1. Check all four tires size, pressure, wear difference, and the wheel alignment.
Are the tire condition and wheel alignment OK?
YES - Go to step 2.
NO - Make sure the suspension is not modified, and adjust the wheel alignment correctly, and recheck by test-driving.
2. Turn the ignition switch ON (II).
3. Clear the DTC with the HDS.

8. Disconnect the sensor cluster 6P connector.
9. Disconnect the VSA modulator-control unit 47P connector.
10. Turn the ignition switch ON (II).
11. Measure the voltage between body ground and VSA modulator-control unit 47P connector terminals No. 6, No. 25, No. 29, and No. 31 individually.
Is there 0.1 V or more?
YES - Repair short to power in the wire between the VSA modulator-control unit and the sensor cluster.
NO - Go to step 12.
12. Turn the ignition switch OFF.
13. Check for continuity between body ground and VSA modulator-control unit 47P connector terminals No. 6, No. 25, No. 29, and No. 31 individually.
Is there continuity?
YES - Repair short to body ground in the wire between the VSA modulator-control unit and the sensor cluster.
NO - Go to step 14.
14. Check for continuity between VSA modulator control unit 47P connector terminals No. 6, No. 25, No. 29, No. 31 and sensor cluster 6P connector terminals No. 1, No. 3, No. 2, No. 5.
Is there continuity?
YES - Go to step 15.
NO - Repair open in the wire between the VSA modulator-control unit and the sensor cluster.
15. Substitute a known-good sensor cluster.
NOTE: Check the sensor cluster mounting base is not bent or twisted, and make sure the sensor cluster is mounted properly and fixed.
16. Reconnect all of the disconnected connectors.
17. Turn the ignition switch ON (II).
18. Clear the DTC with the HDS.
19. Turn the ignition switch OFF, then disconnect the HDS.
20. Test-drive the vehicle around a number of corners.
21. Check for DTCs with the HDS.
Is DTC 25, 26, or 104 indicated?
YES - Check for loose terminals in the VSA modulator-control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit, and retest.
NO - If any DTCs are indicated, go to the indicated DTCs troubleshooting. If DTC is not indicated, replace the sensor cluster.
