Thread: EAS emergency air-up kits

That's the right attitude Gordon I'm still waiting for you to get it sorted, and I wouldn't want to be the "weakest link"

Cheers Ken

The supension will drop to approx access height for any bus-reported ABS fault or for loss of contact with the ABS ecu. Braking a wheel speed sensor wire can and does occur and is an ABS fault, and the vehicle does drop. It is not a suspension fault but a special precaution taken by the suspension ecu just because it can - another nanny looking after people but without consideration of where the vehicle might actually be.

The fitting on the dryer outlet to the reservoir valve block is a simple plastic push-in connector without an internal ferrule, so I can't understand why these would not be suitable for emergency use for the air springs with their much lower pressures. I already carry 6 mm plastic joiners of the type used by my truck.

In some cases maybe, but it will depend on the output of the plausibility algorithms. A single speed or height sensor failing will normally bring on an amber warning and an attempt to freeze the car at the current height. Two sensors out or a continual failure of one will result in a red warning and a drop to the bump stops. This is significantly lower than access - try disabling 2 height sensors. This height setting is not set via the height sensors - no amount of fiddling with their output will raise the car. A similar scenario exists for multiple speed sensor failure or a combination of either.

Gordon, Plausibility algorithms...........what the????
Hope you don't use too many of those big words at the Melbourne training night!
Cheers, Craig

I agree with what you are saying regarding suspension faults, but an ABS fault is not a suspension fault yet the vehicle will be lowered.

agreed, and that is just annoying as there is no reason for it to do this. Typically you'll also lose Terrain Response, all gears except for third, no low range either, speed will be limited and the dash will show a warning about wearing clean underwear in case you get run over followed by an automatic hand extending to wipe your nose.

Hmmmmmmm...I haven't got that, must be the software upgrade
