4 Frequently Asked Questions about “What does it mean that BCM has lost communication with the base station - Williamson Battery Technologies”

What is an example of a Body Control Module (BCM)?

An example of a Body Control Module (BCM): The code may be detected when the ECM has not received an emission-related CAN signal from the BCM for at least two seconds. Note: This DTC is basically identical to U0141, U0142, U0143, U0144, and U0145.

What does a bad BCM code mean?

The code, depending on the year, make and model of the vehicle, may mean that the BCM is bad, that the BCM is not receiving or sending a signal, the BCM harness has an open or short, or that the BCM is not communicating with the ECM via the controller area network – the CAN communication line.

What is ECM communication loss?

ECM communication loss means that the ECM is unable to send or receive data from other vehicle components. Modern vehicles and machines use a Controller Area Network (CAN bus) system to facilitate communication between different modules.

What does u0140 mean on a PCM?

This exchange of information is monitored continually, and should the PCM detect a break in communication between itself and any part of the system that is controlled by the body control module, it will set code U0140, and depending on the application and the nature of the failure, may also illuminate a warning light.
