--- | --- | ---
1 | PERFORM WHEEL UNIT ID REGISTRATION • Connect the M-MDS to the DLC-2. • Display the wheel unit ID registration condition (ID and tire pressure table) using the M-MDS. (See TIRE PRESSURE MONITORING SYSTEM (TPMS) ON-BOARD DIAGNOSIS.) • Temporarily remove the battery and reinstall it immediately. Note • If the battery is removed, the tire pressure data for WU1_P to WU4_P stored in the instrument cluster is reset. • Tire pressure is 0 kPa {0 kgf/cm2, 0 psi}when it is displayed again using the M-MDS. • Set the tire pressure for the four wheels separately. • Perform the wheel unit ID registration using the M-MDS. (See WHEEL UNIT ID REGISTRATION.) • Can the ID be registered? | Yes | Symptom troubleshooting completed. Adjust the tire pressure on four wheels, and then return the vehicle to the customer.
No | Go to the next step.
2 | IDENTIFY UNREGISTERED WHEEL UNIT • Identify the malfunctioning wheel unit. (See MALFUNCTIONING WHEEL UNIT IDENTIFICATION.) • Is the wheel unit for which the ID could not be registered a new wheel unit? | Yes | Replace with a new wheel unit, then go to Step 4. (See WHEEL UNIT REMOVAL/INSTALLATION.)
No | Go to the next step.
3 | Replace the old wheel unit, then go to the next step (any malfunction on an old wheel unit which has not been replaced). (See WHEEL UNIT REMOVAL/INSTALLATION.)
4 | PERFORM WHEEL UNIT ID REGISTRATION • Perform the wheel unit ID registration using the M-MDS again. (See WHEEL UNIT ID REGISTRATION.) • Can the ID be registered? | Yes | Symptom troubleshooting completed.
No | Verify the symptom troubleshooting again and return to Step 1, if the malfunction recurs.
