Thread: 1993 EAS fuse??

Under driver's seat, outer trim panel.

BIG fuse... you can't miss it.

But, how do you know the EAS computer is not having internal conniptions... ?

- Dropping to lowest height is a give-away that it fears a fatal fault... you need an EAS Kicker to fault-find.

well, its been working fine,
check the easy things first, and i cant hear the compressor going anymore

Don't quote me... but from Ancient Memories... there's a normal sized fuse in with the rest of the car's fuses. This powers the EAS - ECU.

IF the main and other fuses are OK, then the reason the pump is stopped is.... it ain't being told to GO.

Check with RAVE ( CD is available here on Dave's Shop) for the wiring of the pump, so that you can 'manually' power it up.
They did have a problem around the brush-holder assembly and a modification to this bit is usually done at overhaul time.

IF your pump has never been re-furbished, then.... . . .

By all means do the Simple Stuff first... but bottom-line is.... "Is the pump being commanded to operate ?"

G`day ,

The other is B4 but the ignition relay also uses it so if it`s running it`s probably not .

The main maxi fuse is under the drive seat .

I`d have to find it but somewhere i have the ecu pin numbers and which ones to bridge to run the pump , fill each bag ETC .

If you try to hard wire the pump to run it be aware you have to pick the right 2 wires because if you power the 3rd wrong one the overload no longer works nor will the pump without earthing the 3rd wire but as said no overload , i forget the wire colours .

Let me know if you want the ecu pins and ask your dad if it has 3 solid lights on the switches .

thanks for the replies, ive only, (my dad too) had RRC's with springs....
The guy he bought it off said all the air suspension had been refurbished & has worked perfect since he bought it 6/7 months ago

G`day ,

can`t tell you what`s wrong but if the pump works and it will hold air , we can get it off the bump stops by using the ecu plug pins and set it to a single height so he can use it or drive it to some software .

ok, thanks, might take me a while to get to look at it.
maybe later in the week, i'll post anything i find
Cheers

YESTERDAY was the best time to invest in or make an "EAS-Rescue" kit.

Second - best time is today.

Basically, it is an inline air-tap, Schraeder valve and a T-piece, all joined with suitable lengths of air-hose.

There is one for each of the air-bags, and it 'allows' the bag to choose it's preferred air-supplier.... Through the (open) air tap from the EAS system, or -CLOSED tap - direct from any air pump / servo / manual air pump etc, through the Schraeder valve.

On the Lady Sarah, the front two live next to the PAS reservoir/above the horns, and the rear pair - sad to say - are hanging under the chassis at the rear, in front of the bumper...
But I can get to them easily, and turn off (Isolate) each wheel.

The 'cheap & cheerful' setup is... a schraeder valve in a hose fitting, and a length of hose. Again, one for each corner.... you remove the system-hose going INto each one, and replace with the above, and manually fill with air.... but good luck in fitting it to the rears when they're deflated !

P38 owners have the advantage, with the EAS system resident in the Engine Room... so it's easy to access the 4 air-hoses at the source.
