Pinpoint Test

  1. CHECK FOR THE CORRECT IKTs 
    1. Check that the correct IKTs  are used with the vehicle. REFER to Integrated Keyhead Transmitter (IKT) .

    Are all the correct RKE transmitters present? 

    • Yes: GO to .
    • No: The system cannot be tested without the correct RKE transmitters. INFORM the customer that the correct RKE transmitters must be present to proceed with diagnosis of the system.
  2. CHECK ALL THE RKE TRANSMITTERS FOR POOR RANGE PERFORMANCE
    1. NOTE: The 20 m (65.62 ft) measurement of range is not the standard but is a guideline that clearly indicates a vehicle is experiencing normal range performance.

      Check all the RKE transmitters for poor range performance (less than 20 m (65.62 ft)).

    Do all the RKE transmitters experience poor range? 

    • Yes: GO to  4.
    • No: GO to .
  3. CHECK THE IKT BATTERY
    1. Using a thin coin, open the IKT.
    2. Do not clean off any grease from the battery terminals on the back surface of the circuit board.
    3. Verify the correct battery is used (CR2032).
    4. Remove the IKT battery and measure the voltage.

    Is the voltage greater than 2.5 volts? 

  4. CHECK THE LOCATION OF THE VEHICLE AND THE APPROACH ANGLES AROUND THE VEHICLE
    1. Make sure the poor performance is consistent in nature and is not from one approaching angle.
    2. 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 .
    • No: The system is operating correctly at this time.
  5. CHECK FOR CORRECT TPM MODULE OPERATION
    1. Ignition OFF.
    2. Disconnect the TPM module connector.
    3. 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
    4. Reconnect the TPM module connector. Make sure it seats and latches correctly.
    5. 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 MONITOR (TPM) MODULE .
    • 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.
