Reductant level low.
â–¶ How to fix
1. Fill up reductant. 2. If the reductant level is high and the fault still remains, check the harness and connectors between the EEC control unit (E67) and the reductant pick-up unit (T116) for electrical failures. 3. If no electrical failures are detected, change the reductant pick-up unit.
