Diagnostic procedure


STEP	INSPECTION		ACTION
1	VERIFY WHEEL UNIT IS INSTALLED TO EACH WHEEL Are all four wheels equipped with a wheel unit?	Yes	Go to the Step 3.
1		No	Install the wheel unit. (See WHEEL UNIT REMOVAL/INSTALLATION.) Register the wheel unit ID. (See WHEEL UNIT ID REGISTRATION.) Go to the next step.
2	INSPECT FOR DTCs Drive the vehicle at a speed of 25 km/h {15.5 mph} or more for 10 min or more. Is the same DTC present?	Yes	Go to the next step.
2		No	With advanced keyless system : go to the Step 4. With keyless entry system, and without advanced keyless system and keyless entry system: go to the Step 5.
3	IDENTIFY MALFUNCTIONING WHEEL UNIT (See MALFUNCTIONING WHEEL UNIT IDENTIFICATION.)		Identify the malfunctioning wheel unit. Replace the wheel unit. (See WHEEL UNIT REMOVAL/INSTALLATION.) Register the wheel unit ID. (See WHEEL UNIT ID REGISTRATION.) Go to the Step 5.
4	INSPECT FOR KEYLESS CM MALFUNCTION Turn the ignition switch off. Using the M-MDS, perform the DTC inspection for the keyless CM. Is any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ADVANCED KEYLESS SYSTEM].)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING COMPLETED Clear the DTC from the memory. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.) Drive the vehicle at a speed of 25 km/h {15.5 mph} or more for 10 min or more. Is the same DTC present?	Yes	If the malfunction recurs, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.) Configure the instrument cluster. (See INSTRUMENT CLUSTER CONFIGURATION.) Register the wheel unit ID. (See WHEEL UNIT ID REGISTRATION.) Go to the next step.
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE Are there any other DTCs present?	Yes	Go to the applicable DTC inspection. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)
6		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:

Drive the vehicle at 25 km/h {15.5 mph} or more, and send data from the wheel unit.

Select [ID_LAST] from the PID items, and monitor the data.

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.
