What is the ASD relay?
What is the ASD relay?
One of these components is the automatic shutdown relay, commonly referred to as the ASD relay. The ASD relay is responsible for supplying switched 12-volt power to the vehicle’s injectors and ignition coils, allowing them to provide fuel and produce spark.
Where is the ASD relay on a Dodge truck?
kudran, yes it can. The ASD relay is located in the Integrated Power Module (IPM), in the engine compartment. Refer to label on PDC cover for relay location. To test the relay see if this helps. When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
Can a fuel pump relay pass the ASD test?
If the relay passed the tests, it operates properly. Check the remainder of the ASD and fuel pump relay circuits. You may be going down a very deep rabbit hole. Remember that Chrysler had incredible trouble, including multiple lawsuits and recall’s based on TIPM issues.
Where does terminal 87 connect to the fuel pump 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 circuit. The following procedure applies to the ASD and fuel pump relays.
What causes the ASD relay to go down?
That led to the need for a new alternator (low voltage when running). Then when truck was left alone for awhile, battery would go to 0. Found that fuel and ASD relays would chatter intermittently, running battery down.

Can a fuel pump be connected to a fuel relay?
To work properly, two conditions must be met: The fuel pump must be connected directly to the fuel pump fuse (fuel pump relay must come before the fuse slot). The easiest way to confirm this is to verify that no voltage exists on the fuel pump fuse when your vehicle is turned off.
What are the symptoms of a bad ASD relay?
One of the most common symptoms of a bad (ASD) relay is an engine that will start. But, Stalls almost immediately, or at random times. The (ASD) relay supplies power to the vehicle’s ignition coils and fuel injectors.
