How To Check ASD Relay for Power Jeep TJ

I should have actually mentioned this in the video but when you first turn the ignition on the Asd will energize for a few seconds. it needs to see a crank signal for it to work properly. so in other words if your cranking the engine over and the ASD isn't powering up then something is wrong. start looking for a blown fuse or other electrical issue.

I'm having this issue. Thanks for the instructions. Was about to buy a crank sensor and you saved me 100 bucks so far. Onto the o2 sensor

The negative wire from relay to PCM works fine, thanks for your wonderful video

Wow, thank you! Wish i had youtube when i was younger.

im working on a 99 laredo and found this shortly after i tracked it down to my asd buzzing. gonna check those fuses and see if thats whats up! thank you so much for the informative video!

[blainflake]

Awesome video man! Dealing with a asd no activation issue right now. Hate wiring issues and am like a small child when fooling with a meter. I rely on these types of videos for direction. Thanks again for the info.

[dennisbell]

Thanks I got it, all working, got someone to crank enjin and all the fuses and relays work, thanks so much

My oxygen sensor was shorting to the axle. The ASD fuse was breaking. Thanks for the help!

I think you're smart to go through every step on this know so many people want and will do this swap.

Good evening sir I have been on almost a 3 week long extravaganza on Trying to resolve a asd/pcm issue in my 06 lj. I’ve owned 10’s of tj’s as well as xj’s Cj’s and even Willy’s, as a life long keeper I’m mind blowing from all of my electronic diagnostics. I know this is a long shot but is there any other platform I can shoot you a message on and possibly have you give me a call just to have a few mins of your time. I’m well mechanically backed and in electronics and i’m butting my head after 3 weeks. Literally pulled jeep out of garage and just flopped a few relays just to check ac clutch relay function and just from simply flopping around I ended with a no crank no start no pcm com and asd and related relays are chattering. Great voltage. Full pin out and ground check. Obd2 test and pin out, every sensor 5v to everything and tested all asd related sensors all check good, again at a loss here would be great to get in touch with you just need a good secure way to send you my contact info thank you sir

Jerry really liking this video series. Lots of good info and how to's. Anyone doing this swap should watch this.

Great Video. It might help me figure out a 2010 JK Problem.

Awesome video you covered it all now I can tell if there is a short.got to do this myself and short on money

[coachgeo]

Do all the relays slots in the PDC (Power Distribution Center) work in similar way such as ASD you showed in video when it comes too.... which pin is constant power... which one would relay give power only at key of "start/ignition", which one is run power (key switch relay to give it constant 12v) etc...

[SWTWHITEGSR]

Excellent video ! Question if the accessory wire on asd is showing voltage but on crank voltage goes away! Would that be normal?

[dwainehiggins]

Thanks for your video. I have a question that I hope you would consider answering. I have replaced just about everything on my Jeep. ECU, plugs, distributor, coil, sensors, etc. My Jeep runs for 2 seconds then shuts off. Something is telling the ECU to shutdown the ASD. Any thoughts? 98 Wrangler 4.0.

[DivingMechanic]

Nice. Can you tell me if there is a easy wat to determine if the 2002 tj x I just got has SKIM? only has a aftermarket key.

[spelunkerd]

Ha ha ha, it's my old friend from BullSh*tKorner, now with a more politically appropriate channel name. This one came up in my feed, nice summary of the ASD relay. Glad I found you, again!

[Tony_ASA]

What happened with the head gasket leak?

[ddesilva]

Tidy looking work coming together in that engine bay!

Quick question BSK, can a jeep tj run without the cat/02 sensor?
I removed the cat and 02 sensor on my tj because there was a hole on the exhaust pipe right before the cat causing a leak. I disconnected the o2 sensor plug and left the wire hanging on the jeep and the sensor itself I removed with the cat. It started up (very loud of course) and after driving around the corner it shut off and wouldn't turn on. I checked the fuses and the ASD fuse was blown. Did this possibly happen because the hanging wire shorted out underneath? If I tuck the 02 sensor wire out of the way, should the jeep be able to run with no cat or 02 sensor installed? this is just temporary until the exhaust pipe is fixed.

THANKS BSK
