DTC CONFIRMATION PROCEDURE
1.PERFORM SELF DIAGNOSTIC RESULT
With CONSULT
Is DTC C1704, C1705, C1706, or C1707 detected? YES >> Proceed to WT-24, "Diagnosis Procedure".
NO >> Inspection End.
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-24, "DTC Logic".
NO >> GO TO 3.
3.CHECK TIRE PRESSURE SIGNAL
With CONSULT
Monitor item |
Displayed value |
AIR PRESS FL | Approximately equal to value indicated on tire gauge for front LH tire |
AIR PRESS FR | Approximately equal to value indicated on tire gauge for front RH tire |
AIR PRESS RR | Approximately equal to value indicated on tire gauge for rear RH tire |
AIR PRESS RL | Approximately equal to value indicated on tire gauge for rear LH tire |
Is the inspection result normal? YES >> Inspection End.
NO >> Repair or replace malfunctioning components.
