Details of the Chrysler u0422 OBD Code
The Chrysler U0422 code indicates a communication problem between the body control module and the powertrain control module.
Chrysler OBD code U0422 means Invalid Data Received From Body Control Module.
This code is triggered when the Powertrain Control Module (PCM) receives invalid data from the Body Control Module (BCM) over the Controller Area Network (CAN) bus.
The BCM is responsible for controlling various body functions such as lighting, power windows, and door locks.
When the PCM detects invalid data from the BCM, it sets code U0422. This can be caused by wiring issues, a faulty BCM, or a communication error on the CAN bus.
