The autoshut down relay powers up a lot of stuff, injectors, coil, alternator. The PCM turns it on only after it gets a signal from the crank sensor. It may be fed by a fuse link not a fuse, not sure. What kind of problem are you having?

1998 Jeep Laredo continuous clicking sound passenger side under dash it runs battery down ignition is off continuous clicking please help thank you


A number of people in the link report the same problem on the Jeep Forum and there are a number of fixes.

I also found this for you.

The problem seems to be a short in one of the rear dome lights, which seems to be affecting two fuse circuits. The temporary solution was to remove one fuse and replace another (blown), and remove the bulb from the bad dome light. I had to remove "fuze#5-15 amps-Interior Lighting", this stopped the clicking noise, I replaced blown fuze#8-15 amp-Overhead Console, keyless Entry ..." This fuse also seems to effect the alarm system (contrary to the documentation), and I think that was what was killing the engine. The problem existed before fuse#8 blew. Removing fuse#5 may have solved the problem, but the other fuse blew while I was testing the dome lights, and the jeep will not start without it.

Found lots of wires bare or broken in all the door wiring harnesses ( in rubber boot that goes to the door)I first checked both fuse 5 and 8 but both o.k. After fixing the broken wires found fuse 8 had blown. Replaced that and all is well again. Thanks for the advise got me looking in the right direction.

. Fuse box located in passenger side door jam...check #8 fuse if its not blown check others...if it is blown, check your radio, and interior lights for good ground

My 91 jeep wrangler 4.0 will shut down all power at all speeds from idle to driving on the interstate. I jumped out the auto shutdown relay and it works fine but i cannot find the auto shutdown switch to...


There is no switch. The relay gets a signal from the computer. If there is no signal from the crank position sensor the computer will not close the relay. If it runs with the relay bypassed, chances are good that the relay itself is bad.

Auto shutdown security code removall


The 93 Grand Cherokee does not have an auto shutdown security code. To shut down the factory security, you have to unlock the rear tailgate lock cylinder with your key. If the jeep shuts down for any other reason, there is something else wrong with it.

Replaced timing belt engine will not start


check for spark at the sparkplugs, and listen to hear the fuel pump going when key is turned on. if no pump noise and no spark it can be the auto shutdown relay located on the drivers side fender behind battery. the auto shut down shuts off power to the ignition and fuel pump if the timing belt snaps. ,,,, if you have spark and fuel pump works then check firing order on plug wires , if they are in right place then check timing , if timing belt was replaced without lining up the timing marks it wont run

What does the auto shut off fuse do? 92 Jeep Wrangler is having start up problems.


The auto shutdown relay in your vehicle is controlled by the computer. If the computer does not see a signal from the crank or cam sensor, it will turn off power to the relay which in turn shuts off power to the fuel and ignition system. Unlike those in many passenger vehicles, it's not connected to an impact sensor. (as jeeps are off road vehicles as well as being transportation, if they had an impact sensor, they would be prone to shutdown when traveling over rough off road terrain)
The fuses to the relay are affected by shorting or overload of any components they serve, or by a problem with the relay itself.

Where is the fuel shut off switch and how do I reset it


Jeep doesn't use fuel shut off switches. The fuel system is computer controlled with relays.

94 Jeep Grand Cherokee will not start


Sounds like the inline fuse popped. It is located in the wire that comes from the alternator to the battery. The alternator is sending out the juice, but it can't make it to the battery. I sincerely hope that this gets you on the road again. Best wishes and God Bless.

Jeep keeps blowing auto shutdown fuse


Yes I had the same problem. The wires that plug into the sensor at the catatytic converter were rubbing against the drive shaft untill they finally wore through causing the short against drive shaft. repaired wires and it fixed everything
