Signal Missing. Intermittent Fault

Signal missing. Intermittent fault

Checking contact resistance, oxidation and wiring

Hint: The carphone module is connected to the GPS antenna via a connector in the right-hand A-post.




- Ignition off
Check the antenna cable between the carphone module connector G (gray) and connector E (terminal 1) in the right-hand A post. Check for an open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the GPS antenna cable and carphone module connectors. Check for loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Try replacing the antenna if no fault is found in the antenna cable or connector.
Remedy as necessary.

Other information:
- The GPS antenna has an internal resistance of approximately 60 ohms
- The resistance of the antenna cable between the carphone module and the connector in the right A-post, when measured using an ohmmeter, must be infinite between the signal cable and the shield or body ground
- To access and replace the carphone antenna, see Antenna carphone, replacing
- To access or replace the carphone module, see Phone module (PHM), replacing Service and Repair

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
