- Correction of implausible CBS values is a 2-step process. First the value must be reset, then a correction factor must be applied. Step 1 is found under DIAGNOSIS - FUNCTION SELECTION - SERVICE FUNCTIONS - MAINTENANCE - CBS RESET - TEST PLAN. At the CBS reset screens, select the individual parameters with implausible CBS values and follow the on-screen instructions to reset them. Exit CBS.
- Step 2 is found under DIAGNOSIS - FUNCTION SELECTION - SERVICE FUNCTIONS - MAINTENANCE - CBS CORRECTION VEHICLE DATA - TEST PLAN. At the CBS correction screens, select individual CBS parameters to be corrected and follow on-screen instructions to correct them. For first correction factor(s) to be used, see CBS CORRECTION attachment No. 4 (SI B09 05 01). Note that if ENGINE OIL is to be reset, this must be reset first, followed by other parameters in the order they are displayed on the screen. If this order is not followed, corrupted values will result. Exit CBS correction.
