Vibrations are felt at 1000 rpm and 3000 rpm. DTCs are stored in the subframe mount control module. The basic settings of the active engine mounts in the subframe mount control module, J931, are deactivated when work is done on either of the vehicle electrical system control modules, J519 and/or J520 (for example, when a key is programmed). As a result, the vehicle vibrates or judders when cylinders are actively switched off.
