CHECK ENGINE CONTROL MODULE SOFTWARE VERSION AND UPDATE IF NECESSARY (272 ENGINE)

This Service Campaign has been initiated because DCAG has determined that on the affected vehicles (see VIN range) the software for the engine control unit needs to be upgraded to correct a potential malfunction which could lead to an incorrect fuel/air mixture at low ambient temperatures. Under certain conditions, this can have a negative effect on starting the engine.

Please review the Effective Serial Number chart located on the following page.

Included is a sample copy of a letter which owners of the affected vehicles will receive.

Prior to performing this Service Campaign:
- Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
- Please review the entire Service Campaign bulletin.

Approximately 67,471 vehicles are affected.

Effective Serial Number Range

NOTE:
Every vehicle in the VIN range may not be included in the campaign. VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. VMI always overrides the bulletin in reference to a specific vehicle's inclusion in a particular campaign. Please also note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.

Procedure

A. CHECK VERSION OF ENGINE CONTROL MODULE SOFTWARE

Note - Prior to starting the procedure ensure to:
- Use DAS version 10/2006 with all Add On's or 11/2006 with all Add On's (including 2006-12-11-0665.)
- Follow the steps exactly as described in DAS
- Connect battery charger

1. Connect Star Diagnosis.
2. Check version of engine control module software.
- Follow the DAS path "Control units/ Drive/ ME 9.7- Motor electronics 9.7/ Control unit version."

3. Perform one of the following:
- Model280 in model series 171, 203: If software version is M272_KE_VC7/ VC8/ VC9, proceed to Subject B.
- Model350 in model series 171, 203, 209, 211: If software version is M272_KE_VC6/ VC7, proceed to Subject B.
- If software version is not one of the above versions: Disconnect Star Diagnosis; this campaign has been completed.

B. INSTALL ENGINE CONTROL MODULE SOFTWARE;
VEHICLES WITH M272_KE_VC6: ALSO INSTALL TRANSMISSION CONTROL MODULE SOFTWARE

1. Install engine control module software.
- Follow the DAS path "Control unit adaptations/ Control unit programming" and on-screen instructions.

NOTE: If the "No newer control module software was found" message appears when attempting to flash the control module, proceed to step 3 (vehicles with M272_KE_VC6 only) or step 4 (all other vehicles).

2. Perform SCN coding of engine control module.
- Follow the DAS path "Initial startup" and on-screen instructions.

3. Vehicles with M272_KE_VC6 only: Install and code transmission control module software.
- Install: Follow the DAS path "Control unit adaptations/ Control unit programming" and on-screen instructions.
- SCN coding: Follow the DAS path "Initial startup" and on-screen instructions.

NOTE: If the "No newer control module software was found" message appears when attempting to flash the control module, proceed to step 4.

4. Disconnect Star Diagnosis.

NOTE:
- In rare instances when flashing the ME9.7 the flash can fail due to network communications traffic on the Engine CAN, leaving the ME9.7 in 'Bootloader mode' If this flash failure occurs, simply pull the fuse(s) for the ESP Control Module and restart the ME9.7 Flash. Removing the fuse(s) stops the communication of the ESP Control Module and therefore reduces the communications traffic.
- The following allowable labor operation should be used when submitting a warranty claim for this repair:
