What is C0B62?

DTC code C0B62 indicates a malfunction related to the vehicle's restraint control module, often linked to the airbag system. This code is prevalent in various models, especially the 2016-2019 Ford Explorer, Toyota Highlander, and some Chrysler vehicles. When the C0B62 code is triggered, it usually signifies that there is an issue with the communication between the airbag system and the vehicle's computer.
