DTC Trigger
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets when the internal temperature of the steering gear exceeds a temperature threshold. This is most likely due to high ambient temperature conditions, heavy loads on the steering gear, or a damaged PSCM housing allowing heat into the steering gear. Consult the DTC Index for additional information if needed.
