Tire Pressure Monitoring System (TPMS) - Tire Pressure Monitor Sensor (Inspection)

Correction code NA NOTE: Unless otherwise explicitly stated in the procedure, the correction code and its associated FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so. NOTE: See Flat Rate Times to learn more about FRTs and how they are created. NOTE: See Personal Protection to make sure you are wearing proper PPE when performing the procedure below. NOTE: See Ergonomic Precautions for safe and healthy working practices.

Warning
This procedure is a DRAFT. Although it has been validated, Warnings and Cautions might be missing. Follow safety requirements and use extreme caution when working on or near High Voltage systems and components.
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 Sensor - TPMS - Front - LH (Remove and Replace).
  4. Troubleshoot LH front TPMS sensor connection failure by lowering RSSI threshold.
    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.
    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).
