Default ABS problem

Hello, So I am working on my 89 6 spd coupe ABS. The ABS light comes on and stays on. When I turn on the key. I can hear the module relay click. Is the pump supposed to do anything? Any noise or vibration. I have replaced the two relays on the pump motor and I ordered the module relay.
The sensors have good resistance about 1 K ohm.

Thank you

When you shift the transmission into drive and the car starts to roll, the ABS pump should do a self check cycle. It should sound like a buzz or whirl sound for a few seconds.

Thank you. But, my car does not have a drive, LOL. It's a 6 spd. But I know what you mean. Can I do this with the car on a lift? Thanks again
