ABS Modules - Do they go bad??

[aniwack]

I've got two bikes in for service both with blinking ABS lights. I did the usual check the pickup sensors for debris and gunk and both are clean. Has anyone experienced an issue with the control module itself??

I had one code and it was the control module which I replaced and about a year later I had a different code and it was the ABS pump that was bad and I replaced it.

FWIW, never had a ST1100 ABS module go bad (I would think they are similar in construct).
As you said, it is usually the sensors.
On the ST1100, if the battery is failing, the ABS will throw all kinds of error codes.
