State: Adaption 1

[the adaption is reset to 0 after the battery has been disconnected.

In order to carry out adaption, the vehicle must be driven in overrun between 3 400 rpm and 1 600 rpm.

4 rpm ranges are displayed per load range. The ranges are bit coded and are given as a decimal number.

1 = field 1 is adapted

2 = field 2 is adapted

3 = fields 1 and 2 are adapted

4 = field 3 is adapted

5 = fields 1 and 3 are adapted

6 = fields 2 and 3 are adapted

7 = fields 1, 2 and 3 are being adapted

8 = field 4 is adapted

9 = fields 1 and 4 are adapted

10 = fields 2 and 4 are adapted

11 = fields 1, 2 and 4 are adapted

12 = fields 2 and 4 are adapted

13 = fields 1, 2 and 4 are adapted

14 = fields 2, 3 and 4 are adapted

15 = fields 1, 2, 3 and 4 are adapted

Example: 2/1 means the second rpm range (field 2) of load range 1

rl - load

n - rpm

The fields have different priorities

Priority I  field 1/1

Priority II  fields 2/2, 3/2 and 4/3

Priority III  fields 2/1, 2/3, 3/1, 3/3, 4/1 and 4/2

Fields following one another can be adapted within one rpm range if the fields with priority I and II have already been completely adapted, e.g. field 1/2 can be adapted after field 1/1. Field 1/3 is blocked.
