Pinpoint Test
- CHECK FOR THE CORRECT IKTs
- 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 2 .
- 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.
- CHECK ALL THE RKE TRANSMITTERS FOR POOR RANGE PERFORMANCE
-
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
- Using a thin coin, open the IKT.
- 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 IKT battery and measure the voltage.
Is the voltage greater than 2.5 volts?
- Yes: REPLACE the inoperative IKT and PROGRAM the IKT individually or PROGRAM all the IKTs
:
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 .
If all the IKTs are to be programmed, INFORM the customer that any IKTs not present need to be programmed.
- No: INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the IKT (weak or dead batteries do not erase TICs from memory). TEST the system for normal operation.
- 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 5 .
- No: The system is operating correctly at this time.
- CHECK FOR CORRECT TPM MODULE OPERATION
- Ignition OFF.
- Disconnect 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 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.
