Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY WHEEL UNIT IS INSTALLED TO EACH WHEEL
•  Visually inspect the wheel unit.
•  Are all four wheels equipped with a wheel unit?
Yes
Go to the next step.
No
Install and register the wheel unit, then go to Step 4.
(See WHEEL UNIT REMOVAL/INSTALLATION.)
(See WHEEL UNIT ID REGISTRATION.)
2
IDENTIFY MALFUNCTIONING WHEEL UNIT
•  Identify the malfunctioning wheel unit.
•  Is there any malfunctioning wheel unit?
Yes
Replace and register the malfunctioning wheel unit, then go to the next step.
(See WHEEL UNIT REMOVAL/INSTALLATION.)
(See WHEEL UNIT ID REGISTRATION.)
No
Go to the next step.
3
VERIFY TROUBLESHOOTING COMPLETED
•  Perform the Clearing DTCs Procedure.
•  Drive the vehicle at a speed of 25 km/h {15.5 mph} or more for 10 min or more.
•  Perform the Reading DTCs Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs:
•  Replace the instrument cluster, then go to the next step.
No
Go to the next step.
4
VERIFY AFTER REPAIR PROCEDURE
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)
No
DTC troubleshooting completed.

Note
•  If the installed wheel unit ID number is known, verification of whether the instrument cluster is receiving data from the wheel unit can be easily confirmed using the following procedure:
1.  Drive the vehicle at 25 km/h {15.5 mph} or more, and send data from the wheel unit.
2.  Select ID_LAST PID and monitor the data. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)
3.  Verification that the instrument cluster is receiving data is possible if the monitored ID number matches the installed wheel unit ID number.
•  If the wheel unit has been newly replaced, the TPMS warning light may flashes before the ID registration is complete, and DTC U2616, U2617, U2618 and U2619 may be stored in the memory. In this case, re-implement the wheel unit ID registration, and after confirming that the TPMS warning light is no longer flashing, erase the DTC. If the TPMS warning light does not go out, a malfunction on any one of the wheel units may have occurred and the ID registration will not have been correctly performed. Repeat the diagnostic procedure from Step 1 and perform and inspection.
