What is ASD relay Dodge Caravan?
The ASD (Automatic Shutdown) relay in a Dodge Caravan is a crucial component that plays a vital role in the vehicle's electrical system. This relay is responsible for controlling the fuel pump and other critical functions, ensuring the safe and reliable operation of the minivan.
What is the ASD Relay?
The ASD relay is a small, electronic component that acts as a switch, controlling the flow of electricity to various systems in the Dodge Caravan. It is typically located in the fuse box or under the hood of the vehicle. The ASD relay is designed to automatically shut off the fuel pump and other electrical components in the event of a collision or other emergency situation, preventing potential fire hazards and further damage to the vehicle.
How Does the ASD Relay Work?
The ASD relay is connected to the vehicle's ignition system and is activated when the engine is running. When the ignition is turned on, the relay allows electricity to flow to the fuel pump and other components, enabling the vehicle to start and operate normally. However, if the ASD relay detects a problem, such as a collision or a sudden loss of power, it will immediately cut off the power supply to the fuel pump and other critical systems, preventing the risk of fire or further damage.
Symptoms of a Failing ASD Relay
If the ASD relay in your Dodge Caravan is malfunctioning, you may experience the following symptoms:
- Engine won't start: If the ASD relay is not functioning properly, it may prevent the fuel pump from receiving power, making it impossible to start the engine.
- Intermittent stalling: A faulty ASD relay can cause the engine to stall unexpectedly while driving, as the relay may intermittently cut off power to the fuel pump.
- Electrical issues: A malfunctioning ASD relay can also cause other electrical problems in the vehicle, such as flickering lights or issues with other components.
If you experience any of these symptoms, it's essential to have your Dodge Caravan's ASD relay inspected and replaced if necessary to ensure the safe and reliable operation of your vehicle.

Where is the ASD relay located?
If this part fails, the engine can stall, fail to crank, or lag while accelerating. The ASD relay is in the junction box under the hood. In some models, this part is already integrated into the TIPM.
What does the ASD relay do?
"Auto Shutdown Relay". It powers up the fuel pump and fuel injection components indirectly. When you turn the key on, the PCM energizes the ASD briefly to provide a fuel system prime. After that it turns off until the PCM has a good crank signal.

How do I know if my relay is bad?
Listen for an audible click as the electromagnetic coil activates and the internal switch closes. Switch your multimeter to continuity mode, listen for the audible beep, and test for continuity between the switch pins. If there's no beep, it means the switch pins are stuck open and your relay is faulty.
