Tire Pressure Monitoring System (TPMS) - Tire Pressure Monitor Sensor (Inspection)
Correction code NA NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and 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. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.
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. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.
- Remove the LH front wheel cover. See Wheel Cover - Front - LH (Remove and Install).
-
Perform connection test on LH front TPMS
sensor.
NoteVia 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.
-
Verify LH front TPMS sensor FW ID.
NoteCT 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).
-
Troubleshoot LH front TPMS sensor
connection failure by lowering RSSI threshold.
NoteIf 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.
-
Troubleshoot LH front TPMS sensor
connection failure by increasing LF power.
NoteIf 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.
- Repeat step 1 through step 5 for the remaining wheels.
- Install the the wheel covers that have been removed. See Wheel Cover - Front - LH (Remove and Install).
