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 the correct IKTs  present?

    • Yes: GO to 2  .
    • No: The system cannot be tested without the correct IKTs  . INFORM the customer that the correct IKTs  must be present to proceed with diagnosis of the system.
  2. CHECK THE RKE OPERATION WHEN THE TPM MODULE IS IN AN AWAKE MODE
    1. Open and close the driver door.
    2. Press any button on the IKT.

    Does the RKE feature operate? 

    • Yes: GO to 3  .
    • No: GO to  4.
  3. CHECK THE RKE OPERATION WHEN THE TPM MODULE IS IN A SLEEP MODE
    1. Ignition OFF.
    2. Let the vehicle to sit for 10 minutes to allow the vehicle modules to go into a sleep mode.
    3. Press any button on the IKT.

    Does the RKE feature operate? 

    • Yes: The system is operating correctly at this time.
    • No: GO to  12.
  4. PERFORM THE NETWORK TEST ON THE TPM
    1. Using a scan tool, perform the TPM network test.

    Does the TPM respond to the scan tool? 

    • Yes: GO to 5  .
    • No: REFER to DIAGNOSTIC ROUTINE X : The Tire Pressure Monitor (TPM) Module Does Not Respond To The Scan Tool.
  5. CHECK FOR TPMS DTCs 
    1. Using a scan tool, perform the BCM self-test.

    Are any TPMS DTCs  recorded?

  6. CHECK THE RECORDED BCM DTCs  FROM THE SELF-TEST
    1. Check the recorded results from the BCM self-test.

    Is DTC B10AB:00 or DTC B1218:00 recorded? 

    • Yes: For DTC B10AB:00 GO to 7  .

      For DTC B1218:00 GO to  8.

    • No: GO to  8.
  7. RESYNCHRONIZE THE INOPERATIVE IKT
    1. Ignition OFF.
    2. Ignition ON.
    3. Ignition OFF.
    4. Press any button on the IKT.

    Does the RKE feature operate? 

    • Yes: The system is OK.
    • No: GO to 8  .
  8. MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED
    1. Ignition ON.
    2. Using a scan tool, view the BCM PIDs  .
    3. Press a button on the IKT while observing the BCM PIDs  (TIC_LAST_BC and LST_RKE_xMTR).

    Does the TIC and RKE command show up on the scan tool screen when a button is pressed? 

    • Yes: GO to 9  .
    • No: GO to  10.
  9. CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED
    1. Using a scan tool, view BCM PIDs  .
    2. Press a button on the IKT and compare the BCM PID (TIC_LAST_BC) with the PIDs  (TIC_01_BCM, 2, 3, 4, 7, 8, 9, or 10).

    Does the TIC displayed match any of the TICs  stored in memory?

  10. 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? 

    • Yes: GO to 11  .
    • 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).
  11. CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD IKT
    1. Using a scan tool, view BCM PIDs  .
    2. Use the customer's second IKT, or a known good RKE transmitter that is correct for the vehicle, press a button on the IKT while observing the BCM PID (TIC_LAST_BC).

    Does the TIC show up on the scan tool when a button is pressed? 

  12. CHECK FOR CORRECT TPM MODULE OPERATION
    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.
  13. CHECK FOR CORRECT BCM OPERATION
    1. Ignition OFF.
    2. Disconnect and inspect all BCM connectors.
    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 all BCM connectors. Make sure they seat and latch 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 BCM. REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
    • 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.
