DTC P203F Reductant Level Too Low


DESCRIPTION

The Urea SCR system purifies NOx using urea solution.
When the remaining quantity of urea solution is running low, the system can no longer purify NOx. Therefore, the remaining distance that can be driven is displayed on the multi-information display. When the remaining drivable distance reaches 0 km/h (0 mile), the engine cannot be started.
