Readiness code

Reading readiness code
Operation
The readiness codes are two eight-digit numerical codes
which indicate the status of the emission-relevant diag-
noses.
If the diagnosis for a system was successfully performed
(e.g. exhaust gas recirculation system), the relevant po-
sition of the numerical code is set from 1 to 0.
This diagnosis is performed at regular intervals during
normal driving. If repairs have been done on a system rel-
evant for the exhaust gas it is recommended to generate
the readiness code as this guarantees that the systems
operate according to the specifications. If a fault is detect-
ed during the diagnosis it is entered in the fault memory.
Readiness code is erased, i.e all relevant points will be
set to 1, through deletion of the fault memory.
Generation of readiness code refers to the activation of
the diagnostic functions such as diagnosis of fuel supply,
diagnosis of other systems etc.
