Excessive Time To Enter Closed Loop Reductant Injection Control

Check these first

• Low battery voltage that stalls the SCR control loop
• A failed SCR sensor or injector that blocks closed loop
• A reductant level or quality fault
• A calibration issue in the SCR control software

What to do next

1. Read SCR closed loop status and reductant level on a scan tool
2. Check battery voltage under load
3. Test the SCR sensors and injector that feed closed loop
4. Check reductant quality and top off the tank
5. Reprogram the SCR control if the sensors and injector test good
6. Clear the code and retest
