DI_a210 — Vdc Other Controller States

Full alert identifier: DI_a210_vdcOtherControllerStates

Alert description

Drive Inverter Warning: Inputs to stability control have degraded

Potential impact

Traction control and stability control may fault due to this error, requiring greater manual input from the driver.

Set condition

The actuators required for stability control are in degraded states, so stability control is also degraded. Check tractionControlState and espActuatorState to find the specific controller that is degrading stability control. For tractionControlState, check previous DI alerts that point to specific cause of their degredation. For espActuatorState, check for ESP alerts that point to the specific cause of its degredation.

Clear condition

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