Checking the wiring and component
HINT: The phone module is connected to the telephone antenna via a connector in the right A-pillar.
- Ignition off.
Check the antenna cable between phone module connector F (brown) and connector E (terminal 2) in the right A-pillar for open circuit and short circuit to supply voltage.

Raise the secondary lock on the connector in the right A-pillar.
Loosen the primary lock and remove the insulator.
Carefully remove the antenna from the headlining.
Measure the resistance between the signal line and screen ground on the connector. The resistance must be approximately 0 Ω.
Measure the resistance between screen ground and ground. The resistance must be infinite.
Carefully remove the three screws that hold the antenna's circuit board.
Carefully lift up the circuit board from the mounting point so that there is no contact between the circuit board and the casing.
Measure the resistance between the signal line and screen ground. The resistance must be infinite. If the resistance is infinite there is a short-circuit between the signal line and screen ground.
Remedy as necessary.

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
