ABS, Brake Light keep coming on intermittenly on the dashboard panel

I had the service center hook up the diagnostics and reset, b ut the lights keep coming on and off. We have cleaned the sensors. Would it be possible the sensors are bad??
Please advise

Do a voltage check. Test #9 on OBC works or,with engine running put a volt meter on the +/- battery terminals (or B+ jumper post and ground) and see if she gives at least 13.5 VDC. Thes cars are very critical of voltage and the lest stry form normal on my 1988 750 sets off all kinds of prompts. If yu do not have the hidden OBC codes, email me and I will provide: [email protected]. These are E32 codes but may work on others as well.

Thanks. I sent you an email for the OBC codes.
