How to 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 (red) go 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.
