P1389 : No ASD Relay Output Voltage At PCM : An open condition detected in the ASD relay output circuit

That would make sense, the ASD relay supplies power to the fuel pump, injectors, coils etc So if the relay control wire was open you'd never see power at these components

The Powertrain Control Module (PCM) operates the Auto Shutdown (ASD) relay by switching the ground path on and off

after messing with it for a few hours and not finding the problem i was going to have it towed home I have no ground to asd relay truck will not start

CHEAP FIX that costed me a small fortune!!! ASD relay in the engine compartment fuse box

3rd Gen Ram Tech - ASD relay not getting ground from pcm - i have a 2004 dodge ram quad cab 5

took it on a 75 mile trip parked it for a few minutes and went to start it back up, had full power (windows, radio, lights etc) but the gauges wouldnt move when key was turned I have 2004 dodge 1500 with 5

on your web site it shows this diagram with #85 going to ground

As you see later this code doesn't look only at the K51 circuit but seemingly the ASD circuit as a whole

Sep 12, 2011 · The PCM switches the ASD relay off depending on 2 things: 1) with the ignition switch in on, but the engine not running for more than 2 seconds

When Monitored: With ignition key on, battery voltage above 10

If the 2 lines are depicted as meeting at the circle or dot, the relay is a normally closed (NC) relay

Very often a blown ASD/FP fuse is caused by a worn pump thats pulling too many amps

Code 42* ASD relay control circuit An open or shorted condition detected in the auto shut down relay circuit

There is no continuity between If the controller does not receive a distributor signal when the ignition switch is in the RUN position it will de-energize (remove ground) the ASD relay

If you have less than battery voltage to your pcm and ecm then you have corrosion or a break in the main power wire

So in your case, if you have no PCM, and  23 Jul 2012 You need to measure from that wire to a good ground (like the engine block)

Listed below is the vehicle specific wiring diagram for your car alarm, remote starter or keyless entry installation into your 2002-2003 Jeep Liberty

The Diagnostic Trouble Code (DTC) will set in the Powertrain Control Module memory when PCM does not sense voltage when ASD relay is energized

The ASD-120 has no line cord or master breaker, and is designed to be permanently wired to a single phase 120/240V source with 60 amps per side capacity, or to a three phase 120V source with at least 40 amps per phase capacity

P1390 : Timing Belt Skipped 1 Tooth or More Relays are available at Mouser Electronics from industry leading manufacturers

Aug 06, 2019 · Confirm the integrity of the relay load connections

The PCM monitors distributor signal to determine engine speed and compute injector synchronization

(it sees, and knows spark is bad here) (It can’t see the secondary High Voltage side, just the primary) Maybe but you need to use a scan tool to check for codes and then to command the asd relay on and see if you get ground to the relay

Mitchell1(R) obtains wiring diagrams and technical service bulletins, containing wiring diagram changes, from the domestic and import manufacturers

changed fuse box and pcm with ones from salvage yard still wound not start

The Integrated Power Module is located in the engine compartment near the air cleaner assembly

For longer range UAV operations Iran has learned how to use some UAVs as airborne relays

As with most electrical components, the (ASD) relay is subject to the normal wear and tear associated with normal service

I was hoping someone had an answer to the function of the ASD relay

took it on a 75 mile trip parked it for a few minutes and went to start it back up, had full power (windows, radio, lights etc) but the gauges wouldnt move when key was turned to the on position, fuel pump wouldnt turn on, shifter indicator wasnt present around the gears

May 13, 2009 · 7: No speed signal from Any sensor (L6,L6/1,L6/2), missing ground 8: ASD valve(Y38) or Stop Lamp Switch (S9/1)" Fix your ASD sytem accordingly (Iam a funny man ) Apr 21, 2017 · Read again, I said cam and crank SIGNALS

sorry i dont know where they are located on a van but i believe there is another post with similar problem

I'm reviewing your question and I will be posting your reply ASAP
