Diagnostic Trouble Code (DTC) Information ICM-U01564A
Condition
The serial number of each control module in the infotainment system is stored in the central electronic module (CEM). The stored numbers are compared with the serial numbers of the control modules at start up. If the numbers do not correspond, that particular control module is blocked and the function is not available.
The blocking function for non-approved control modules is designated Infotainment Theft Protection (ITP).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Infotainment Control Module (ICM) not included in valid list.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on for at least 12 seconds.
- Battery voltage higher than 11 V.
- Infotainment Theft Protection (ITP) activated.
The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
Substitute Value
- None.
Possible Source
- Replacement of the Infotainment control module (ICM) invalid according to the valid list stored in the central electronic module (CEM).
