Thread: EAS Workaround.... bad idea?

Why not just fix the problem "A happy wife is a peaceful life"

Otherwise, tap into the wires below the relay box and run a switch into the cabin so it can be done with relay in place, sitting in vehicle...

And no, its not good to bypass and use the switch all the time - so make it momentary so when you let it go, it cuts off.

How come it wont run the compressor? does it happily run the compressor once pressure is up after you have jumpered it or does it simply nerever run the compressor?

Eas ecu? driver pack on the valve block? Faulty temp sensor on pump?

Do you have a obd-serial cable and eas software to check for codes?

Its not jusst a bad relay is it?

Idealy all p38's running air suspension should have the manual air recovery system fitted.
If you have it with taps on the lines, you can just turn off the taps, pump up the 4 valves to around 60lbs, pull the plug on the pump inside the box and off you go.
My son has been doing this for a while and it works fine off road with a bit more pressure, but it must be even from side to side.
There doesnt seem to be much loss of articulation.

Nah it's "seemingly" completely random. Sometimes once pressure is up it will work fine. Sometimes even when down entire system might run perfectly for a day or two, then it's back to square one. Counts out faulty relay. An "expert" here in Perth tried to convince me it was the temp sensor on the pump so I would but one of his reconditioned pumps, but grounding the temp sensor at the pump doesn't get it to run either... Have had it checked with obd serial cable and software but didn't come up with anything definitive... Could be valve block or ecu...don't know how to check that though...

Thanks for the tip. Yep it's something I'm definitely I'm looking into...

Good point on using a switch that 'let's go'. Can take a few minutes to pump up though, I think my finger might get sore

What's the advantage to tapping into the wires and leaving the relay in place?

.

You are a patient man if you have let this go on for 6 months.
What have you tested? Its easy enough to test the pump ( which seems to work) Thermal cut-out ,pressure switch and swap over one of the other relays.
I have had issues before which was simply a bad connection on the compressor plug.
I have a good spare compressor here (not for sale) if you wanted to to come over and do a quick swap to test it if you think thats the problem. I have also bypassed the cutout on the compressor before if thats your problem its an easy solder job. I have the eas software and lead here if you dont have them.

Patient? yes. Bloody frustrated? yes, yes.

Thats a great offer and I think I might take you up on it if its not too much of an imposition...
