Generating Readiness Code

NOTE: While limited diagnostic information is available, vehicle manufacturer does not support diagnostic information using aftermarket scan tools. To properly diagnose vehicle, it is recommended to use VAS 5051 scan tool with VAS 5051/1 adapter cable or VAG 1551 scan tool with 1551/3A adapter cable and VAG 1598/31 test box.

NOTE: During readiness code generating procedure, if test result is indicated as "OK" after selecting a display group, testing has already been carried out and it is okay to proceed to next work step.

Readiness code must be generated when Engine Control Module (ECM) if ECM memory is cleared, battery voltage is disconnected or ECM is disconnected. To generate readiness code, vehicle must be stationary, transmission in Park or Neutral, all electrical consumers off, A/C switched off and coolant temperature at least 176° F (80° C). If possible it is best to warm-up vehicle by test driving. Connect VAS 5051 or equivalent scan tool to DLC. DLC is located behind cover under left side of steering column.

Using scan tool, retrieve DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES . If no DTCs were stored, go to next step. If DTCs were stored, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . Using scan tool, clear DTC memory. See FUNCTION 05 - CLEARING DIAGNOSTIC TROUBLE CODES . After clearing DTC memory. Follow scan tool instructions to complete readiness code generation. Using scan tool, observe display group 086 in display field 1. See Figure and Figure . Readiness code should display "0 0 0 0 0 0 0 0 0". If readiness code displays as specified, continue DTC testing or, testing is complete.
