    Yes  GO to  J7.
    No  PROGRAM a second key. REFER to Passive Anti-Theft System (PATS) - With Intelligent Access (IA) .

  7. J7 RESYNCHRONIZE THE INOPERATIVE IA KEY USING THE SECOND IA KEY

    • Ignition OFF.
    • Press any button on the operational Intelligent Access (IA) key.
    • Within 30 seconds, press a button on the inoperative Intelligent Access (IA) key.
    • Check the inoperative Intelligent Access (IA) key for correct operation.

    Does the inoperative Intelligent Access (IA) key operate now? 

    Yes  The system is OK.
    No  GO to  J8.

  8. J8 CHECK THE IA KEY

    • Place the Intelligent Access (IA) key in the backup pocket.
    • Start the engine.

    Does the engine start? 

    Yes  GO to  J9.
    No  REFER to Passive Anti-Theft System (PATS) - With Intelligent Access (IA) .

  9. J9 CHECK THE IA KEY BATTERY

    • Using a thin coin, open the Intelligent Access (IA) key.
    • Do not clean off any grease from the battery terminals on the back surface of the circuit board.
    • Verify the correct battery is used (CR2032).
    • Remove the Intelligent Access (IA) key battery and measure the voltage.

    Is the voltage greater than 2.5 volts? 

    Yes  GO to  J10.
    No  INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the Intelligent Access (IA) key (damaged or dead batteries do not erase Intelligent Access (IA) keys from memory).

  10. J10 CHECK FOR COMMUNICATION WITH THE TPM MODULE

    • Using a scan tool, perform the network test.

    Does the TPM module pass the network test? 

    Yes  GO to  J11.
    No  REFER to Module Communications Network .

  11. J11 CHECK THE TPM MODULE COMMUNICATION CIRCUIT FOR A SHORT TO VOLTAGE

    • Ignition OFF.
    • Disconnect: TPM Module.
    • Disconnect: RFA Module C2153E.
    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
