Go to step 3.

NO -

Reinstall the checked fuse, then go to step 7.

3. Disconnect the VSA modulator-control unit 46P connector.

4. Check for continuity between VSA modulator-control unit 46P connector terminal No. 40 and body ground.





Is there continuity?

YES -

Repair a short to body ground in the wire between the No. 4 (7.5 A) fuse in the under-dash fuse/relay box and the VSA modulator-control unit, the yaw rate-lateral acceleration sensor, and the steering angle sensor.

NO -

Install a new No. 4 (7.5 A) fuse in the under-dash fuse/relay box, then go to step 5.

5. Reconnect all connectors.

6. Check the ABS indicator, the brake system indicator, and the VSA indicator for several seconds when the ignition switch is turned to ON (II).

9. Measure the voltage between VSA modulator-control unit 46P connector terminal No. 40 and body ground.





Is there battery voltage?

YES -

Go to step 10.

NO -
