Note
For instructions on how to update the firmware on the TPMS Wake Tool, refer to the manufacturer’s instructions. Tesla employees can refer here for the TT02 tool and here for the TT03 tool.
  1. Remove the LH front wheel cover. See Wheel Cover - Front - LH (Remove and Install).
  2. Perform connection test on LH front TPMS sensor.

    Note
    Via wake tool > Conn Test > Hold wake tool near valve stem then press trigger button. If sensor fails to connect then try again. If sensor fails to connect again then proceed to troubleshooting steps. If sensor connects then proceed with current procedure.
  3. Verify LH front TPMS sensor FW ID.

    Note
    CT is B78D3739. S3XY is 69B19007. If FW ID is not for CT then record TPMS ID and FW ID and proceed to TPMS replacement procedure. See TIRE PRESSURE MONITOR SENSOR (TPMS) BLUETOOTH - NO NUT - BLACK (Remove and Replace).
  4. Troubleshoot LH front TPMS sensor connection failure by lowering RSSI threshold.
    Informational PurposesAn informational icon, calling your attention
    Note
    If sensor connected then skip this step. Reposition wake tool as needed. Via wake tool > Settings > RSSI. Negative threshold will pick up weak signal. Lower threshold then try connection again. If sensor fails to connect again then proceed to increasing LF power steps.
  5. Troubleshoot LH front TPMS sensor connection failure by increasing LF power.
    Informational PurposesAn informational icon, calling your attention
    Note
    If sensor connected then skip this step. Reposition wake tool as needed. Via wake tool > Settings > LF Power. Change to high then try connection again. If sensor fails to connect again then escalate.
  6. Repeat step 1 through step 5 for the remaining wheels.
  7. Install the the wheel covers that have been removed. See Wheel Cover - Front - LH (Remove and Install).
