Version Coding of Modification Year or Model Year Code in STAR Diagnosis

SERVICE INFORMATION

The vehicle Modification Year or Model Year coding is an identifier in which a series of system or equipment modifications of all areas of the vehicle are packaged. Some of these modifications may be significant enough that improper version coding could affect the CAN system's ability to communicate properly. The most common control modules to use the Modification Year coding are the Electronic Ignition Switch (EIS) and Central Gateway (CGW). Depending on the model, other control modules may require this coding as well.

Identification of Modification Year Codes:

If present on the vehicle, use the manufacturing or option codes listed on the vehicle data label (typically located under the hood or left or right side B-pillar) to determine the Modification Year. The following two codes need to be located:
- Model Year Code (800-809) (Fig 1, green box "804")
- Production Control Code (050-055) (Fig 1, red box "054")
  
  Fig 1: Manufacturing Or Option Codes On Vehicle Data Label
Use the EPC Net application to determine the Model Year Code and the Production Control Code by following the menu bar path: Functions -> Datacard. The following two codes need to be located in the SA codes portion of the window:
- Model Year Code (800-809) (Fig 2, green box "805")
- Production Control Code (050-055) (Fig 2, red box "055")

NOTE: The exact position and numeric value of the Model Year Code and the Production Control Code may be different from this example (Fig 1, Fig 2), depending on the number of options fitted on the vehicle and year of production. The production control code (050-055) is a secondary identifier and may not be present on all vehicles.

STAR Diagnosis Version Coding Settings:

When version coding a specific control module in STAR Diagnosis, select the appropriate coding line that matches the codes found on the vehicle data label. Fig 3 depicts a typical STAR Diagnosis screen and version coding choices for a 211.065 CGW control module, in the red box.

NOTE: If the vehicle was produced prior to the first modification year listed in STAR Diagnosis version coding choices, then "Start of production" choice may be appropriate. Read any applicable notes on STAR Diagnosis screens for further direction. Fig 4 is an example of the note on a 211 STAR Diagnosis CGW screen.
