I'm shopping for a Disco I, and in test driving one recently I noticed the "ANTILOCK" light was on as it was idling in Park, and for the first 50 feet of travel. The person trying to sell the truck assured me that all Discos have this light on at start up and for a bit of travel. Is this true?

Thanks in advance

 

It is probably in a self test mode, which is a normal and some times slow process for the D1's. I wouldn't worry about it.
