Failure Diagnosis: Notes

1. In principle, ESC and TCS controls are prohibited in case of ABS failure.
2. When ESC or TCS fails, only the failed system control is prohibited.
3. However, when the solenoid valve relay should be turned off in case of ESC failure, refer to the ABS fail - safe.
4. Information on ABS fail - safe is identical to the fail - safe in systems where ESC is not installed.
