SSM 47402

When performing diagnostics for DTCs P2201, P2452, P2459, P246C and/or P2463, a manual regeneration and diesel particulate filter (DPF) parameter reset using the appropriate scan tool may need to be performed. To perform the manual regeneration, go to the Toolbox tab > Powertrain > Service Functions > Diesel Particulate Regeneration System > DPF Manual Regeneration. The scan tool may indicate that a regeneration of the DPF is not recommended at this time, selecting YES on this screen will allow the regeneration process to complete. To perform the DPF parameter reset, go to the Toolbox tab > Powertrain > Service Functions > Diesel Particulate Regeneration System > DPF Parameter Reset.
