Incorrect Gear Ratio |
- With Fixed Gear Engaged Or During Gear Engagement Affected Clutches: A or B
|
- General description:
- The actual ratio has to stay in defined bounds. If one of the following malfunction criteria is detected, the fault code for the 3 corresponding clutches in that gear is set and a gear shift to a substitute gear is initiated. Depending on the behavior in the substitute gear, an additional fault code for only one or two clutches may be set to better distinguish the root cause of the problem. Shifting to further substitute gears is possible with the goal to identify a single defective clutch.
- Example:
- Malfunction criteria detection in 4th gear --> DTC for clutches "B or D or E" set and shifting to 5th gear (substitute gear). IF malfunction criteria in 5th gear still active --> DTC for clutches "B or D" set and shifting to 6th gear (substitute gear), ELSE --> DTC for clutch "E" set IF malfunction criteria in 6th gear still active --> DTC for clutch "D" set and shifting to 3rd gear (substitute gear), ELSE --> DTC for clutch "B" set IF malfunction criteria in 3rd gear still active --> DTC for "undefined clutches" is set because root cause cannot be related to a single clutch.

If one of the following malfunction criteria is detected, the fault code for the 3 corresponding clutches in that gear is set and a gear shift to a substitute gear is initiated. Depending on the behavior in the substitute gear, an additional fault code for only one or two clutches may be set to better distinguish the root cause of the problem. Shifting to further substitute gears is possible with the goal to identify a single defective clutch.
- Example:
- Malfunction criteria detection in 4th gear --> DTC for clutches "B or D or E" set and shifting to 5th gear (substitute gear). IF malfunction criteria in 5th gear still active --> DTC for clutches "B or D" set and shifting to 6th gear (substitute gear), ELSE --> DTC for clutch "E" set IF malfunction criteria in 6th gear still active --> DTC for clutch "D" set and shifting to 3rd gear (substitute gear), ELSE --> DTC for clutch "B" set IF malfunction criteria in 3rd gear still active --> DTC for "undefined clutches" is set because root cause cannot be related to a single clutch.
