Troubleshoot The VSA System: Self-Diagnosis
- Self-diagnosis can be classified into two categories:
-
- Initial diagnosis: Done right after turning the vehicle to the ON mode and until the ABS, VSA, and brake system indicator (amber) turns off.
-
- Regular diagnosis: Done right after the initial diagnosis until turning the vehicle to the OFF (LOCK) mode.
- When the system detects a problem, the VSA modulator-control unit shifts to fail-safe mode.
