How do you test a Jeep ASD relay?
(ASD) Relay Testing, With An Ohmmeter With the relay removed from the vehicle, use an ohmmeter to check the resistance between, terminals 85 and 86. The resistance should be, 75 ohms 5 ohms. Connect the ohmmeter between, terminals 30 and 87A. The ohmmeter should show continuity between, terminals 30 and 87A.
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)
Why do I get a no start Jeep?
If so, the PCM provides ground to the auto shutdown relay (ASD), also called the MAIN relay which then operates to provide power to the totally integrated power module (TIPM) which provides power to the fuel injectors and ignition coils. If there’s an issue with the ASD relay or the wiring to the ASD relay, you’ll get a no start Jeep condtion.
How does the auto shutdown relay work on a jeep?
When you turn the key, the PCM/BCM anti-theft system determines whether you’re using the proper key. If so, the PCM provides ground to the auto shutdown relay (ASD), also called the MAIN relay which then operates to provide power to the totally integrated power module (TIPM) which provides power to the fuel injectors and ignition coils.
Where is the ground on a jeep starter?
If you see battery voltage, check for ground on pin 85 in the relay socket. The PCM provides ground to the starter relay control coil AFTER it determines the anti-theft system has passed the authentication test.
