No Signal. Intermittent Fault
No signal. Intermittent fault
Checking contact resistance, oxidation and cables
Hint: The phone module is connected to the GPS antenna via a connector on the right A-pillar.
- Ignition off.
Check the antenna cable between the phone module (PHM) connector G (grey) and connector E (connector 1) on the right A-pillar for an open circuit as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check GPS-antenna cable and phone module (PHM) connectors for a loose contact, as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
If no fault is found on the connectors or antenna cable, test again after replacing antenna.
Do the necessary corrective action.
Additional information:
- In terms of DC voltage, the GPS antenna has a fixed internal resistance of approximately 60 (.
- Using an ohmmeter, the resistance between the signal wire and mudguard or body ground antenna cable, between the phone module (PHM) and the right A-pillar connector should be infinite.
- To access/replace the phone antenna, see Antenna carphone, replacing Service and Repair.
- To access/replace the phone module (PHM), 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).
