The GPS antenna takes too much current or is short circuited.
Turn off the ignition and wait 10 seconds before you turn it on. Wait 30 seconds while the communication node starts up. Clear all fault codes. Wait 30 seconds Read out fault codes. If this fault code remains examine the GPS antenna visually. Disconnect the antenna cables from the antenna and examine the connectors visually. Then check the continuity in the disconnected GPS antenna cables using a multimeter.
What you'll see
No driver-visible symptom recorded.
System reaction
The positioning information in the following functions does not work. - Geofence - Positioning - Vehicle and driver data - Vehicle alarm - Active prediction - GPS on CAN
Diagnostic depth
High current can be measured in antenna loop. The DTC becomes active when there is a short cut in the GPS-antenna connection for more than 25s.
The GPS antenna cable is short circuited. The GSM/GPS antenna is broken. A non-compatible GPS antenna is connected (shall be a 3.3V active antenna).
