eas fault

I have a 95 soft dash classic which I’ve owned and maintained for 21 years. Apart from changing the airbags some time ago I have had no problem with its EAS. However, I returned to my car a while back to find it had lowered to its bump stops. When I started the car, I saw no initial lights on switches and nothing happened. With reference to the trouble shooting manual I tested all the fuses and ran through test AA, batt on pin 1, earth on pin 18, batt on pin 34, and 0-12v on pin 12 which would indicate a faulty ecu. The results were as indicated but I was surprised the batt at pin 34 was only 0.02v. Can anyone confirm this and if so, any suggestion as to where I can get the ecu tested?

Having read many posts, I have also checked the compressor - needed a new piston seal, the thermal switch, the air drier- new filters fitted, the delay relay, the compressor relay, the warning light relay, and the other connections to the ecu plug. Are there any more checks you think I could make before getting the ecu test?
