Description

Drive Inverter Warning: Traction control (TC) is disabled.

Cause

This alert sets any time traction control is not available. This is almost always due to the system being faulted. To diagnose the cause of the fault, check this alert's payload to identify which inputs are in a degraded state. <br>Steps to find cause:<br>1) If velocityEstimatorState is degraded, check other DI alert for velocityEstimatorState to find the root cause. If velocityEstimatorState is normal: <br>2) If btcTargetState or ptcTargetState are degraded, check for CAN bus issues (these signals come from ESP) or sensor issues with ESP (check associated ESP alerts). If target states are normal: <br>3) If addState is degraded, check for other DI alerts about ADD. If slaveADDState is degraded, check for DIS alerts about ADD and check for other DI alerts indicating CAN communication issues with DIS.

Clear condition

This alert will clear on the drive cycle after traction control is re-enabled or un-faulted.
