TPMS Symptom Troubleshooting - TPMS cannot be calibrated
TPMS cannot be calibrated
NOTE:
|
|
If any gauge control module or VSA system DTCs are indicated, do the troubleshooting for these DTCs first. |
|
|
Check the number of miles on the gauge control module. After proceeding TPMS calibration, DATA LIST with the HDS shows the same number of miles on the gauge control module. When TPMS switch is not working, DATA LIST with the HDS shows the number of miles of the last TPMS calibration done before. |
