Impact

Traction control and stability control may be unavailable due to this error. The vehicle should be driven with extreme caution if these features are unavailable.

Description

Drive Inverter Warning: Longitudinal acceleration or roll rate error.

Cause

The drive inverter is not receiving longitudinal acceleration and/or roll rate from the Restraint Control Module (RCM) properly, or their values are considered implausible. Alert log signal data for longAccel and rollRate should provide more information on the specific cause (frozen signal, signal rate limit exceeded, or CAN issue). Frozen signals or rate limits require further investigation. CAN issues should also be diagnosed and can be caused by RCM not being on the PARTY CAN bus, or by general CAN bus error frames or shorts.

Clear condition

If this alert is set due to rate or freeze check, it will clear on the next drive cycle. If the alert is set due to CAN issues it will clear on the drive cycle after the CAN issues have been resolved.
