CORRECTION

On the affected vehicles, reprogram/recode control modules with SSS loaded with CIP 17.1 or higher. After programming, using DIS/GT1, perform CBS data correction/reset as described in the procedure below.

  • After automatic determination, select: Function Selection, Service Functions, Maintenance, and then Test plans.
  • From the list of test plans, first select and execute: "CBS engine oil functionality error S1214_RESBODME", to delete adaptation values.
  • Then, select test plan "CBS Reset - SCBS 6003", following by [1] "Engine oil" to clear incorrect CBS data.
  • Finally, select test plan "CBS correction of vehicle date - SCBS 6004", following by [1] "Engine oil". Calculate the correction factor (in %) using the attached "B121105 CBS correction" table (with example included). Enter the correction factor into the test module.
