Pinpoint Test

1. Check that the correct IA keys are used with the vehicle. REFER to Intelligent Access (IA) Key .

Are all the correct IA keys present? 

• Yes: GO to 2  .
• No: The system cannot be tested without the correct IA keys. INFORM the customer that all the correct IA keys must be present to proceed with diagnosis of the system.

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  .

1. Using a thin coin, open the IA key.
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 IA key battery and measure the voltage.

Is the voltage greater than 2.5 volts? 

• Yes: REPLACE and PROGRAM the inoperative IA key:

  REFER to ERASE ALL KEYS AND PROGRAM TWO KEYS ,

  REFER to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT , or

  REFER to KEY PROGRAMMING USING TWO PROGRAMMED KEYS .

• No: INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the IA key (weak or dead batteries do not erase keys from memory).

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.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 5  .
• No: The system is operating correctly at this time.

1. Ignition OFF.
2. Disconnect and inspect 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.
