to frame of trailer and van if works install a ground wire plug

Check the hose connection to the heat exchange. If there is a leak there, you will smell it inside the vehicle and you may not see a leak on the ground as it evaporates when the car is running.

If the fuel pump and injectors check out OK, then this is likely an intermittent throttle position sensor. Sensor thinks the engine
Is flooded and shuts off the injectors.
This may never set an engine code.

What is dnl if you wright with out abbreviation like in the army ,I will help you,all the best.

Please use the full name of the relay and not the acronym

You could also make this from an automotive grade silencer pad.

Under the hood, locate the throttle control (near or under the air filter housing, you can have someone step on the gas back and forth to see it move and identify it). Once you find it, you can manually move it back and forth (do all this with the engine NOT running, in the off mode). The idle can be adjusted usually with a screwdriver but you also might have a problem with the cable itself sticking. Run some oil or other suitable lubricator (like WD-40) back and forth, moving the cable to get it loose. (there's a little screw to loosen or tighten the idle, it basically opens or closes the throttle more)

The best solution you'll get from books at www.reliable-store.com These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicle- cars, atv, trucks. forklifts, boats, excavators etc.

could be a weak radiator cap allow pressure to escape and creating a vibration in the radiator When an engine is turned off, the hot cylinders still put heat into the coolant and as it is not being circulated, the system pressure rises and if the cap is not in good condition it will vibrate as it looses that extra pressure check for cooling fans still running or fuel pump not still operating
