Replacing Antenna Unit

The antenna unit has registered an internal fault.

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the antenna module (ATM) or can be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the antenna unit.

HINT: The diagnostic trouble code (DTC) can also be stored by temporary interference in the communication with the antenna unit. If this is the case the antenna unit need not be replaced and the diagnostic trouble code (DTC) can be erased.
