Diagnostic Trouble Code (DTC): Self-diagnosis
- Self-diagnosis can be classified into two categories:
- Initial diagnosis: Done right after the ignition switch is turned ON (II) and until the ABS and VSA indicators go off.
- Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned OFF.
- When the system detects a problem, the VSA modulator-control unit shifts to fail-safe mode.
