• 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 Open-circuit, intermittent faults .

  Check the GPS antenna cable and carphone module connectors. Check for loose connections according to Loose connections (terminals) .

  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 Ω
  • 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 (-2004) 
  • For information about signals and connectors, see Signal description, Phone module (PHM) .

  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).
