DTC P062F Buick

Description

The infotainment control module (ICM) compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM). If the configuration IDs do not correspond the fault code is stored. The diagnostic trouble code (DTC) is also stored if the communication between the infotainment control module (ICM) and the central electronic module (CEM) is interrupted. Note! In the event of an open-circuit in both the control area network (CAN) cables, it is not possible to communicate with the infotainment control module (ICM). Therefore it will only be possible to read off the diagnostic trouble code (DTC) if this type of fault is intermittent. When the diagnostic trouble code (DTC) is stored, the control module responds to the diagnostic commands. However normal control area network (CAN) communication does not work (Expulsion mode).
