PINPOINT TEST L : The RKE Transmitter Has Poor Range Performance

  1. L1 CHECK FOR THE CORRECT IA KEYS

    • Check that the correct Intelligent Access (IA) keys are used with the vehicle.

    Are all the correct Intelligent Access (IA) keys present? 

    Yes  GO to  L2.
    No  The system cannot be tested without the correct Intelligent Access (IA) keys. INFORM the customer that all the correct Intelligent Access (IA) keys must be present to proceed with diagnosis of the system.

  2. L2 CHECK ALL THE RKE TRANSMITTERS FOR POOR RANGE PERFORMANCE

    • Check all the RKE transmitters for poor range performance (less than 10 m (33 ft)).

    Do all the RKE transmitters experience poor range? 

    Yes  GO to  L4.
    No  GO to  L3.

  3. L3 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  REPLACE and PROGRAM the inoperative Intelligent Access (IA) key. REFER to Passive Anti-Theft System (PATS) - With Intelligent Access (IA) .
    No  INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the Intelligent Access (IA) key (weak or dead batteries do not erase keys from memory).

  4. L4 CHECK THE LOCATION OF THE VEHICLE AND THE APPROACH ANGLES AROUND THE VEHICLE

    • Make sure the poor performance is consistent in nature and is not from one approaching angle.
    • The RKE transmitter range performance may be degraded in certain locations. For example, if the vehicle is within 0.8 km (0.5 mi) of high-power devices or radio/TV towers, the operating distance of the RKE transmitters may be reduced.

    Is the poor range performance consistent around the vehicle? 

    Yes  GO to  L5.
    No  The system is operating correctly at this time.

  5. L5 CHECK FOR CORRECT TPM MODULE OPERATION

    • Ignition OFF.
    • Disconnect and inspect the TPM module connector.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the TPM module connector. Make sure it seats and latches correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new TPM module. REFER to Tire Pressure Monitoring System (TPMS) .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
