What is the purpose of 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.
What are the fuses on a Jeep Grand Cherokee ASD relay?
NOTE: The above auto shut down (ASD) relay wiring diagram applies only to 1993, 1994, 1995 4.0L Jeep Grand Cherokee. The auto shut down (ASD) relay gets power from fuse #6 (15 Amp) and fuse #15 (30 Amp) of the Power Distribution Center (PDC).
What does it mean when the ASD relay shuts down?
ASD relay closes for 2 seconds, but you discover no 12vdc at coil + or injector 12vdc power is dead (during said 2 seconds), or (0v) cranking. – This means the ASD relay is bad. (bad contacts, replace it) ASD relay closes, but I have no spark to any cylinders. – So is bad Ignition coil, or crank /cam sensors or bad ignitor module.
What causes a jeep ASD relay to stop working?
Can be 50 causes, but in macro form is, bad engine bad spark plugs and wires, bad fueling, which can be flooding or lost fuel pressure (stavation) Stalls for bad engine are lost compression hot. Some engine can do that, even stuck open head valves now or only HOT. (and many more issues inside the actual engine)
How does the ASD work on a jeep?
The system and how it works. The ASD has engine startup logic that is unique to JEEPs. You must crank with in seconds or the key on, is ignored by many jeeps. You crank the engine, and the above list of logic checks, must not fail, during the start event or it cuts the ASD.

How to bypass ASD relay all that you know?
Go to the section that is spring. If your vehicle’s coil is not powered up as at that time, you then need to spring close the contact. Now you have to energize the coil of your vehicle so that you can have a flexible contact, which you are going to pull in.
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.
