Checking connectors and wiring
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.
