General Troubleshooting Information: Self-diagnosis
- Self-diagnosis can be classified into two categories:
- Initial diagnosis: Done right after the ignition switch is turned to ON (II) and until the ABS, VSA, and brake system indicator (amber) go off.
- Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to LOCK (0).
- When the system detects a problem, the VSA modulator-control unit shifts to fail-safe mode.
