| Condition | Some customers may comment on Service Engine Soon (SES) Lamp being illuminated and/or "Service Emissions System" message on the Driver Information Center (DIC). Technicians may find DTC P205B set active or in history. |
| Cause | This is caused by a software anomaly in the Reductant Control Module. |
CORRECTION
If you encounter a vehicle set with DTC P205B currently active (displaying the "Service Emission System" message and SES Lamp illuminated) or in history (SES Lamp illuminated or not illuminated):
1. Using the service programming system, install the latest available calibration in the reductant controller.
2. Clear DTCs and perform the Reductant System Tamper Service Bay Test to clear the message from the DIC.
If the Service Engine Soon (SES) Lamp illuminated and/or "Service Emissions System" message remains displayed on the Driver Information Center (DIC), follow the appropriate SI procedures for normal diagnosis.
