Step 2. Visual inspection

Check each tire and wheel visually for installation condition, crack and damage. When anything abnormal is found, repair or replace.

Step 3. DTC check, record and clearance

DTC indicates malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the past and the normal condition has been restored now. To check which case applies, clear DTC once and check whether or not any fault exists.

Step 4. Problem symptom confirmation and recheck DTC

Check if what the customer claimed in "Customer questionnaire" is actually found in the vehicle and if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer if possible.) Check warning light related to TPMS system referring to LOW TIRE PRESSURE WARNING LIGHT CHECK . Drive vehicle at 40 km/h (25 mph) for 10 minutes or more and then recheck DTC referring to DTC CHECK .

Step 5. DTC troubleshooting

Based on the DTC indicated in Step 3 and referring to the applicable DTC diag. flow, locate the cause of the trouble, namely in a sensor, receiver, wire harness, connector, BCM or other part and repair or replace faulty parts.

Step 6. Intermittent Problem Check

Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.).

Step 7. Final Confirmation Test

Confirm that the problem symptom has gone and the TPMS is free from any abnormal conditions. If what has been repaired is related to the malfunction DTC, clear the DTC once and then performing driving test, and confirm that no DTC is indicated.
