TPMS Symptom Troubleshooting - Calibration cannot be started
Calibration cannot be started
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 previously done. |
1. |
TPMS calibration check:
TPMS calibration check
?1. |
Turn the vehicle to the ON mode. |
?2. |
Check the number of miles on the gauge control module. |
?3. |
Make sure that all four tires are the correct size, specified tire pressure, same speed rating, same brand/model, and are evenly worn. |
?5. |
Check the parameter(s) below with the HDS.
