U0140 Lost Communication With Body Control Module

This generic "U" trouble code applies to all car makers and indicates a problem between the PCM and the body control module. This is likely the result of a problem in the data link between the two modules.

Is the U0140-LOST COMMUNICATION WITH BODY CONTROL MODULE also set?
YES: Follow the diagnostics for U0140-LOST COMMUNICATION WITH BODY CONTROL MODULE
Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test
NO: Replace and program the Powertrain Control Module.

What is a manufactures body code?


Many trouble codes are "manufacturer specific" - the actual code description only applies to that manufacturer. There are 3 or 4 varieties of codes- the best known are P codes meaning "powertrain" codes (related to the engine and drive train). Some are B codes, or body codes, and when you have a Body Control Module, or BCM, a small computer that controls interior electrical circuits and systems (like lights, door locks, etc.), the codes will be stored in the BCM, although the communication between the BCM and the vehicle's main computer-the PCM (powertrain control module) will let the codes be transmitted between them. That is why the main computer can display all codes on the vehicle, whether P codes, B codes, C codes (related to ABS system), or U codes (related to communication links between the modules.

Where is the Body Control Module located?


I'm just curious if your aware of the BCM function's on your vehicle an if you know what the gate way module is ? An do you know about serial data communication between modules ? An do you know what the power mode master is ? And do you know the BCM needs programming ?
The body control module (BCM) in this vehicle functions as a gateway or translator. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss for communication between the various modules. The gateway will interact with each network according to that network's transmission protocol.
One example of this necessary communication is the communication between the engine control module (ECM)/powertrain control module (PCM) which is high speed serial data and Theft Deterrent Module which is low speed serial data. If these modules can not exchange information, the vehicle will not start.
Communication between the BCM and a scan tool can be on the high speed GMLAN network or low speed GMLAN network. If one network is lost, the BCM can still communicate with the scan tool. A lost communication DTC typically is set in modules other than the module with a communication failure.

U0184 00
Lost Communication with Radio , did you replace factory radio ?
The communication among control modules is performed through the High speed GMLAN serial data circuits and the Low speed GMLAN serial data circuit. The modules that need real time communication are attached to the High Speed GMLAN network. The body control module (BCM) is the gateway between the high and low speed networks. Refer to Body Control System Description and Operation for more information about the gateway.
Signal supervision is the process of determining whether an expected signal is being received or not. Some messages are sent on a periodic basis and are interpreted as a heartbeat of a device. If such a signal is lost, the signal supervision part of the software will set a no communication DTC (U code) against the missing device. This code is mapped on the scan tool screen as a code against the physical device. A lost communication DTC typically is set in modules other than the module with a communication failure.
Does the vehicle start an run ?

lost communication with the BCM /body module - it means that the ECM / engine management module can't communicate with the body module, the one that controls the security in the key.
2 possible causes: either the body module has failed and it will have to be replaced and paired with the ECM (this is a job for a dealer or a well equipped shop) or you have a loose connection in the wiring. In that case and if you have some basic car electrical system knowledge you can check it yourself - remove some of the dash's and steering column's panel and check the connectors. Otherwise take it to a good repair shop.
