Rear Antilock indicator issue
 

I have a "Rear Antilock" light that comes and goes intermittently. I posted this Q earlier (months ago) and did search for it but can't find the replies. It stopped, not it's started again. I didn't do anything about it before. Where do I start please?

Could be a faulty speed sensor located on top of rear differential. Take it out and clean it. There are many posts on this subject in this forum. Do a search on 'rabs' ....

Thanks. It also seems to be temperature dependant. It's 65 now and no problem. It was 29 this AM early, and it was doing it. I will do the cleaning. Thanks again.
