DI_a199 — Vdc Faulted

Full alert identifier: DI_a199_vdcFaulted

Alert description

Drive Inverter Warning: Stability control (VDC) is faulted

Potential impact

Stability control is not available, requiring greater manual input from the driver.

Set condition

Stability control (also known as vehicle dynamics control or VDC) will fault if it does not receive all of its inputs or if the values of those inputs are implausible. This alert does not indicate cause, it was mostly likely set immediately after another DI alert that points to the specific cause of the fault.

Clear condition

This alert will clear on the drive cycle after the underlying fault cause has been corrected.
