| DTC 25: | Yaw Rate Sensor |
| 1. | Clear the DTC. |
| 2. | Turn the ignition switch OFF, then turn it ON (II) again. |
| 3. | Test-drive the vehicle around a nunmber of corners. |
| 4. | Verify the DTC. Is DTC 27 or 64 indicated? YES - Do the appropriate troubleshooting for the DTC.n NO - Go to 5. |
| 5. | Turn the ignition switch OFF. |
| 6. | Disconnect the VSA control unit 47P connector, steering angle sensor 5P connector and yaw rate/laterral acceleration sensor 5P connector. |
| 7. | Turn the ignition switch ON (II). |
| 8. | Measure the voltage between body ground and the VSA control unit 47P connector terminal No. 33, No. 34, and No. 35 individually. Is there 1 V or more? YES - Repair short to power in the wire between the VSA control unit and the yaw rate/lateral acceleration sensor.n NO - Go to 9. |
| 9. | Turn the ignition switch OFF. |
| 10. | Check for continuity between body ground and the VSA control unit 47P connector terminal No. 33, No. 34, No. 35 individually. Is there continuity? YES - Repair short to body in the wire between the VSA control unit and the yaw rate/lateral acceleration sensor.n NO - Go to 11. |
| 11. | Check for continuity between the VSA control unit 47P connector terminal No. 35 and yaw rate/lateral acceleration sensor 5P connector terminal No. 2. Is there continuity? YES - Go to 12. NO - Repair open in the wire between the VSA control unit and the yaw rate/lateral acceleration sensor.n |
| 12. | Check for continuity between the VSA control unit 47P connector terminal No. 33 and yaw rate/lateral acceleration sensor 5P connector terminal No. 4. Is there continuity? YES - Go to 13. NO - Repair open in the wire between the VSA control unit and the yaw rate/lateral acceleration sensor.n |
| 13. | Check for continuity between the VSA control unit 47P connector terminal No. 34 and yaw rate/lateral acceleration sensor 5P connector terminal No. 3. Is there continuity? YES - Go to 14. NO - Repair open in the wire between the VSA control unit and the yaw rate/lateral acceleration sensor.n |
| 14. | Substitute a known-good yaw rate/lateral acceleration sensor |
| 15. | Reconnect all of disconnected connectors. |
| 16. | Clear the DTC. |
| 17. | Test-drive the vehicle around a nunmber of corners. |
| 18. | Verify the DTC. Is DTC 25 indicated? YES - Replace the VSA modulator-control unit.n |
