• 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 a short-circuit to ground according to Short-circuit to ground, permanent faults . Take readings at connector G between:

  • A (antenna signal) and B (shield ground)
  • A (antenna signal) and body ground.

  Try replacing the antenna if no fault is found in the antenna cable. See Antenna, carphone, replacing .

  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) .
