Diagnosis Procedure
NOTE: The Signal Tech II Tool [- (J-50190)] can be used to perform the following functions. Refer to the Signal Tech II User Guide for additional information.
1.TIRE PRESSURE SENSOR ID REGISTRATION
Perform tire pressure sensor ID registration. Refer to WT-21, "Work Procedure".
Can the tire pressure sensor ID registration be completed? YES >> GO TO 2.
NO >> Replace applicable tire pressure sensor. Refer to WT-61, "Removal and Installation".
2.CHECK TIRE PRESSURE
Check the air pressure of all wheels. Refer to WT-65, "Tire Air Pressure".
Is the inspection result normal? YES >> Perform DTC CONFIRMATION PROCEDURE again. Refer to WT-32, "DTC Logic".
NO >> GO TO 3.
3.CHECK TIRE PRESSURE SIGNAL
With CONSULT
