I have a 2001 Astro with aprox. 148000 mi, and both the ABS and Brake lights on the dash have been going on and off intermittently for several weeks now. I have checked the fluid and it is full. It's dark and needs to be flushed, but, it is full. I have also removed both front wheels and have cleaned the sensors with brake cleaner and contact cleaner as well as removing them and scraping the mounting plate to ensure a good contact. This van is rear wheel drive and has disc in the front and drums in the back. I don't see any sensors on the back so I assume that sensors only go on the disc brakes. I have unplugged all of the connectors at the ABS module and cleaned them with contact cleaner as well. Whenever I disconnect the battery for any of this work, the lights stay off for as long as several days and then they come back on. I have had a mechanic scan it and he says that the EBCM is going bad. He didn't write down or remember the codes so I can't look them up. Is there anything that I have missed? I can't find where the sensors plug in to check those connections. I have gotten so many different opinions and answers that I'm not sure where to turn next.
Thanks for your help,
