alikhan Posted July 14, 2014 Report Share Posted July 14, 2014 What is ECM and BCM of a car. My friend has his own workshop, and one day he drove my Impala and told me that ECM and BCM is not working fine. I was looking at his face, as I didn’t understand what he was saying. I didn’t want to be seemed as a fool, so I didn’t say anything. Please tell me what it is? Link to comment Share on other sites More sharing options...
humair Posted July 22, 2014 Report Share Posted July 22, 2014 ECM and BCM are the control modules of the car. BCM stands for body control module which controls the door locks, lights, delay locking and every other electric internal options/units. ECM stands for engine control modue which controls the performance of the engine. Link to comment Share on other sites More sharing options...
