Issue: A small number of trucks may have been manufactured without the wiring for the antilock braking system (ABS) for a towed trailer. Additionally, there is no warning light to advise the driver if the ABS for the trailer isn't working. Safety Risk: An antilock braking system that doesn't work could increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and advise you to take your truck to a dealership to install the ABS wiring and warning light.
