    ABS light is on. From what I’ve read, when the ABS senses wheel slip, the engine brake is shut off by the ABS. Where is this relay located? Where is the ABS computer located?

    i will have to look in my maintenance records back in 2018. I have replaced the ABS computer and at least two ABS modulator valves over the years.
