View Full Version : Bit of a list

My Rangie has recently developed a lean to the left on a couple of occasions after driving for an hour or so. It has been faulting the eas on a reasonably regular basis and though I have changed the whole box,- valve block, pump and driver this hasn't helped.I clear the fault with a buddy box (USB TYPE)and on long runs the faulting is persistent enough to make me use the mars system and pull the plug on the pump. At least that way I dont have to stop every half to 1 hour and correct the fault.
The lean to the left is not always the way it faults but it's happened 3 or 4 times in the last few weeks.
Could the regular faulting be caused by sensor(s) out of range.
Any thoughts please.

leaky airbag?

It doesn't seem like a leaky airbag as with the manual recovery operating and the taps off and compressor disconnected I can drive 200 -300 k's with no noticeable loss of air pressure. When it decides to lean it happens in 100 metres of so.

Damned nuisance!!:( It's possible the sensor is out of range and the buddybox is simply restoring the status quo (=default values) in the ECU until the sensor starts playing up again...are FL and RL measurements equally down in relation to FR & RR? or is one LH spring dragging the other down?

The buddy box is no doubt OK for soft fault rectification but Storey wilson s/w loaded onto a PDA enables you to read what the faults are and
recalibrate.

One relatively quick method of seeing if it is a sensor is to swap the FL sensor with the FR. If this manouevre hasn't been done previously they will be tracking on previously unused parts of the rheostat ...just like new ones. If it doesn't fix things, swap the rears as well...

The SW s/w is a must have and I'd recommend you get it ASAP

Thanks for that Hoges, I will swap the sensors and see how that goes.

Is it always at the same height it leaks or does it so it on several height settings? I have seen some cracked bags leak only at certain heights as when they are lower they roll over themselves and seal up the crack/hole.

It faults mostly on smooth roads at 90-110k's. The bags were all new 3 years ago and have done about 70000k's. Sometimes I'll drive 100k's before it faults but sometimes only 10k's between buddy box fixes.The lean to the left has only happened 3 times but it's a recent change in behavior. I was wondering if a sensor may be out of range and different to the one on the other side.

Hi John

What codes does the EAS Buddy show you when you plug it in to your PC?

<putting on the sales guy hat> The main advantage the EAS Buddy has over the EAS Kicker Lite is that it stores the faults it clears for later reading on a PC/Mac. It stores the faults in a text file that can be read off the EAS Buddy just like a USB flash drive <end sales talk>

If one of your sensors is out of range due to a mechanical fault like the arm pulling out of the rubber mount (such as happened to me yesterday out near the Black Spur) then it will stay in fault until you fix the mechanical problem and then reset the fault with the Buddy.

Cheers, Paul.

Thanks Paul and all others. It's going in to Justin Coopers tomorrow to have a couple of steering bits renewed so I'll get him to look at/ change sides with the sensors. Or tell me if they are stuffed.
The buddy box messages vary from fr valve stuck closed, cant raise fr, fl valve stuck closed etc.

if the faults only occur at 90-100Kph, then your EAS will be at Highway height... maybe the range on one the potentiometers at that height is worn out? Just a thought.

The types of faults it is returning seem to indicate sticky solenoids rather than a HS problem.

You mentioned that you have replaced the EAS driver block... do you still have the old one to swap over as a test?

Cheers, Paul.

Paul, I changed the whole box and dice as my son and I have a fairly complete vehicle which he crashed last year. We found another one (same colour and all) with a blown up engine so with insurance money were able to get back on the road by transplanting the motor.
But I have been getting similar faults with either box so thought to look at things like the potentiometers and/or leaks.
Maybe know a bit more after J.C.has a look with it up on the hoist.

The problem with my p38 turned out being the front right potentiometer which was giving incorrect readings. As we have a spare/crashed vehicle to pick bits off, I replaced the crook one and the front now sits about 40mm higher and nice and level.:) The lean to the left which happuned a couple of times was caused by the right and left front airlines being crossed over. Woops.:wasntme:
