STEP	INSPECTION	ACTION
1	INSPECT INSTALLATION OF WHEEL UNIT • Inspect the wheel unit is installed correctly to each wheel. • Are all four wheels equipped with each wheel units?	Yes	Go to the next step.
No	Install the wheel unit correctly and register the wheel unit ID, 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. (See MALFUNCTIONING WHEEL UNIT IDENTIFICATION.) • Is there any malfunction?	Yes	Replace and register the malfunctioning wheel unit, then go to Step 4. (See WHEEL UNIT REMOVAL/INSTALLATION.) (See WHEEL UNIT ID REGISTRATION.)
No	Go to the next step.
3	INSPECT KEYLESS RECEIVER • Switch the ignition to off. • Inspect the keyless receiver. (See KEYLESS RECEIVER INSPECTION [KEYLESS ENTRY SYSTEM].) • Is there any malfunction?	Yes	Replace the keyless receiver, then go to the next step. (See KEYLESS RECEIVER REMOVAL/INSTALLATION [KEYLESS ENTRY SYSTEM].)
No	Go to the next step.
4	VERIFY TROUBLESHOOTING COMPLETED • Clear the DTC from the instrument cluster memory using the M-MDS. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.) • Drive the vehicle at speed of 25 km/h {15.5 mph} or more for 10 min or more. • Retrieve the TPMS DTC using the M-MDS. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.) • Is the same DTC present?	Yes	Replace the instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No	Go to the next step.
5	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)
No	DTC troubleshooting completed.

STEP

INSPECTION

ACTION

INSPECT INSTALLATION OF WHEEL UNIT

• Inspect the wheel unit is installed correctly to each wheel.

• Are all four wheels equipped with each wheel units?

Yes

Go to the next step.

Install the wheel unit correctly and register the wheel unit ID, then go to Step 4.

(See WHEEL UNIT REMOVAL/INSTALLATION.)

(See WHEEL UNIT ID REGISTRATION.)

IDENTIFY MALFUNCTIONING WHEEL UNIT

• Identify the malfunctioning wheel unit.

(See MALFUNCTIONING WHEEL UNIT IDENTIFICATION.)

• Is there any malfunction?

Yes

Replace and register the malfunctioning wheel unit, then go to Step 4.

(See WHEEL UNIT REMOVAL/INSTALLATION.)

(See WHEEL UNIT ID REGISTRATION.)

Go to the next step.

INSPECT KEYLESS RECEIVER

• Switch the ignition to off.

• Inspect the keyless receiver.

(See KEYLESS RECEIVER INSPECTION [KEYLESS ENTRY SYSTEM].)

• Is there any malfunction?

Yes

Replace the keyless receiver, then go to the next step.

(See KEYLESS RECEIVER REMOVAL/INSTALLATION [KEYLESS ENTRY SYSTEM].)

Go to the next step.

VERIFY TROUBLESHOOTING COMPLETED

• Clear the DTC from the instrument cluster memory using the M-MDS.

(See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)

• Drive the vehicle at speed of 25 km/h {15.5 mph} or more for 10 min or more.

• Retrieve the TPMS DTC using the M-MDS.

(See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)

• Is the same DTC present?

Yes

Replace the instrument cluster, then go to the next step.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Go to the next step.

VERIFY THAT NO OTHER DTCs ARE PRESENT

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.)

DTC troubleshooting completed.

• If the wheel unit has been newly replaced, the TPMS warning light may flashes before the ID registration is complete, and DTC C2011:87, C2012:87, C2013:87 and C2014:87 may be stored in the memory. In this case, reimplement 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.
