Help - need ECU for 1997 U320

My abs light stays on. The mechanics diagnostic is that the ECU module needs replacement. I  can't find a replacement part anywhere. Anyone have the same problem? It's a Midland ECU part #:384198001. Called meritor and they tell me it should be a 10 digit number and they can't help me.

Any chance moisture got to anything?

Those ECU modules are pretty robust. It is more likely that you have a bad wheel sensor, one is out of adjustment, or has come unplugged.

The rear fast acting brake valve could be causing a bad feedback to the ECU causing the light to stay on. Its located right above the driveshaft U joint.  This location results in grease being slung up into the exhaust ports causing problems. It could also have come unplugged causing the light.

Do you still get 3 clicks when you turn the key to the run possession as the brake system goes through the self check?
Did the light come on (and stay on) after either some work or you ran over some road trash? 
The thig is with that system you will still have brakes, just not the ABS part.

This is FYI:  On that age coach the ABS light should stay on after you start the engine and start rolling till you get to about 4MPH.
