NOTE: For DTCs P21DD and/or P204C, this can indicate a concern with connector C3613. For
DTCs P21CD and/or U02A2, this can indicate a concern with connector C4851.
1. Disconnect and inspect C3613 (16 pin connector) at the reductant pump/heater assembly and C4851 (4
pin connector ) at the reductant level sensor/quality module for signs of corrosion. Refer to Workshop
Manual (WSM), Section 303-08 and Wiring Diagram, Cell 27.
(1). Inspect both the harness side and component side of both connectors for signs of water intrusion.
Focus on pins 4, 9 and 11 at connector C3613 and pins 1 and 4 at connector C4851. Inspect for signs
of:
• Visible green corrosion on multiple terminals on the harness side of connector C3613. (Figure 1)
• Corroded pin 11 on the reductant pump/heater assembly at connector C3613. (Figure 2)
• Corroded pin 9 on the reductant pump/heater assembly at connector C3613 (Figure 3)
• Visible green corrosion on the reductant level sensor/quality module side of connector C4851. (Figure 4)
• Visible green corrosion on the harness side of connector C4851.(Figure 5)

2. Replace the reductant harness, the reductant pump/heater assembly and/or the reductant tank based
on which connectors show signs of corrosion or water intrusion. Refer to WSM, Section 303-08.
(1). If there are no signs of corrosion present within either connector but signs of water intrusion
appear to be present, replace only the reductant harness.
(2). If there is corrosion present on the harness or component side of connector C3613, replace the
reductant harness and the reductant pump/heater assembly.
