I'm trying to get my 1994 HSE back on the road this year but my first job - sorting out the EAS is not going to plan. My EAS system as always had trouble communicating with the software but I was able to establish that the likely culprit was a duff height sensor. I've since replaced the sensor but the now the software is bringing up a whole bunch of fault codes, which I believe is indicative of a communications problem, and it refuses to clear them. In all other ways the software seems to be working. i can actuate the pump, and the various messages, I can get my height sensor readings etc. The Tx/Rx values appear to be correct.

Any suggestions?

There's a button on the EASUnlock software that doesn't look like a button, it looks like a box, marked 'FAULTS'. Click on that and it clears all the faults, then you can click on Read Faults again to see remains.

Ahh, that could be it. I've always thought it was the unlock EAS button to clear faults.

If you have the V2 Free version from RSW, then the "Read Faults" button does what it says !! The "UnlockEAS" button is for clearing faults.

I always thought the Unlock EAS button allowed you to control it if it was in hard fault. However, I always go, Read Faults, Unlock EAS, Faults and then read again, that clears everything.

There's "Unlock EAS" buttons on all the tabs (except the Heights one). All of them send the same 0x7D00 sequence to clear the faults (although I'm trying it offline at the moment).

One thing I’ve forgotten to do a couple of times is to put the original Timer Relay back in, rather than the generic one I have in to prevent self levelling while parked. Probably not your issue but I thought I’d throw it in as a possibility.
