controller:
x x x x x x x x
1 a fault is entered in the fault memory; interrogate fault memory
0 not assigned
0 not assigned
1 limited dynamics active
1 Lambda controller on stop
1 Lambda controller switched on
1 Lambda probe operational
1 Mixture condition:
display = 1: = mixture too rich
display 0: = mixture too lean
Note
t Each individual number of the 8-digit numerical block is designated as "bit".
The bit sequence (which is displayed by the 8-digit numerical block) is read from right to
t left. The first bit informs for example about the mixture condition, the eight bit displays if a
fault is stored in the fault memory or not.
If the fifth bit is set to "1" (limited dynamics active), however the lambda control is
t
controlled in a constant load range (i.e idling or drive with constant engine speed).
t Normally the first bit (mixture condition) must continuously jump between "0" and "1".
