Update Engine Control Module Software

This Service Campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-Benz and Freightliner Sprinter vehicles, has

determined that humidity can enter the exhaust gas recirculation (EGR) valve which may cause an electrical short circuit. As a result, the feedback

signal from the valve to the engine control module (ECM) may fail. As a consequence, the EGR valve may be switched-off and the vehicles will

experience a loss of power and enter a limp home mode. In addition, certain software parameters in the ECM may not respond properly to brief

control deviations of the EGR valve position. Under certain circumstances, this ECM programming can cause an unfavorable response which can

deactivate the periodic cleaning function of the EGR valve. If the control deviation occurs twice within two consecutive driving cycles the MIL will

be illuminated. To correct these conditions, Dealers will update the Engine Control Module software at the next workshop visit.

Prior to performing this Service Campaign:

^ Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.

^ Please review the entire Service Campaign bulletin and follow the repair procedure exactly as described.

Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.

^ In the event of software/SCN update issues, contact Star Diagnosis User Help Desk.

^ Refer to Star Diagnosis System (SDS) Best Practices Guide

A. Check for Mobility Lift and PSM

1. Check for mobility lift: If yes proceed to step 2. If no proceed to Subject B.

2. Check for original equipment PSM (option code SA ED5): If yes proceed to Subject B. If no do not update engine control module software, refer

to: LI27.60-N-056078.

B. Update Engine Control Module Software

1. Connect Star Diagnosis to vehicle.

2. Install SCR control unit software: Control units / Drive / SCR control unit Adblue / Control unit adaptations / Control module programming

3. Perform programming of CDI control module: Control units / Drive / CDI 6 common rail injection / Control unit adaptations / Control module

programming.

4. Follow on-screen instructions.

5. Check fault memory: If fault memory16CE00 and/or 16CF00 is present, delete it by pressing the F9 button.

Note:

^ After updating SCR software, the software status should be: 07.37.00

^ After updating CDI software, the software status should be: 12.14.00
