Fault-Tracing Information

Diagnostic trouble code (DTC) ATM-0004 is stored if the antenna module (ATM) detects a GPS unit even though the car is not configured for one.

A possible cause of the fault is that a GPS unit has been installed but the car configuration file has not been updated.

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.

Remedy as necessary for permanent faults
