Asd relay has no power to the pcm and fuse panel inside has only half power run jumper wire to dead fuses and dash lights up and pcm powers up and jeep will start and run till jumper wire is removed

According to a post on Fixya, if the ASD relay has no power to the PCM and fuse panel, you can try the following steps:

Force +12 volts onto the relevant fuse by jumpering pins 30 and 87 in the ASD relay socket.
Pull out the ASD relay and use a 12 volt test light to interrogate the relay socket.
Replace the ASD relay connector if it is damaged, loose or shorted.
Check if the ASD relay output circuit is open between the relay and PCM.
Check if the ASD relay power circuit is open.
Replace the ASD relay if it is damaged or has failed.
Check if the PCM has failed.
If you're not comfortable performing these steps yourself, it's best to take your car to a qualified mechanic who can diagnose and fix the issue.

no engine TOLD AT ALL OF 3, (USA?)
fast answer is ASD relay sees hard errors and did that on purpose
not scanning the PCm cranked is why you fail to see why ASD dropped out. (for sure)
or not testing huge fuses too. F1 must not blown


sure , the cars schematics make all that clear as day.

https://eautorepair.net/Marketing/Default.asp

that means ,. mostly , the main fuse blew that runs those 5 fuses
but let me read the schematics to you.
well fuse 1 runs that set, 60amp huge fuse blown.
I assume other fuses have power, did they:? and battery too?
next time measure all fuses, for sure HUGE fuses TOO.


fuse 10 is crank only fuse, so not cranking fuse is dead.
15/16 is wired directly to the battery, so looks like wiring bad to 15
f12 is a not used fuse or listed spare.
fuse 8 kills RUN on IGN switch.

fuse 14 runs the cluster, but F1 runs F14 and more,not in your list
fuse 10 is super important to EFI to PCM but is only start /crank signal to PCM.
Fuse 8 way more important to EFI is RUN /start power to PCM
huge fuse 2 and 4 good that feeds fuesible link 14
fuse 6 is fuel pump and its relay power
F12 is not used
keep mind, 4 engines here and not told. so fuses usage varies and for sure IMMO key , enigine IMMOblizer not happy. and present


this car has RUN ASD relay R1 ,drops out of PCM sees spark dead
is spark dead? or IMMO key failed.
is IMMO lamp unhappy, showing KEY BAD etc?

F20 and F29 power To PCM
now the ASD auto shut down relay if disabled (reasons)
F14,15,and 16 will be dead. by design (runs off ASD)
F11 kills power to said relay ASD
and that kills dead all SPARk and fuel in seconds.
the PCM runs the ASD relay and is programmed to shut ASD down
even in 1second (runs for 1sec is clue 1) a few seconds max.

if spark tests fails hard. (the a chicken and egg deal)
as you crank the PCM checks spark is good (no spark ICM errors or CMP or CKP hard errors), and if YES it cuts all spark and injectins
to prevent CRAsh AND BURN AS SEEN ON TV. AND BY LAW.

So on any car like this. 2005 up for sure x10
we scan the PCM while cranking
and OMG CKP or CMP are dead.
or gross spark ICM errors (COP coil drivers , show many are dead?)


ASD is tricky I use timing light cranked and see spark go GOOD and fails in 3 seconds I bet ASD did that.
but also spark can be 100% dead, (like CMP or CKP is dead)
the PCM does not know those are dead until cranked
the see them dead and drops ASD fast to avoid fuel fires.
that is how it works.
or IMMO lamp flashes (HEY I am killing the engine dead now)

DODGE RAM. (per OBD2 is OBD1 dodge unique) USA LAWS.
all plugs dead, we check them all. not just one.
USA spec car? v10.
learn that all ECU/PCM cuts fuel if the ECU detects lost spark
it cuts fuel so spark is first, on all spark plugs
are the plugs over 100k miles old?
ASD WORKS LIKE THIS IF ECU SEES SPARK DEAD ECU DISABLES THE ASD, THIS PREVENTS CRASH AND BURN AS SEEN ON TV.
ALL FUSES GOOD RIGHT> WE TEST THEM.

KEY ON CEL MUST GLOW, THIS KEY ON EVENT IS THE LAMP TEST. IT MUST GLOW ONCE AND CAN GO OUT. AFTER.
IF NOT THE PCM LOST POWER, CALLED BLOWN FUSE.

THE CURE IS BASED Purely off ASD dead.
on all cars Chrysler. even jeeps,
The PCM seens any thing dangerous ASD drops
or even fails top close;. once

my guess is you do not know how to test fuses?????
there are 3 tests, in increased value.
1; gander at it ,looks blown it is. but looking good can be bad.
2: Ohms test can lie if hair line cracks here. but is great test.
3:live test, 12vdc, key on , both sides of fuse 12vdc is good
12 vdc in, and 0v out is a bad fuse (or bad fuse and shorted load)
nothing on earth bets a live test, pass /fail .

learn now the CEL lamp works key on (self test)
learn too how to do THE SM book ODB1 CEL code flash test.'called then Diagnostic jumper.

in 1995 USA this ECU has DLC connector, that has jumper pair of pins called Diagnostic, test.

quote

When the CHECK ENGINE light comes on and stays on (after start-up), this indicates that a code (or codes) has been stored in memory. To retrieve this information for purposes of troubleshooting, cycle the ignition switch ON- OFF- ON- OFF- ON within five seconds. The check engine lamp will then flash the DTC(s). Each code, if there is more than one, will be preceded by a four second pause, to distinguish it from the previous code. An example of a DTC would be as follows:

• Lamp on for two seconds, then turns off.
• Lamp flashes four times, then pauses, then flashes one time.
• Lamp pauses four seconds, then flashes four times
• Lamp flashes seven times.
• code 47, per SM.

codes 43 is ASD relay is dead. bad
code 43 is any bad spark coil , kills ASD dead.
53 dead ECU
54 cam sensor dead., code 11 is crank sensor dead.
63 dead ECU
55 = end of report

no symptoms told is engine dead, or is DTC for O2 set.?
no clues told to put helpers on target.

are you asking which fuse blew or why it did.?
a fuse has 2 end both ends are 12vdc key on
if one end is now 12v but near 0v the fuse is BLOWN
no better test exits. doing that with a DMM. (a live test)
well the fuse is blown and 02 love to short the 2 heater pins
or wires at it burned and shorting, loves to....
no engine told so exact answers are not possible
the service manuals are by country ,year, make,model, engine and transmission, if driveline problems and is.
gen 1 is DODGE:
3.9 L (238 cu in) Magnum V6
4.7 L (287 cu in) Power Tech V8
5.2 L (318 cu in) Magnum V8
5.9 L (360 cu in) Magnum V8V6

USA drawings, show.
OXY fuse is
Fuse A1 , 10 amps. a1 is hot if ASD is not dead keyon.
same fuse A2 if A1 is hot, and A2 is dead, the fuse A1/2 is blown
all 4 OXY sensors run off that one FUSE
now lets talk why pin A1 WOULD BE DEAD
WELL THE ASD IS DEAD. IS WAY .
ASD GOES DEAD FOR ONE PRIME REASON, SPARK IS DEAD.
THIS MAGIC LOGIC IN THE PCM PREVENTS CRASH AND BURN.
3 CAUSES ARE.
1: PCM SEES ANY COIL SPARK FAIL (DETECTED)
2: PCM SEES CMP DEAD.
3:PCM SEES CKP DEAD.
OR PCM FUSES BLOW, TO IT. SURE
. PCM RUNS ASD ALL BY ITSELF AND ITS RULES.
Why not start problem by telling it first.
engine dead, cranks ok.?
or runs for 1 to2 second and ASD drops and sure stalls.

won't start means what,
will not crank./?if silent is the starter relay not clicking (now)
or cranks fast and will not start or does for 3 seconds and stalls?

in the fuse relay box , mostly in the engine bay
lost the operators guide? out of glove box.
will not crank at all (silent)
or cranks fast but will not start
or starts and stalls fast or slow. ????
will not run and stay running
yes engines can do that ,.

The ASD is the controlled by the PCM.
if the PCM sees danger it drops the relay
one danger is the PCM sees spark bad. and cuts fuel dead by dropping the ASD., dead on PURPOSE
for sure prevents FUEL fire, CRASH AND BURN as seen on TV
USA car, not told
USA A scan tool so it can tell you what is wrong in 1 minute flat.
buy one, rent or barrow one.?
step 1 is check all fuses. then scan it.
My first ASD was in my 88 jeep.
they could call it the ESD, emergency shut down relay or panic relay.
PCM logic controls it ONLY IT. !!!!!
NO anti-theft option on car or its LAMP angry.
right, ?
ASD causes of what?
11 pages on ASD
fuse 6 or 9 blown. bingo. ASD dead as a door nail. JB and Power center.
ASD dead injector power will be DEAD fully
ASD DEAD , ALL SPARK COILS HAVE NO POWER NOW



the asd coil pin low side is grounded (a transistor)
below see the PCM pin that does that.
and as I told you the PCM will kill the ASD on purpose for
at least 2 reasons (IMMO not happy) or senses spark dead
or he pre_cursors of spark dead, CMP or CKP (Or out of sync)
or the spark coil primaries dead.
but you failed to use a scan tool and work blind.



to use the scan tool do this

1. connect to OBD2 port 16pin at knees.
2. tool on.
3. key on, crank until it stalls. crank for 10 seconds.
4. release the key do not turn it off
5. let the scan too scan add see P03xx errors. DTC.
6. now key off. only NOW.

The next step is to pull the ASD relay and the fuel pump relay one at a time to see if the draw goes away. The ASD and fuel pump relays should only be energized with the key on for a couple of seconds, anytime the engine is cranking, or anytime the engine is running. If the draw continues than you may have a PCM issue as the only wire that does not go through the two relays but is fused bu the same fuse goes to a battery positive input to the PCM.

a word of caution. It can take a half hour or more for modules to power down. if you are not waiting at least a half hour before checking your final amp draw you may be seeing a false reading.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Maybe I can give a little help. Do you have the 4.0 liter straight six engine? This should apply as well if you have the V8 engine.

:...no check engine light...:With key on, does the light turn on? If not, it may not be getting power. Have to check that first, check all fuses in the under hood relay/fuse block. The check engine light should turn on with key in on position, just as an alert that the PCM is powered, and ready to work.

"...no electric to coil..." With key on, the dark green/black wire to the coil should have battery voltage. In that fuse/relay block will be a relay called an Automatic Shut Down relay (ASD relay). When the PCM turns this relay on, power is sent to the ignition coil on the green/black wire. The power feed for the ASD relay is fuse 2, a 20 amp fuse in the Power Distribution Center -the fuse/relay block under the hood.

So you have a couple of things to check: Make sure the PCM is powered. If it is, hold your finger lightly on the ASD relay while someone turns the key to on. You should feel it click on. If it does, but no power at the coil, check if fuse 2 is sending power to the relay, and check the green/black wire from relay to coil. If no relay action, possibly a bad relay, or the PCM is not turning the relay on.
Good luck. Let me know what you find.

Rewrite.

Well in a short term, you have a short circuit somewhere. Here is a detailed toturial for you. Please rate this post, thank you.

Automatic Shutdown (ASD) sense - PCM Input

The ASD sense circuit informs the PCM when the ASD relay energizes. A 12 volt signal at this input indicated to the PCM that the ASD has been activated. This input is used only to sense that the ASD relay is energized.
When energized, the ASD relay supplies battery voltage to the fuel injectors, ignition coils, and the heating element in each oxygen sensor. If the PCM does not receive 12 volts from this input after grounding the ASD reley, it sets a Diagnostic Trouble Code (DTC).

Automatic Shutdown Relay - PCM Output

The PCM operates the Automatic Shutdown (ASD) relay and fuel pump relay through one ground path. The PCM operates them by switching the ground path for the solenoid side of the realys on and off. Both realys turn on and off at the same time.
The ASD relay connects battery voltage to the fuel injectors and ignition coil. The fuel pump relay connects battery voltage to the fuel pump.
A buss bar in the power distribution center (PDC) supplies voltage to the solenoid side and contact side of the relay. The ASD relay power circuit contains a 20 amp fuse between the buss bar in the PDC and teh relay. The fuse also protects the power circuit for the fuel pump relay and pump. The fuse is located in teh PDC.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and the camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position when the ignition switch is in teh Run position, it will de-energize teh ASD relay.
The ASD relay and fuel pump relay are located in the PDC near the battery. The inside top of the PCD cover has a label showing relay and fuse location.

ASD and Fuel Pump Relays

The following description of operation and tests apply only to the Automatic Shutdown (ASD) and fuel pump relays. The terminals on the bottom of each relay are numbered.

'------------------'
' __85 ___________'
' __87A '87 '30 ___' Sorry for the crudeness of this. This is supposed to
' __86 ___________' be the relay terminals!
'------------------'

OPERATION
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays, terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the 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 curcuit.

TESTING
The following procedure applies to the ASD and fuel pump relays.
(1) Remove relay from connector before testing.
(2) With the relay removed from the vehicle, use an ohmmeter to check the resistance between terminals 85 and 86. The resistance shoud be 75±5 ohms.
(3) Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity between terminals 30 and 87A.
(4) Connect the ohmmeter between between terminals 87 and 30. The ohmmeter should not show continuity at this time.
(5) Connect one end of a jumper wire (16 guage or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12 volt power source.
(6) Connect on end of another jumper wire (16 guage or smaller) to the power side of the 12 volt power source. Do not attach the other end of the jumper wire to the relay at this time.

WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS TEST.

(7) Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The ohmmeter should now show continuity between relay terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and 30.
(8) Disconnect jumper wires.
(9) Replace the relay if it did not pass the continuity and resistance tests. If the relay passed the tests, is operates properly. Check the remainder of the ASD and fuel pump curcuits.

__________________________________________________ _______________

I know you said you replaced the relay, and this is a test procedure for the relay, but I have bought bad parts in the past. The description before the test procedure at least gives you an idea of what components are wired through and controlled by the relay. One of those may be faulty. Email me if you want or need wiring diagrams and I should be able to scan them and email them to you.

I hope this helps.
