ABS Light Can Using A Spare Tire Make The ABS Light Come On

I’m looking to buy a 96 Chevy Truck, z71. I test drove it and the “Anti Lock Breaks” light stayed on. The owner said it was because of the flat tire and having the spare on. (left front) Is this correct?
I thought the sensors were in the rotors. Oddly, while I was driving it, I hit the brakes while on ice and the wheel with the spare locked up, the others didn’t.
Simply, Can using the Spare Tire cause the “Anti-Lock Brakes” light to come one?
