READINESS CODE 

Function 

The readiness code is an 8 digit number block that indicates the status of emission relevant diagnostics. 

If a diagnostic for a system has run through successfully, the respective digit of the number block is set from 1 
to 0. 

Diagnostics are performed at regular intervals during normal vehicle operation. After repairing an exhaust 
relevant system, the readiness code should be generated via a road test to ensure that these systems are working 
according to specifications. If a malfunction is recognized during diagnostic, it is stored in DTC memory. 

The readiness code is erased every time DTC memory is erased or when voltage supply is interrupted. DTC 
memory should therefore only be erased when there are DTCs stored. 

Read readiness code 

Requirements 

z

There must not be any DTCs stored in DTC memory. See DIAGNOSTIC MODE 3: CHECK DTC 
MEMORY
