7. Within 2 minutes of the horn sounding, place the activation tool on the RF tire sidewall opposite (180°) from the valve stem to train the RF tire
pressure sensor.
8. NOTE: Do not wait more than 2 minutes between training each sensor or the VSM will time out and the entire procedure must be repeated.
Repeat Step 7 for the RR and LR tires.
The procedure is completed after the last tire has been trained. When the training procedure is complete, the message center (if equipped) will
display TIRE TRAINING COMPLETE.
For vehicles not equipped with a message center, successful completion of the training procedure will be verified by turning the ignition switch to
the OFF position without the horn sounding. If the horn sounds twice when the switch is turned to the OFF position, the training procedure was not
successful.
9. Using the scan tool, locate the updated TPMS sensor IDs trained to the VSM and document them on the applicable warranty claim.
10. NOTE: This step is required to clear DTC C2780, cause the VSM to exit the manufacturing mode and to make sure there are no other concerns
with a newly programmed VSM.
If the sensors are being trained due to the installation of a new VSM, clear any DTCs and perform the VSM on-demand self test.
