That's not what I heard. I thought the question was will the ABS light come on if the sensor is bad. However, if it's push button 4wd I could see that causing a problem as well. But, typically the most common 4wd not engaging problems I have fixed are due to a bad vacuum line to the transfer case. Is your speed sensor known to be bad?
