This is Emissions Recall J35. Regeneration Strategy It is Emission related and is Mandated by the Federal Government. Subject of Recall J35 - The Engine Control Module (ECM) software program on about 159,700 of the above vehicles may cause illumination of the Malfunction Indicator Lamp (MIL) when no problem exists or under certain conditions allow heavy sooting of the turbocharger, exhaust gas recirculation valve and diesel particulate filter. Heavy sooting could damage emissions components and result in increased emissions. REPAIR; The Engine Control Module must be reprogrammed (flashed). This should not affect your fuel mileage anyway. Ask your Dealership if Emission Recall G30 applies to your vehicle. As stated in Recall J35, verify that Emission Recall G30 - Replace Oxygen Sensor Module and Reprogram ECM has been performed. If not, perform Recall G30 first. The Cab Compartment Node (CCN) module may have to be reprogrammed (Flashed) with new software. - It is recommended to discuss with the customer any required necessary maintenance as suggested in the owners manual.
