1. Check the size, air pressure, and amount of wear of all four tires, and the wheel alignment.
Is 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 to LOCK (0).
3. Disconnect the sensor cluster 6P connector.
4. Disconnect the VSA modulator-control unit 47P connector.
5. Turn the ignition switch to ON (II).
6. 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 7.
7. Turn the ignition switch to LOCK (0).
8. 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 9.
9. Check for continuity between VSA modulator-control unit 47P connector terminals No. 61 No. 25, No. 29, and No. 31 and sensor cluster 6P connector terminals No. 1, No. 3, No. 2, and No. 5.
Is there continuity?
YES - Go to step 10.
NO - Repair open in the wire between the VSA modulator-control unit and the sensor cluster.
10. Substitute a known-good sensor cluster.
NOTE: Check that the sensor cluster mounting bracket is not bent or twisted, and make sure the sensor cluster is mounted properly and fixed.
11. Reconnect all of the disconnected connectors.
12. Turn the ignition switch to ON (II).
13. Clear the DTC with the HDS.
14. Do the VSA sensor neutral position memorization. Programming and Relearning
15. Turn the ignition switch to LOCK (0), then disconnect the HDS.
16. Test-drive the vehicle around a number of corners.
17. 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.
