DTC 73

DTC 73: Yaw Rate Sensor (Power Supply)

1. Disconnect the yaw rate-lateral acceleration sensor 4P connector.
2. Turn the ignition switch ON (II).
3. Measure voltage between body ground and yaw rate-lateral acceleration sensor 4P connector terminal No. 1.





Is there battery voltage?

YES - Go to step 5.

NO - Repair open or high resistance in the wire between the No. 31 (7.5 A) fuse in the under-dash fuse/relay box and the yaw rate-lateral acceleration sensor.

4. Turn the ignition switch OFF.
5. Reconnect the yaw rate-lateral acceleration sensor 4P connector.
6. Clear the DTCs with the HDS.
7. Turn the ignition switch OFF, then turn it ON (II).
8. Check for DTCs with the HDS.

Does the VSA indicator come on, and is DTC 73 indicated?

YES - Check for loose terminal in the yaw rate-lateral acceleration 4P connector. If connection is good, replace the VSA modulator-control unit.

NO - Intermittent failure, the system is OK at this time. Check for loose or poor connections.
