EAS sensor readings???

Finally found some time to do some more de-bugging on the RRC ('93 classic LSE).

It's had a soft fault for about 18 months, never been too much of a prob as it goes down overnight (due to a slightly leaky spring - now replaced) and it would always just go up to standard height whatever you did with the buttons.
I've been rebuilding the engine (when time allows) for the past 3 months.
Engine now all back together and running pretty well although needs a proper diagnostic check to iron out odd gremlins.

BUT after the rebuild the EAS won't do anything. Had the diagnostics read (on it's bumpstops) and he couldn't get electronic access to the ECU to clear the faults as it was right down.
I've now jumpered the plug as described on rangerovers.net repairs pages and it is up to the about the proper height.

But before I go and get it read again and reset, I wanted to repair what I think is the cause of the soft fault, one of the height sensors.

On the first diagnostic test, the 'targets' for the 4 sensors are all 20, and the actual readings (on bumpstops) were:-
NSF actual - 10; OSF actual - 56;
NSR actual - 76; OSR actual - 86.

Does this mean the NSF sensor is the one that's faulty/out of range?

The actual fault status was reported as a 'vehicle speed fault', and 'Ride state - Fault cond. C'

Can anyone translate/explain?

TIA

Your sensor settings may be a red herringi, I would test them again at ride height - I had a new sensor put on my P38 and that reads about 40 below the others, it justs depends on the sensor...

The actual faults sound like an issue with the EAS computer not getting the correct information from the BECM - if the EAS thinks that the car is doing something that it isn't it will get confused.

Can you re-set the EAS faults and take her for a drive to see if that fixes it?

Thanks for the thoughts - but it's a Classic and doesn't have a BECM (don't think they started with those till '95). I think the EAS is pretty much 'stand alone' on classics. At the moment the ECU is unplugged as if I plug it in the car sinks to the bumpstops. I can get it back up using the 4 wire jumper in the plug, but as it costs me £35 for each diagnostic/re-set, I wanted to pre-empt another soft fault by fixing what (I think) caused it.

Don't know much about Classic but have a look at www.RangeRover.net. Classic repair and diagnostics on there, it may help you.

I actually found that site when we first got the car 8 years ago, before any of the various RR fora, it's very, very useful but lacks the interactivity of a forum re specific questions . . .
